1 Introduction: Signs of erosion in the quality of democracy in EU member states

All European Union (EU) member states must comply with the Copenhagen Criteria (1993) and commit to upholding the conditions set out in Article 2 of the Treaty on European Union (TEU), namely “the values of respect for human dignity, freedom, democracy, equality, the rule of law, and respect for human rights […]” (European Union 2007). The EU is so far the only supranational organization that ties membership to the fulfilment of democratic and constitutional conditions (Kneuer 2007). In addition, the EU has numerous instruments at its disposal for sanctioning deviant behaviour (including Article 7 TEU, infringement procedures), and can thus be described as a promoter and guardian of democratic principles in its member states (Schimmelfennig 2009).

However, democracy in the EU has faced challenges for almost 15 years now. As early as 2007, the Nations in Transit Report identified anti-democratic tendencies in the young Central and Eastern European member states (Puddington 2011; Walker and Habdank-Kolaczkowska 2012). ErosionsFootnote 1 of democracy have progressed furthest in Hungary and Poland: In Hungary, the concentration of power of the national populist party Fidész under Prime Minister Victor Orbán has steadily increased since 2010. As a result, in 2018, Hungary became the first EU member state ever to be classified as partially free by Freedom House (Freedom House 2019; IDEA 2021). Poland has also seen continuous erosions since the Prawo i Sprawiedliwość (PiS) party came to power, such as a series of measures that undermine the independence of the judiciary, allow PiS to dominate the media, and silence criticism from civil society (Freedom House 2019). Neither Hungary nor Poland could join the EU, were they not members already, as they currently no longer meet the Copenhagen criteria (Sapper and Weichsel 2018). Developments that threatened media independence were also observed in other EU countries such as the Czech Republic and Slovakia in 2018 (Freedom House 2019). In addition, far right parties such as Vox in Spain, made electoral gains. In some cases they even entered government (e.g. Estonia in 2020, Austria in 2017, Freedom House 2020). Croatia, Lithuania, Bulgaria and Romania faced problems in the fields of corruption and organized crime as well as in the independence of the judiciary (Merkel 2010, p. 39). Nevertheless, the risk of a reverse wave in young or even old democracies was hardly addressed in the literature until the mid-2000s. Since then, scholars have published studies that tend to be rather pessimistic about the evolution of democracy—including predictions of a decline of democracyFootnote 2 or a reverse wave (Diamond 2008, 2015; Puddington 2008a). This assessment is not shared by everyone, though (Levitsky and Way 2015; Schmitter 2015).

Many studies analysing erosions in the quality of democracy are based on the assessment of individual cases (Ágh 2016; Andersen 2006; Krekó and Enyedi 2018) or a small set of cases (Frankenberger and Graf 2011; Ganev 2013; Kneuer 2011). Studies dealing with a middle or a large set of cases are relatively rare (Erdmann 2011; Svolik 2008). Studies dealing with EU member states focus mainly on Central and Eastern European countries (Bochsler and Juon 2020; Kapidžić 2020; Kelemen 2020; Ziemer 2020) since young democracies are considered to be particularly vulnerable to detrimental systemic developments (Erdmann 2011; Pickel 2012Footnote 3). But there is hardly any systematic comparative analysis dealing with the decline of democracy in all 28 EU member states (Smolka 2019). Moreover, many studies rely on democracy measures such as Freedom House, Polity IV or Bertelsmann Transformation Index, which cannot map gradual changes in the quality of democracy (Bühlmann et al. 2012, p. 520; Erdmann 2011, p. 39, 44; Pickel 2012, p. 2Footnote 4; Pickel et al. 2015, p. 497, 2016, p. 2).

This article seeks to fill this gap by examining whether signs of erosions of democracy in EU member states reflect losses in the quality of democracy or even a decline in democracy, and whether patterns can be deduced. In addition, the role of the EU in terms of its ability to prevent such developments in its member states is discussed. This is all the more important because the member states have committed themselves to fulfilling the Copenhagen criteria and stable and functioning democracies in the member states are crucial for the functioning of the EU. I rely on Bühlmann et al.’s (2008a) theoretical concept of quality of democracy and Erdmann’s (2011) definition of a decline of democracy. The Democracy Barometer data set—an index designed to measure the quality of democracy—is used to analyse the decline of democracy in the 28 EU member states between 2004 and 2016. In addition, the role of the EU as a guardian of democracy and the rule of law in its member states is discussed. I expect that the new EU member statesFootnote 5 are affected more often from a decline of democracy than the old ones. My expectation is based on the assumption that young democracies are more prone to cycles of democratic gains and regressions (Pickel 2012)Footnote 6. Findings (Pickel 2012)Footnote 7 indicate a positive influence of the democratic establishment on its stability, i.e. the length of time a country is a democracy. In addition, the majority of reports on violations of democratic principles refer to the new member states of the EU. Restrictions of civil liberties such as freedom of the press are frequently mentioned, but also attacks on the rule of law. Therefore, I assume that the principle of freedom is more often affected by erosions than the principles of equality and control.

The remainder of this article is organized as follows. Section two elaborates the theoretical concept of the quality of democracy and the decline of democracy, from which the criteria for the empirical analysis are derived. Section three presents the research design, including case selection, data description and operationalization of a decline of democracy. The criteria from section two are used in section four to empirically analyse whether the EU member states show losses in the quality of democracy or declines of democracy. Based on the existing literature, section five briefly discusses the EU’s role in combating decline of democracy in its member states. The final section concludes.

2 Democracy—quality and decline

2.1 The quality of democracy

“The analysis of the quality of democracy—that is an empirical scrutiny of what ‘good’ democracy is about—requires not only that we have a definition of democracy but also that we establish a clear notion of quality” (Morlino 2004, p. 5). The notion of democracy that underlies the concept of quality of democracy is thus crucial for the analysis of the quality of democracy and the decline of democracy (Osterberg-Kaufmann et al. 2020, p. 301). In recent years, numerous researchers have presented different conceptualizations of the quality of democracy at the macro level (Munck 2016; Pickel et al. 2015). It is generally agreed upon that “the concept [quality of democracy, T.S.] is applicable only to those cases that have been determined […] to meet the standard of the baseline concept of democracy” (Munck 2016, p. 9). In this regard, minimalist definitions of democracy (e.g. Dahl 1971) are considered inadequate because they do not allow researchers to capture the concept of democracy by degree (Erdmann 2011; Morlino and Carli 2014). By contrast, Merkel et al. (2003) provide a sophisticated mid-range definition of democracy. It goes beyond the electoral principle and includes other liberal functions of democracy such as the rule of law (Bochsler and Juon 2020).

Merkel et al. (2003, p. 47) define democracy as a set of institutional minima containing, first, a vertical dimension of democratic rule, namely vertical checks on the balance of power, the right of active and passive suffrage and effective fundamental participation rights. Second, it comprises a horizontal dimension, that is checks and balances. Third, it has a transversal dimension, namely the assignment of the effective power to govern to democratically legitimized rulers. The three dimensions of the definition correspond to the three fundamental principles of democracy, which are equality, freedom and control. The definition by Merkel et al. (2003) does not consider any outcomes of democracy, focusing solely focus on structures and procedures of a democratic system. They mainly capture participation and representation in terms of “government of the people and by the people” (Lincoln Gettysburg Address 1863) (Siaroff 2009). The definition of democracy by Merkel et al. (2003) is further elaborated as the one by Dahl (1971), but it is still based on the basic theoretical principles of democracy. Furthermore, the definition includes Merkel et al.’s (2003) model of a liberal democracy (embedded democracy) and, accordingly, the theoretical basis of the Democracy Barometer (DB).

The concept of the quality of democracy on which the DB is based (Bühlmann et al. 2008b) and the one developed by Diamond and Morlino (2005) and Morlino (2009) are among those that have strongly influenced the debate. Unlike Bühlmann et al. (2008a), Diamond and Morlino (2005) present a substantial definition of the quality of democracy (Pickel et al. 2016).Footnote 8 It is not taken into consideration, since the definition of democracy used in this article is a procedural one and does not contain any outcomes. Consequently, the theoretical approach presented by Bühlmann et al. (2008b), which is seen as one of the most profound theoretical approaches (Munck 2016), is used. Their concept of the quality of democracy is based on Merkel et al.’s (2003) definition of a liberal democracy and the concept of the embedded democracy. Thus, the three fundamental principles of democracy—political equality, freedom and control of power—are at the core of their concept. From the three principles, they theoretically derive nine democratic functions (transparency, participation, representation, individual liberties, rule of law, public sphere, competition, mutual constraints and government capability) which are further disaggregated into 18 components, 51 subcomponentsFootnote 9 and 98 indicators (Bühlmann et al. 2012; Engler et al. 2020).Footnote 10 The quality of democracy depends on the degree to which the principles, functions and its components are fulfilled (Bühlmann et al. 2007). The authors assume that the quality of a democracy is high if the nine functions are fulfilled to a high degree. Nevertheless, he points out that the simultaneous maximization of all nine functions is not possible due to the existing tensions between freedom and equality. Since democracies are systems whose development is constantly negotiated by political and social forces, democracies can weight and optimize the nine functions differently and thus influence the quality of their democracy.

2.2 The decline of democracy

As one of the few researchers, Erdmann (2011) has theoretically conceptualised the decline of democracy. He terms the reverse process of democratization—i.e. the transformation from democracy, starting with the loss of quality—as decline of democracy. Erdmann defines the decline of democracy as “[…] a deterioration of quality in one of the two central dimensions of democracy—freedom and equality—and in one additional one, i.e. the (horizontal) control of power; it describes a negative variation within the democratic regime type” (Erdmann 2011, p. 24). A democratic political system can show a decline in quality and then turn into a defective democracy, a hybrid or an authoritarian regime. The process can be either slow and gradual, moving from quality loss to a hybrid regime, or fast and short, ending in an authoritarian or totalitarian regime without passing through the hybrid stage. In line with research on the consolidation of democracy, three types of decline of democracy can be derived: a silent regression, i.e. a gradual decrease in freedoms, rights and processes which are important for democracy (O’Donnell 1995, p. 25), a backslide, i.e. a relapse from democracy into a hybrid regime, and a breakdown, i.e. the collapse of democracy. From an empirical perspective the most common patterns are silent regressions and backslides, whereas breakdowns are relatively rare (e.g. Venezuela, Thailand and Honduras; Erdmann 2011, p. 28; Erdmann and Kneuer 2011, p. 13; Levitsky and Way 2015, pp. 52–53).

To date, several approaches have addressed the decline of democracy mainly in terms of regime change “but not as a decline in the quality of democracy” (Erdmann 2011, p. 39). In liberal democracies, the decline of democracy can result in a significantly lower level of quality which can lead to the classification of a liberal democracy as a diminished subtype of democracy, such as a defective democracy (Merkel 2004), an electoral democracy (Diamond 1999; Erdmann 2011) or illiberal, inegalitarian or unaccountable democracies (Lauth et al. 2021). Declines in the quality of liberal democracy are more nuanced than in the case of regime changes. As early as 1996, Huntington pointed out the danger of a gradual regression of democracy in the young democracies of the third wave of democratization: “the problem is not overthrow but erosion: the intermittent or gradual weakening of democracy by those elected to lead it” (Huntington 1996, p. 8). Merkel and Puhle Merkel and Puhle (1999) also saw the danger of a creeping erosion, hollowing out and de-liberalization of young democracies by freely elected governments. Consequently, the literature often refers to the age of a democracy as an important factor in a democracy’s susceptibility to deteriorations in the quality of democracy (Erdmann 2011; Erdmann and Kneuer 2011; Pickel 2012Footnote 11; Svolik 2008). It is assumed that young democracies—especially those of the third wave of democratization after 1989—are more prone to a decline in the quality of democracy because they have a lower degree of institutionalization and consolidation than political systems that have been democracies for a longer period of time. Moreover, young democracies are supposed to get more often caught in cycles of democratic gains and setbacks (Pickel 2012Footnote 12). But even established industrialized democracies such as the United States under president Trump (Freedom House 2020) have experienced declines in their quality of democracy since the end of the Cold War (Erdmann 2011). Thus, the decline of democracy mainly affects young democracies founded during the third wave of democratization but old democracies are also not immune to it (Diamond 2015, p. 142; Erdmann 2011, p. 28; Erdmann and Kneuer 2011, p. 12; Pickel 2012, p. 2Footnote 13). A reduction in quality is possible at any time and at any stage of the development of a democracy.

Assumption 1:

Within the European Union, a decline of democracy occurs more frequently in the new EU member states than in the old member states.

Within the recent past, violations of basic democratic principles have been recorded in several new EU member states. Civil liberties and political freedoms have been particularly affected, such as the inadequate protection of the freedom of the press, political pluralism or the rule of law in Hungary, Poland and Slovenia. For example, in Hungary the new media law (2010) and the fourth amendment to the constitution (2013) came into force. In 2018 Victor Orbán enacted the Anti-NGO Bill (Otto 2021). Poland’s ruling party, the PiS, for instance restricted women’s and LGBTQI+-rights in the recent past and in 2020 the Polish Constitutional Court declared abortion laws unconstitutional. In Slovenia, Janez Janša restricted the freedom of expression by attacking critical public media outlets in 2020 (Kube et al. 2020, p. 13). Occasional violations of civil liberties have also been observed in old EU member states. In Italy, for instance, press freedom was severely restricted under Berlusconi in 2009.

Assumption 2:

Of the three basic democratic principles, freedom rights are more frequently affected by deteriorations than the principles of equality and control.

Whether the negative trends in the quality of democracy predicted since the first half of the 2000s (Diamond 2008, 2015; Puddington 2008) and observed in several regions of the world (Lührmann et al. 2019) also apply in principle to the EU member states needs to be verified. In addition, the assumption that young democracies have a higher susceptibility to deteriorations in the quality of democracy and a decline of democracy compared to old democracies needs to be analysed (Erdmann 2011; Pickel 2012Footnote 14; Puddington 2011; Walker and Habdank-Kolaczkowska 2012). The fear that we could be at the beginning of a reverse wave of democratization, especially in the Central and Eastern European countries, can also be assessed in this way (Diamond 2015).

3 Research design

3.1 Case selection and data

In the analysis, I study all member states that successfully completed the EU accession process according to article 49 TEU.Footnote 15 Hence, 28 member states are analysed. All countries joining the EU must have “[…] achieved stability of institutions guaranteeing democracy, the rule of law, human rights and respect for and protection of minorities […]” (European Council 1993, p. 12)—i.e. at the stage of accession, the member states must be consolidated democracies.Footnote 16 This condition is also relevant for the assessment of a decline of democracy because “[u]nless democratic elements have been established they cannot vanish” (Pickel 2012, p. 4)Footnote 17. The starting point of the analysis is the year 2004, the year of accession of the eight Central and Eastern European countries as well as Cyprus and Malta.Footnote 18 As second, third and fourth points in time, the years 2008, 2012 and 2016 are chosen based on data availabilityFootnote 19. Moreover, the period of analysis includes the time span for which erosions in the quality of democracy are described (Puddington 2011).

3.2 Operationalization: Loss of quality of democracy and decline of democracy

According to Erdmann’s (2011) definition a decline of democracy is present when the overall quality of democracy deteriorates as well as in one of the two central dimensions of democracy—freedom and equality—and in the dimension of control. If this condition is not met, that is, if there is no deterioration in the overall quality, the control dimension and in at least one of the two dimensions of freedom and equality, the development does not represent a decline of democracy but a loss of quality. The most commonly used indices to measure the level of democracy are Polity IV, Freedom House or V-Dem. Freedom House and Polity IV consistently rank the old and new EU member states in the upper end of their scale—with a few recent exceptions. Since the article only looks at democracies (EU member states) and changes in the quality of democracy are more nuanced here than in cases of regime changes, an index is required which allows to reveal different degrees of quality as well as minor violations of the principles of freedom, equality and control of power (Pickel 2012, p. 2)Footnote 20. Moreover, the article draws on Merkel et al. ’s (2003) definition of liberal democracy, more specifically the embedded democracy. The Democracy Barometer data (DB) meets all of these requirements: First, it is based on Merkel et al.’s theoretical framework—the basis of Bühlmann et al.’s (2008a) theoretical concept of the quality of democracy. Second, it is a macro-level index measuring and comparing subtle differences in the quality of established democracies (Engler et al. 2020). In addition, it “provides a highly differentiated set of components […] and a number of variables and indicators for measuring democracy” (Erdmann 2011, p. 40).

The DB consists of 98 indicators which present the lowest level of the concept. These indicators are aggregated into 51 subcomponents, 18 components, 3 fundamental principles of democracy and finally the overall quality score. Unlike other indices, the DB takes into account both the “rules in law” and “rules in use” (Engler et al. 2020, p. 54). It is primarily based on objective aggregate data and not on subjective expert assessments (Bühlmann et al. 2012).Footnote 21 Due to missing theoretical thresholds for a variety of indicators used by the DB, the authors decide to standardise the indices by identifying the “best and worst practice in established democracies” (Merkel et al. 2014, p. 5). Since the 15 old EU member states are to be the benchmark for the analysis of the quality of democracy and the decline of democracy in the 28 EU member states, the DB standardized by (Engler et al. 2020) cannot be used. Instead, an EU blueprint sample, consisting of 14 old EU member states from 1993 until 2003, is compiled on the basis of the raw data.Footnote 22 The year 1993 is chosen as a starting point because it was the year the Copenhagen criteria were defined. The Copenhagen criteria reflect the democracy level of the old member states and were the benchmark to be achieved by acceding states. The period ends in 2003, as in 2004 Cyprus, Malta and eight of ten Central and Eastern European countries joined the EU. Based on the authors’ approach (Merkel et al. 2014), all indicators in the blueprint sample are rescaled according to the best and worst practice, i.e. the lowest empirical value of each indicator in the blueprint sample is assigned 0 and the highest empirical value is assigned 100. Then, all EU member states from 2004 until 2016 are included in the dataset. Their values are rescaled in relation to the best and worst practice case of the EU blueprint sample. Thus, it can be analysed in detail how the EU member states perform and if only new EU member states or also old EU member states deviate from the EU-14 benchmark. By calculating the difference values between 2004 and 2008, 2008 and 2012 as well as 2012 and 2016, a loss of the overall quality of democracy or a decline of democracy in the EU members can be determined.

4 Analysis

Using the DB data a descriptive analysis is conducted to determine whether there has been a decline in democracy in the EU member states. In addition, I analyse which fundamental principles are most affected by deteriorations and if patterns exist.

4.1 Loss of quality of democracy

The descriptive analysis shows a somewhat worrying picture. The difference scores of the quality of democracy from 2004 to 2008 and 2008 to 2012 reveal that the number of EU member states which display a loss in their quality of democracy increases from 9 to 21 between the first two periods (Fig. 1). The number of countries with an improvement in their quality decreases by almost two thirds, from 18 to 6 states. Surprisingly, the old EU member states make up the majority of countries with negative difference values: In 2008, eight old (Denmark, Finland, Greece, Ireland, Italy, Netherlands, Spain, United Kingdom) and only one new member state (Estonia) belong to this group. In 2012, the number increases to 13 old (all old ones except Italy and United Kingdom) and eight new member states (Bulgaria, Cyprus, Estonia, Hungary, Malta, Romania, Slovakia, Slovenia). In contrast, the new member states outweigh the old ones in terms of positive difference values: In 2008, eleven new members and seven old ones can be assigned to the group. In 2012, there are four new members and only two old members in this group. Hungary and Spain are the countries most affected by a loss in the quality of democracy between 2008 and 2012. In Spain, this can be attributed largely to the deterioration of the function governmental capability. In Hungary, the functions competition, participation and individual freedoms have been restricted to a considerable degree (Smolka 2019, p. 365, 379, 385, 391).Footnote 23

The number of countries showing a loss in the quality of their democracy is decreasing again between the second (2008–2012) and the third period (2012–2016) from 21 to 17 (Fig. 1). Again, there are more old member states with a negative difference score of the quality of democracy than new member states. However, the old and new member states almost equalize—nine old states (Austria, Belgium, France, Ireland, Luxembourg, the Netherlands, Portugal, Spain, United Kingdom) and eight new states (Croatia, Estonia, Hungary, Lithuania, Malta, Poland, Romania, Slovakia) show a loss in the quality of democracy. But in the third period, and for the first time, more old (six) than new (five) EU members show positive developments in their quality of democracy. Thus, a significantly more positive trend can be observed, although the number of member states with a loss in their quality of democracy is higher than in the first period (2004–2008: 10 vs. 2012–2016: 17). The comparison of the difference values also shows that only the Czech Republic and Latvia are able to improve their quality between the three time periods. Consistently negative difference values can be found in Ireland, the Netherlands and Spain. Based on the heterogenous descriptive results, no pattern can be discerned with regard to the loss in the quality of democracy. This also applies to the countries that were severely affected by the Global Financial Crisis and European Sovereign Debt Crisis which falls into the second period of analysis: Greece, Ireland, Italy, Portugal, Spain, Cyprus, Hungary, Latvia, Romania, and Slovenia. In the second period, the loss in the quality of democracy varies greatly among these countries (e.g. Spain, Slovenia). Italy and Latvia can even improve their quality. In contrast, in EU members such as Germany or Slovakia, which were not as badly affected by the crisis, the quality of democracy deteriorated. The two countries most affected by a loss in the quality of democracy between 2012 and 2016 were Ireland and the United Kingdom. In Ireland, this can be attributed largely to the deterioration of the functions public sphere and rule of law. In the United Kingdom, the functions individual liberties and governmental capability have deteriorated significantly. However, it is important to note that the starting level of the quality of democracy of the old member states was significantly higher than that of the new member states. Thus, the EU should not only keep an eye on the quality of democracy in its new member states, but also on that of its old members.

A closer look at the year-to-year changes in the quality of democracy shows that in almost half of the years (five out of 12) the negative developments outweigh the positive ones (Fig. 2). Most of the negative changes occurred between the years 2010 (16) and 2016 (14). In the years 2012 to 2014, more than two thirds of the EU members showed a loss in quality.

4.2 Decline of democracy

To determine whether the losses in the quality of democracy also represent a decline of democracy, the three basic democratic principles and the overall quality have to be analysed (Erdmann 2011, p. 24).

In the first period (2004–2008), only five out of nine member states, showing a loss in their quality, can be assigned to the group with a decline of democracy (Table 1). These countries reveal a loss of their overall democratic quality as well as deteriorations in the principles of freedom and/or equality, and in the principle of control. Within this group, Denmark, Finland, and Italy reduce their overall quality and all three basic principles. Estonia decreases the areas of equality and control, Ireland the areas of freedom and control. Accordingly, the principle of freedom and equality are equally affected by deterioration in countries where a decline of democracy is present. Although five countries do not belong to the group with a decline of democracy, they must be considered as being at risk: Greece, the Netherlands, Spain and the United Kingdom, on the one hand, reduce their overall quality as well as either the principle of equality, freedom or control. Cyprus on the other hand, worsens the principle of control and freedom but not the overall quality. In total, 16 of the 27 countries worsen the area of freedom, twelve the area of equality and eight in the area of control. On a positive note, however, France, Poland and Romania can improve both their overall quality and the three fundamental principles.

Table 1 Difference values of the overall quality of democracy, and the three democratic principles freedom, equality, and control (2004 to 2008)

A closer look at the old and new member states shows that in 2008 there are four old member states and only one new member state with a decline of democracy. Moreover, only old EU members (Denmark, Finland, Italy) deteriorate all three principles. Therefore, in the first period the first assumption is disconfirmed. Instead, the opposite is the case: Democratic dismantling in form of a decline of democracy is much more common in the old EU member states than in the new ones. However, the second hypothesis is confirmed: In nearly two thirds of the member states freedoms are threatened. It is by far the democratic principle most affected.

From 2008 to 2012, the number of countries showing a loss in their overall quality more than doubles from nine to 21 member states. 13 countries can be assigned to the group of countries with a decline of democracy (Table 2). This is an increase of 86% between the two periods. Within the group of countries showing a decline, Austria, Greece, Hungary, Slovakia, and Spain reduce not only their overall quality but also the level of all three principles. Bulgaria, Cyprus, Estonia, France, Germany, Ireland, and Portugal only worsen the principle of control and freedom while improving the equality. The only country with a decline of democracy that worsens equality but improves freedom is Romania. The remaining eight countries with losses in their overall quality show deteriorations in the principle of freedom (Belgium, Finland, the Netherlands, Sweden), freedom and equality (Denmark, Malta) or control (Slovenia). The countries have thus narrowly missed the deterioration in form of a decline of democracy. Again, the principle of freedom (20) is more often affected by deteriorations than the principle of control (16) and equality (9). In 2012, only two member states—Poland and the United Kingdom—are able to improve their overall quality and all three principles.

Table 2 Difference values of the overall quality of democracy, and the three democratic principles freedom, equality, and control (2008 to 2012)

A comparison of the old and new member states shows that in 2012 seven old EU member states—although not exactly the same as in 2008—belong to the group of states experiencing a decline of democracy. The number of new member states, however, increases from one in 2008 to six in 2012. Estonia and Ireland show a decline of democracy in both periods. The decline occurs in old member states slightly more often than in the new member states. Besides, deteriorations in all three principles occur in five countries, namely in the three old EU members Austria, Greece, and Spain as well as in the two new members Hungary and Slovakia. Thus, the first assumption must be rejected, although the number of old and new member states with a decline of democracy converges. Again, the second assumption holds true—the principle most affected by deteriorations is freedom, followed by control.

In 2016, only eight out of 17 member states showing a loss of their overall quality can be assigned to the group with a decline of democracy (Table 3). Thus, the number of EU member states with a decline of democracy decreases again between the second and third period. The results show that only the three countries Hungary, Ireland and Lithuania simultaneously reduce their levels of freedom, equality, and control. Belgium, Poland, Slovakia, and the United Kingdom worsen their level of freedom while improving their level of equality. Estonia shows the contrasting development—improvement of freedom and deterioration of equality. In 2016, nine countries must be classified as jeopardized: Croatia, Luxemburg, and Portugal decrease their overall quality as well as freedom and equality, Malta and Romania worsen their overall quality and control. Austria, France, the Netherlands, and Spain reduce their overall quality and freedom. Once again, the principle of freedom is most frequently affected by deteriorations (17), followed by the principle of control (15) and equality (9). This time, there are again three countries (Bulgaria, Finland, Sweden) that can improve their level in all three dimensions.

Table 3 Difference values of the overall quality of democracy, and the three democratic principles freedom, equality and control (2012 to 2016)

In 2016, for the first time in the period under review, more new than old EU member states show a decline of democracy. Now five new and four old EU members display this development. Thus, the first assumption has to be confirmed. Again, the second assumption is supported by the empirical findings. The principle of freedom (17) deteriorates more often than control (15) and equality (9).

If all three analysis periods are considered, it becomes apparent that only two EU member states consistently show a decline of democracy: Estonia and Ireland. Two countries show a decline of democracy at two points in time each—Hungary and Slovakia in 2008 and 2016. Here, the new member states outnumber the old members. But over the entire period of analysis, more old members than new members have experienced a decline of democracy at least once: Twelve old member states (all except Luxembourg, the Netherlands, and Sweden) and eight new member states (all except Croatia, Czech Republic, Latvia, Malta, Slovenia). Although the decline of democracy occurs in the new EU members more frequently in series and must thus be considered somewhat more permanent, the numerous declines in democracy in the old member states should not be neglected either.

A detailed analysis of the individual years 2005–2016 (Fig. 3) shows that serious deteriorations in the form of a decline of democracy occurred less frequently: At no time the number of member states with a decline of democracy exceed the number of member states without a decline of democracy. But in 2012 and 2014 the number of member states with a decline of democracy is the same as the number without a decline of democracy. Nevertheless, each year at least four countries had to be assigned to the group of countries showing a decline of democracy. Therefore, the control dimension respectively the rule of law has been under severe pressure in the EU member states for some time now.

5 The role of the EU

The descriptive analysis has shown that neither the loss of quality nor the decline of democracy can be considered a rare phenomenon in the EU member states. On the contrary, the EU has been confronted with these negative changes in old and new member states for quite some time now. These developments exists even though the EU ties its membership to the fulfilment of democratic and constitutional conditions, namely the Copenhagen criteria (Kneuer 2007). A high quality of democracy and the prevention of a decline of democracy in its member states should be of great importance for the EU, since the EU can only be as democratic as its members are. Thus, the question arises as to why the EU is unable to counter these developments.

So far, the EU is only able to positively influence the democratic development of candidate countries—as the democratization and consolidation of the young democracies of the third wave of democratization shows (Kneuer 2007). However, the positive influence of the EU’s accession conditionality seems to fizzle out after accession (Ganev 2013). Empirical studies support this assumption by showing, that the EU is unable to prevent deteriorations in key dimensions of liberal democracy such as the rule of law or freedom of the press after accession (Bochsler and Juon 2020; Ganev 2013; Kelemen 2017; Smolka 2019). Looking explicitly at 19 democracies in Central and Eastern Europe, Bochsler and Juon (2020, p. 179) point out that “EU membership itself is not systematically associated with improvements of the quality of democracy”. At the same time, however, EU membership itself cannot be equated with deteriorations in the quality of democracy. The authors find no post-accession development patterns in Central and Eastern Europe. In this regard EU member states’ paths “are very heterogenous” (Bochsler and Juon 2020, p. 180). This conclusion, i.e. the heterogeneous positive and negative developments in the quality of democracy, applies not only to the new member states, but also to the old member states. Surprisingly, they represent the majority of countries affected by a decline of democracy (see also Smolka 2019). Moreover, empirical analyses (regression analysis, Qualitative Comparative Analysis) show that neither differentiated integration, i.e. different forms of integration and enhanced cooperation between member states such as the European Monetary Union (Leuffen et al. 2013), nor Europeanization, i.e. repercussions of the European integration on the member states (Axt et al. 2007), can be considered as factors which prevent a decline of democracy in EU member states (Smolka 2019

The EU not only lacks a comprehensive instrument for monitoring basic democratic values in its member states and preventing deteriorations in the quality of democracy, but also, to some extent, the political will. In the European Parliament (EP), for example, belonging to a strong party family such as the European People’s Party (EPP) can avoid sanctions against difficult group members showing illiberal tendencies such as the Fidész Party (Müller 2013). In both the last and current legislative periods, Fidész is helping the EPP to maintain its lead (182 seats, 12 from Fidész) over the second largest party in the EP, the social democratic S&D group (154 seats). Despite provocations involving Jean-Claude Juncker, George Soros and conspiracy theory in the EP election campaign 2019 and calls for the expulsion of the Fidész party from the EPP, Manfred Weber and other EPP leaders rejected it. Instead, the EPP as a party suspended Fidesz, but not the parliamentary group, whose rules of procedure did not provide for such an instrument. Thus, the 12 seats of Fidész still counted to the EPP group and helped to confirm Ursula von der Leyen as President of the Commission. In January 2020 a committee of EPP “wise men” recommended to extent the suspension indefinitely, which EPP chairman Donald Tusk followed (Kelemen 2020; Ziemer 2020). On March 3, 2021, the EPP changed its rules of procedure so that Fidész MEPs can now be suspended. To avoid an official suspension by the EPP, Orbán announced the resignation of the Fidész MEPs on the same day. While in the case of Poland (PiS belongs to the European Conservatives and Reformists Party) the new EU Rule of Law Framework was very quickly applied in January 2016 and the European Commission asked the Council to activate Article 7 (1) TEU in December 2017, Hungary was able to bypass this dialogue procedure, despite strong criticism from EU institutions and member states. It only came under pressure in 2018 when the EP followed the initiative of Green MEP Sargentini and, with a two-thirds majority, called on the Council to use the preventive mechanism of Article 7 (1) TEU against Hungary. This time, even EPP members supported the initiative (Smolka 2019).

In addition, instruments such as Article 7 TEU are politically hard to activate, as they require a unanimous decision in the European Council. To circumvent the activation of Article 7 procedures and the resulting sanctions, like-minded countries may establish informal relations with each other. By using their veto power, autocratically inclined countries can thus protect each other. The mutual support of Fidész and PiS is a case in point. Alternatively, the Council can at least set in motion the preventive mechanism of Article 7(1) TEU, since its activation requires only a four-fifths majority. In the case of Hungary and Poland hearings and a detailed report by the Commission on the situation in Hungary and Poland led to the decision on September 22, 2020, that the conditions for ending the Article 7 proceedings were not met and that the proceedings would continue. Nevertheless, it is unlikely that the Council can even reach a four-fifths majority as Central and Eastern European countries are critical of the process. However, the political will to act is not always given in the European Council, and also in the European Commission (Kelemen 2020, pp. 489–490; Smolka 2019, p. 511). Even though the Commission is supposed to assess developments of democracy and rule of law in an unbiased manner and, if necessary, to trigger the Rule of Law Framework or the preventive mechanism of Article 7 TEU, “partisan considerations also play a role in the decision making of that body and in the preferences of particular Commissioners” (Lang 2017, p. 27).

Well aware that its current instruments are rather toothless and inadequate to combat a decline of democracy in its member states, the European Commission proposed a new financial condition in May 2018 that would allow the suspension of EU funds in cases of systemic rule of law violations (Blauberger and van Hüllen 2021, p. 1). After the European Council, the European Parliament adopted on December 16, 2020, the compromise of the “Regulation on a general regime of conditionality for the protection of the Union budget.” A first compromise was blocked by Hungary and Poland (Scheppele et al. 2020). Such an instrument is urgently needed, as the “EU funds have helped prop up authoritarian member government in Hungary” (Kelemen 2020, p. 490) and Poland. In the last budget period (2014–2020), Poland and Hungary were the largest recipients of the European Structural and Investment Funds. In Hungary, the EU co-financed 95 per cent of all public investments in recent years (Kelemen 2020, p. 490; Keszthelyi 2017). But research showed that “a significant portion of the EU funding allocated to Hungary has been channelled by the Orbán government into the pockets of Fidész cronies” (Kelemen 2020, p. 490); (Vachudova 2020, pp. 329–331). Hungary was therefore described as a “post-communist mafia state” by former Education Minister Bálint Magyar (2019). Nevertheless, Hungary and Poland were allowed to opt-out of participating in the European Public Persecutor’s Office. Thus, the EU is unable to investigate crimes against the EU budget such as fraud or corruption in both countries (European Commission 2020). The entry into force of the rule of law mechanism on January 1, 2021, was therefore all the more important. Yet, its purpose is not to combat violations of the rule of law in general, but to protect the EU’s financial interests against any kind of fraud, corruption and conflict of interest (Zwaan 2020). However, not only the future effectiveness of the mechanism is questioned, but also its’ application from January 1, 2021. The conclusions of the European Council (2020) provide for a delay in the application of the regulation, stating that the regulation shall not be brought into force before the European Court of Justice (ECJ) has given a ruling on its legality and “not before a complex consultation process with the member states produces ‘guidelines’ that will make clear how the mechanism will be used” (Scheppele et al. 2020). Although the conclusions are not legally binding (Alemanno and Chamon 2020), the Commission and EP are unlikely to override them. As announced, Poland and Hungary filed an action with the ECJ on March 11, 2021. Poland and Hungary see the regulation as a new procedure not provided for in the EU treaties and beyond control. In this way, they are preventing the mechanism from being applied for the foreseeable future. With regard to the effectiveness of the regulation, an in-depth analysis of the draft, which also holds true for the adopted version, concludes that the regulation “would indeed improve the speed and likelihood of sanctions compared to existing mechanisms, but lacks in the determinacy of conditions and procedures, thus undermining its perceived legitimacy and chances of success” (Blauberger and van Hüllen 2021, p. 1). Since the text of the regulation leaves a lot of room for interpretation, it can evolve into a pure anti-corruption measure or into a genuine rule of law mechanism (Jakab and Kirchmair 2020) and thus a much needed shield against the decline of democracy in the EU member states. But this, too—like the design and application of the already existing instrumentsFootnote 24—depends on the political will of the European Commission, the European Council and the European Parliament to act (Smolka 2019).

6 Conclusion: The EU still lacks the political will to act

Against the background of current developments in some EU member states such as Hungary, Poland, Slovenia or the Czech Republic, the debate on the quality of democracy and the decline of democracy continues to be highly relevant. Nevertheless, a systematic comparative analysis of a decline of democracy in the 28 EU member states, based on a sound theoretical concept and an index allowing a fine-grained analysis of the quality of democracy, is still missing. This article addresses these shortcomings by shedding light on the discussion about losses of quality and declines of democracy in two ways: First, a comprehensive theoretical basis is presented that allows to distinguish between the two concepts and to derive criteria for empirical analyses. For this purpose, I draw on the concept of liberal democracy by Merkel (2004), the concept of the quality of democracy by Bühlmann et al. (2008a) based on it, and Erdmann’s (2011) definition of the decline of democracy. Second, using the criteria, an empirical analysis of the state of democracy—namely the presence of losses of the quality of democracy and declines of democracy—in all EU member states between 2004 and 2016 is conducted. The analysis relies on the data of the Democracy Barometer, which was standardized with regard to the EU member states. In addition, the role of the EU and its possibilities for intervention in relation to these developments, e.g. Article 7 TEU, the “Rule of Law Framework” and the “Regulation on a general regime of conditionality for the protection of the Union budget” are discussed.

The results of the analysis paint a mixed, but rather gloomy picture: Apart from the first period of analysis (2004–2008), the majority of EU member states showed a loss in the quality of their democracy. Between 2004 and 2008 “only” nine countries recorded a loss in the quality of democracy, with five of the nine countries showing a decline of democracy. In the second period of analysis (2008–2012), the number of member states with a loss in the quality and a decline of democracy more than doubled: 21 states—and thus two-thirds of all EU member states—displayed a loss, and 13 countries even met the strict criteria for a decline of democracy. The picture improves somewhat in the last analysis period (2012–2016): The number of countries with a loss in the quality of democracy drops to 17, and the number of member states with a decline of democracy decreases to eight. In the first two analysis periods, more old than new member states show a loss in the quality and a decline of democracy. In the third analysis period the picture turns: Now, slightly more new than old member states register a decline of democracy. It is worrying, however, that Estonia and Ireland show a continuous decline in democracy. It is also alarming that the two most powerful EU states and EU founding members, France, and Germany, have shown a decline of democracy in the second analysis period. This, somehow, limits their ability to push for sanctions in the European Council—given that they do not even themselves comply with the standards they demand of others. Moreover, the results show that the democratic principle of freedom is more frequently affected by deterioration than the principles of equality and control. Overall, neither a pattern nor a general de-democratization trend or even a third reverse wave can be discerned from the results. Yet, the results should give cause for concern.

To counteract these negative developments, possible causes need to be looked at. A large number of explanatory mechanisms can now be found in the literature. These include for instance the rise of (ethno)populist parties and party leaders (Bochsler and Juon 2020; Vachudova 2020; Ziemer 2020, p. 258), the emigration of dissatisfied citizens as well as a weakened civil society and opposition (Kelemen 2020). In contrast, modernization theory, political culture, and differentiated integration and Europeanization can not fully explain the occurrence of the decline in democracy (Smolka 2019).

Illiberal democracy seems to be the new variety of authoritarianism that Huntington pointed out more than two decades ago. What makes this variant dangerous is the fact that it arises within the cloak of democracy (Krastev 2018). For the EU, the quality of democracy in its member states should be extremely important, because “[w]ithout stable and functioning democracies in member states, the EU would certainly have to redefine its self-image of being a community of values, of which democracy and rule of law are key principles […]” (Lang 2017, p. 13). Moreover, a high quality of democracy and the absence of declines of democracy in the member states should be of central interest to the EU, since the EU can only be as democratic as its member states. Thus, it is necessary to qualify the EU’s role as guardian of the democratic fundamental values. Time will show if—at least—the newly adopted “Regulation on a general regime of conditionality for the protection of the Union budget” will be effective in protecting the rule of law and stop the funding of authoritarian governments in their own ranks (Blauberger and van Hüllen 2021; Kelemen 2020; Scheppele et al. 2020). There is a need for further research and recommendations for action on how to make the façade crumble and reveal the “ugly” face of mild autocratic regimes, for instance how “mafia-state structures” can be broken up, the independence and diversity of media can be reinstalled and a strong civil society and opposition can be re-activated. Now, the EU is at a crossroad: appeasement with autocrats or defence of fundamental democratic values. For the EU to emerge victorious from the current severe challenge, not only powerful tools need to be developed. It is much more important that the political will to act is established in all EU institutions. There is an urgent need for action.
