Abstract

In 2002, Germany reformed its law of obligations (Schuldrechtsreform) and amended the German Civil Code (BGB) dated 1 January 1900. The 2002 amendments, which are considered the most important reform of the BGB since its enactment, have dramatically changed German law. One of the most significant changes is in the field of impossibility. In fact, German lawmakers have almost rewritten the impossibility regime of the law. Within this scope, both the distinctions based on types of impossibility and the results of impossibility of performance have been amended.

    In 1999, the EC enacted three Directives, which were required to be transposed into German law. These were: the Consumer Sales Directive No. 1999/44/EC; the E-Commerce Directive No. 2000/31/EC and Late Payment Directive No. 2000/35/EC. The German legislator accepted such transposition as a chance to improve the reform proposal of 1992 in accordance with the Directives. The result was the Government Draft (Regierungsentwurf) of an Act to Modernize the Law of Obligations of May 9, 2001, which was approved by the German Parliament in July in its first reading. For a historical background of the reform, see Schlechtriem, German Act, p. 1 ff.

    The amendments include a reform of the provisions regarding impossibility of performance as well.

  7. 7.

    Zimmermann, New German Law, p. 40. According to Huber, the concept of “Pflichtverletzung” is identical to the term “non-performance” (which is recognized by the Unification Instruments). Author argues that the concept of non-performance is not appropriate for use in German law, since BGB has accepted fault-liability system. Huber, ZIP 2000, 2273, 2278 ff. For a critique of the term “Pflichtverletzung” and also “Nichterfüllung” (non-performance) as an alternative term, see Schwingenheuer, p. 44; Fikentscher/Heinemann, § 42 II, Nr. 361. For the conceptual difference between the terms, see Berghoff, p. 19 ff.

  11. 11.

    The logic behind the voidness of contracts due to initial impossibility was that in such cases the law assumed that the parties have made a mistake regarding ability to perform; hence the contract is not in uniformity with their free wills. In other words, parties would not conclude the contract should they be aware of the impossibility. Mitzkait, p. 210; Huber, Leistungsstörungen I, § 4 IV 2, p. 122, fn. 91. However, the former BGB did not limit voidness of the contract to the cases of mistake on initial impossibility. In other words, initial impossibility caused voidness of the contract regardless of the knowledge of the parties on the existence of initial impossibility at the time of contract formation. Mitzkait, p. 210. As a result, the distinction of initial and subsequent impossibility was highly criticized in the former BGB.

  12. 12.

    Lorenz, ELR 1997, 317, 327; Schwingenheuer, p. 43; Kaiser, ZfBR 2001, 147, 148. According to Mitzkait, in cases of impossibility § 275 BGB eliminates the debtor’s duty to perform regardless of his responsibility for impossibility. Therefore, once such duty is eliminated, it is a contradiction to base the creditor’s compensation claim to a breach of duty. Mitzkait, p. 249 ff.

  13. 13.

    Canaris argues that in the new BGB, the significance of the concept of impossibility has rather increased as an exemption from the obligation to perform the primary claim, but it has decreased as regard to claim for damages. Canaris, Schuldrechtsmodernisierung, p. XIII.

  14. 14.

    However, impossibility in technical and traditional sense falls under § 275/I BGB. Fikentscher/Heinemann, § 43 II 6, Nr. 402. In fact, the term “impossible” is only used in the first paragraph of the provision.

The term impossibility under § 275 I BGB corresponds to the cases termed as “echte Unmöglichkeit” or “wirkliche Unmöglichkeit”.

    Staudinger, Eckpfeiler, p. 309; Looschelders, Nr. 459; Fikentscher/Heinemann, § 43 II 2, Nr. 393; Palandt/Grüneberg, § 275, Rdnr. 18; Maile-Zinser, p. 16. The notion of performance under § 275 is not the act of performance, but the result of performance. In other words, if the performance would not yield any results, there exists impossibility even if the debtor can act to perform. BeckOK/Unberath, § 275, Rdnr. 41. However, such cases must be separated from frustration of purpose (Zweckstörung), where there is an impossibility of use (Verwendungsunmöglichkeit), since the creditor has no interest in performance as he cannot use the performance as intended. In fact, in cases where the impossibility of use occurs, the performance is still possible, despite being useless for the creditor. For instance, if a bride breaks up with the groom a short time before the wedding and the wedding gown that she ordered becomes useless, there is impossibility of use. Koller, § 53, Nr. 15; Looschelders, Nr. 460; Hütte/Helbron, Nr. 384; MüKo/Ernst, § 275, Rdnr. 160. For detailed information on frustration of purpose, see Köhler, p. 17 ff.

  23. 23.

    Former § 275/I BGB required debtor not be responsible for the occurrence of impossibility, otherwise he would not be released from his obligation to perform. Such provision was based on the Roman understanding that each obligation has a duplicate content: One party owes the primary claim and the other owes to make payment. Accordingly, it was argued that the debtor who is responsible for impossibility must not be relieved from his obligation to perform, otherwise the legal ground for the monetary compensation would disappear as well. Therefore the former § 275 I BGB accepted that the debtor’s obligation to perform would be extinguished only if he was not responsible for impossibility. In such case, the creditor would not ask for compensation instead, and therefore no legal ground would be necessary for compensation claim. However, if the debtor was responsible for impossibility, he would still be under the obligation to perform and this would enable the monetary compensation claim of the creditor. Fehre, p. 30.

    The former § 275 II BGB contained the same provision as well. However, the former distinction between subjective and objective impossibility was caused by the provision of the former § 306 BGB, which was applicable to objective impossibility only. Fehre, p. 23.

    For instance, see OLG Brandenburg, Urteil v. 31.07.2008 5 U 107/07 - JurionRS: “It is not necessary that the debtor, alone, cannot currently make dispositions on the subject of the obligation, in order to accept impossibility in terms of § 275 paragraph 1 BGB. It must be certain that the debtor can no longer obtain disposition on the subject of the obligation, in the future as well. The impediment must be almost insurmountable for the debtor. This can happen, for instance, in the case where the third party has definitely refused to participate in the performance.”

    Fehre, p. 24. “If the debtor gives the promised object to a third party, the performance is not automatically impossible for the debtor due to the fact that he cannot dispose on the object anymore and has no right of claim for it. However, if it is determined that the debtor cannot get his power of disposal back and cannot satisfy the claim raised for the object, impossibility occurs. As long as there is a possibility that third party grants the debtor the power of disposal again or consents to disposal, the inability for the debtor is not definite.” MDR 2006, 79, 80.

  34. 34.

    MüKo/Ernst, § 275, Rdnr. 51. However, such cases may lead to practical impossibility which is dealt with under § 275 II BGB. Fehre, p. 23; Barta, p. 14; Zimmer, NJW 2002, 1, 2. For a study on impossibility in obligation in kind, see Rohde, p. 1 ff.

  35. 35.

    According to Ernst, the debtor would be released from his primary obligation if the third party is regarded as absolutely untraceable. However, if there is reasonable possibility for reaching the third party, no such release would take place. In such cases, § 275 II BGB may apply, if there is gross disproportion between the expenses to be made by the debtor to trace the third party and the interest of the creditor. MüKo/Ernst, § 275 Rdnr. 52.

    Brox/Walker, § 22, Nr. 16. According to Canaris, the phrase “to the extent that” (soweit) covers temporary impossibility, in addition to partial impossibility. According to the author, any confusions regarding the scope of the provision could be avoided by inclusion of the phrase “as long as” (solange) in addition to the phrase “to the extent that” (soweit).

  50. 50.

    The burden of proof regarding the length of the term of impossibility is carried by the debtor. Gsell, p. 280.

  51. 51.

    Finn, p. 157. However, if the obstacle to the performance is surmountable, there exists no impossibility at all (not even temporarily). Finn, p. 158.

  52. 52.

    On the other hand, § 311a II BGB is relevant when the debtor is responsible. However, in such cases, the requirement of the debtor’s responsibility is not with regard to the occurrence of impossibility. In other words, the provision requires that the debtor knows the impossibility while concluding the contract or that the debtor is responsible for not knowing the impossibility. The provision reads as follows: “The obligee may, at his option, demand damages in lieu of performance or reimbursement of his expenses in the extent specified in section 284. This does not apply if the obligor was not aware of the obstacle to performance when entering into the contract and is also not responsible for his lack of awareness. Section 281 (1) sentences 2 and 3 and (5) apply with the necessary modifications.”

  53. 53.

    The provision eliminates the discussions regarding the time for the assessment of initial and subsequent impossibility. Accordingly, the time to be considered for such distinction is the time when the contract is entered into. Fehre, p. 25. This is also valid for contracts with condition and term. Fehre, p. 25; Palandt/Grüneberg, BGB, § 311a, Rdnr. 4.

  58. 58.

    If the contract is null and void for another reason (such as breach of a legal prohibition or immorality), § 311a BGB would not change such legal result. MüKo/Ernst, § 311a, Rdnr. 25; Fehre, p. 28; BeckOK/Gehrlein, § 311a, Rdnr. 4; Staudinger/Löwisch, § 311a, Rdnr. 56; Palandt/Grüneberg, § 311a, Rdnr. 5; Reasoning of BGB, Drucksache 14/6040, p. 165, available at <http://dipbt.bundestag.de/dip21/btd/14/060/1406040.pdf>.

  59. 59.

    As a result, the lawmakers have shifted the risk against the debtor. Since the contract is valid, the debtor would be obliged to compensate the creditor’s positive interest, in case of the responsibility of the debtor. Motsch, JZ 2001, 428, 430. However, the provision of § 311a I is in principle fully dispositive. The parties may accept in the contract that a specific impediment must not exist at the time of the formation of the contract, otherwise the debtor or the creditor would be entitled to revocation. MüKo/Ernst, § 311a, Rdnr. 102.

  60. 60.

    Fehre, p. 26.

  61. 61.

    Fehre, p. 26; MüKo/Ernst, § 311a, Rdnr. 2. In case of initial impossibility, the primary obligations of the parties are excluded. As a matter of fact, § 275 BGB eliminates the debtor’s obligation to perform and § 326/I eliminates the creditor’s counter-obligation. As a result, the contract lacks primary obligations of the parties. Brox/Walker, § 22, Nr. 11; Jauernig, § 311a, Rdnr. 4; BeckOK/Gehrlein, § 311a, Rdnr. 4; Fehre, p. 27; Fikentscher/Heinemann, § 43 II 1, Nr. 389; Staudinger, Eckpfeiler, p. 309; Reasoning of BGB, Drucksache 14/6040, p. 164, available at <http://dipbt.bundestag.de/dip21/btd/14/060/1406040.pdf>. However, since the contract is still valid, it still constitutes a basis for the secondary claims (Sekundäransprüche) of the parties. Canaris, JZ 2001, 499, 506; Fikentscher/Heinemann, § 43 II 1, Nr. 389. Moreover, since the contract is valid, the parties are bound with their side obligations (Nebenpflichten). Staudinger/Löwisch, § 311a, Rdnr. 21. Accordingly, if the debtor is responsible for the occurrence of impossibility, this creates an obligation to compensate the damages of the creditor. However, there are secondary claims which are available even in cases where the debtor is not responsible for impossibility. For instance, even if the debtor is not responsible for the occurrence of impossibility, the creditor is entitled to demand substitutes from the debtor. Fehre, p. 27; Reasoning of BGB, Drucksache 14/6040, p. 165, available at <http://dipbt.bundestag.de/dip21/btd/14/060/1406040.pdf>. If the contract were invalid, no substitutes could be claimed. The validity regime of § 311a BGB, which entitles the creditor to substitutes, enables the contract to fulfill its purpose. Fehre, p. 27. This is basically a result of the fact that in case of initial impossibility, a valid contractual relationship is established, but only the obligation to perform is eliminated. Staudinger/Löwisch, § 311a, Rdnr. 20.

    Staudinger/Löwisch, § 311a, Rdnr. 14. For information on the liability for initial inability, see Sutschet, NJW 2005, 1404, 1404 ff.; Hohmeister, p. 1 ff.

  65. 65.

    In case of limited debt in kind, impossibility occurs if the entire stock is destroyed. Looschelders, Nr. 289; Zerres, p. 135; Kötz, Nr. 793; Huguenin, Nr. 557; Bucher, p. 421.

  66. 66.

    Dural, Sonraki İmkansızlık, p. 138.

  67. 67.

    Unless there is limited debt in kind, objective real impossibility may occur if the subject-matter good is destroyed after the concretization of a particular piece of such kind. Within this stance, concretization refers to everything that the debtor must do as required by him for performance. Looschelders, Nr. 290; Hütte/Helbron, Nr. 97 ff. See § 243 II BGB: “If the obligor has done what is necessary on his part to supply such a thing, the obligation is restricted to that thing.” If there is not any concretization as well, then impossibility occurs only when the entire kind is destroyed. MüKo/Ernst, § 275, Rdnr. 34; Förster, Nr. 213; Blank, p. 48; Westermann/Bydlinski/Weber, § 7, Nr. 7/29 - 7/30; Dullinger, § 3, Nr. 3/52; Jousssen, Nr. 366; Zerres, p. 135; Hütte/Helbron, Nr. 385; Markesinis/Unberath/Johnston, p. 410. On the other hand, subjective real impossibility takes place when the debtor may have neither a thing of the kind, nor is it possible to obtain such a thing under any effort whatsoever. For instance, there is subjective real impossibility when the subject-matter good is available abroad, but the debtor cannot obtain such good due to an import ban. Mitzkait, p. 61. Such cases fall under § 275 BGB as well.

    It is argued that it may be difficult to distinguish § 275/I BGB from § 275 II BGB in case of subjective impossibility. Schlechtriem, German Act, p. 1 ff.; Zimmermann, New German Law, p. 47; Staudinger, Eckpfeiler, p. 310.

    Finn, p. 137. “Performance is objectively impossible and therefore cannot be demanded or enforced (§ 275 paragraph 1 BGB), if, under the laws of nature, or existing knowledge of science and technology it cannot be absolutely provided. It is so in case of the promise of using supernatural, ‘magical’ or psychic powers and abilities.” BGHZ 188, 71, 73. According to Fehre, sometimes the obligation arising from the contract may be nonsensical according to the views of third parties at the time of contract formation. For instance, an obligation to convert a car into an airplane by using magical powers is a nonsensical obligation. Similarly, an obligation to beam someone from one place to another might be accepted as a nonsensical one. It is quite difficult to concretize which obligations are nonsensical and which are sensible. Therefore, it would be more appropriate to accept that the contract is valid in accordance with § 311a/I BGB. In other words, in accordance with the intentions of the parties, the contract must be deemed valid. Fehre, p. 29.

    § 275 II BGB: “The obligor may refuse performance to the extent that performance requires expense and effort which, taking into account the subject matter of the obligation and the requirements of good faith, is grossly disproportionate to the interest in performance of the obligee. When it is determined what efforts may reasonably be required of the obligor, it must also be taken into account whether he is responsible for the obstacle to performance.”

    Opportunity costs are not taken into consideration within the scope of the assessment of required expenses and efforts. Opportunity costs are profits that could be acquired through other transactions that could be made by the debtor, if he had not concluded the contract with the creditor. The debtor cannot claim to be released from his duty to perform with an argument based on opportunity costs because when concluding the contract with the creditor, the debtor has already relinquished from other transactions which may bring profit.

    If these legal results are taken into consideration in comparison of interests, the creditor’s interest in performance would be comparatively higher, whenever he had no compensation claim against the debtor; because, when the creditor is entitled to compensation due to non-performance, this would decrease his interest in performance. In other words, the gap between the creditor’s interest and the required efforts and expenses of the debtor would be higher when the debtor is responsible for impossibility. As a result, it would be easier for the debtor, who is responsible for the obstacle to be released from his obligation to perform under § 275 II BGB. Fehre, p. 43; MüKo/Ernst, § 275, Rdnr. 81; Huber/Faust, Section 2, Nr. 31. On the other hand, when the debtor is not responsible for impossibility, since the creditor will not receive compensation due to non-performance, he would be better-off if the debtor performed. In other words, the creditor would have higher interest in performance. In such cases the disproportion between the creditor’s interest in performance and the debtor’s interest in non-performance would be lower. Therefore it would be harder for the debtor to rely on § 275 II BGB to be released from his obligation. This would contradict with the logic and also the intention of the lawmakers. Fehre, p. 43.

    Huber/Faust name this as absolute approach. Huber/Faust, Section 2, Nr. 43–44. On the other hand, relative approach considers how the proportion between the required expenses of the debtor and the creditor’s interest in performance has changed within time. Huber/Faust, Section 2, Nr. 43. In other words, according to the relative approach only the change is decisive. Within this context, there is disproportion if the proportion between the expenses and efforts of the debtor and the creditor’s interest in performance has changed against the benefit of one of the parties.

    In case of defective performance, § 439 I BGB entitles the buyer to “demand that the defect is remedied or a thing free of defects is supplied.” However, if the defect cannot be cured under § 275 I - III BGB, this constitutes qualitative impossibility (qualitative Unmöglichkeit). In case of qualitative impossibility, the debtor’s release from his obligation to perform may occur under any of the paragraphs of § 275 BGB, including paragraph 2. However, § 439 III BGB, which deals with defective goods, enables the seller’s release from his obligation under lower standards than § 275 II BGB. The said provision reads as follows: “Without prejudice to section 275 (2) and (3), the seller may refuse to provide the kind of cure chosen by the buyer, if this cure is possible only at disproportionate expense. In this connection, account must be taken in particular, without limitation, of the value of the thing when free of defects, the importance of the defect and the question as to whether recourse could be had to the alternative kind of cure without substantial detriment to the buyer. The claim of the buyer is restricted in this case to the alternative kind of cure; the right of the seller to refuse the alternative kind of cure too, subject to the requirements of sentence 1 above, is unaffected.” For a study on the competition between the rules of impossibility and the rules on defective performance, see Lehmann, Unmöglichkeit, p. 1 ff.

Accordingly, §§ 326 II, 446, 447, 616, 644, 645, 2380 BGB and § 56 I ZVG (Foreclosure Law) are examples of such exceptional provisions. In such cases, the creditor is obliged to perform the counter-obligation, even if he does not receive the performance of the debtor.

Therefore in such contracts, when the first obligation becomes impossible to perform, the second obligation does not come to existence at all. As a result, in such contracts, there is no room to apply the provision.

  184. 184.

    § 326 I sets forth that “in the case of part performance, section 441 (3) applies with the necessary modifications.” § 441 III reads as follows: “In the case of a price reduction, the purchase price is to be reduced in the proportion in which the value of the thing free of defects would, at the time when the contract was entered into, have had to the actual value. To the extent necessary, the price reduction is to be established by appraisal.”

  185. 185.

    MüKo/Ernst, § 326, Rdnr. 18. Such provision regarding partial impossibility would also apply to temporary impossibility. This means that as long as temporary impossibility exists, the creditor is entitled not to perform the counter-obligation. Provided that the creditor loses his interest in the performance in case of delay, the creditor is also entitled to terminate the contract. Reasoning of BGB, Drucksache 14/6040, p. 189, available at <http://dipbt.bundestag.de/dip21/btd/14/060/1406040.pdf>.

B 40; Reasoning of BGB, Drucksache 14/6040, p. 188, available at <http://dipbt.bundestag.de/dip21/btd/14/060/1406040.pdf>. However, it must be underlined that such loss of interest does not cause partial impossibility revert into full impossibility. This means that the creditor’s obligation is not extinguished ipso iure, and the counter-obligation is not fully eliminated. In case of loss of interest in partial performance, the creditor is given a right to revoke the contract. This might then end up in full extinguishment of the obligations of both parties. Wieser, MDR 2002, 858, 861. According to Ernst, in such cases the debtor does not have the right of revocation, since partial impossibility has affected the performance of the debtor. Hence the debtor must bear its consequences in the first place. MüKo/Ernst, § 326, Rdnr. 25.

  187. 187.

    However, an application of § 441 III requires that the counter-obligation is divisible; otherwise the provision would not apply. MüKo/Ernst, § 326, Rdnr. 28. If performance is indivisible in nature, partial impossibility would be deemed to be equivalent to full impossibility. Emmerich, § 10, Nr. 32; Staudinger/Otto, § 326, Nr. B 40.

    Since such obligation of the claimant has become impossible within the meaning of § 275 BGB, in principle, as compensation, the claimant owes according to the leasing contract, the surrogate of the amortization or transfer on account of performance of the claim on the insurance claim assigned to the defendant.” AG Hamburg-Altona, Urteil v. 11.08.2004 319B C 79/04 - JurionRS.

    Emmerich, § 10, Nr. 19; Mitzkait, p. 117. § 285 BGB sets fort that the substitute of the “object owed” may be demanded by the creditor. Therefore, it is argued that the provision would not apply when the debtor is released from his obligation due to moral impossibility because in such cases the subject matter of the obligation is not an object but services. BeckOK/Unberath, § 285, Rdnr. 7.

    Palandt/Grüneberg, § 285, Rdnr. 7; Staudinger/Löwisch, § 285, Rdnr. 30. § 285 II further sets forth that “If the obligee may demand damages in lieu of performance, then, if he exercises the right stipulated in subsection (1) above, the damages are reduced by the value of the reimbursement or the claim to reimbursement he has obtained.” This prevents the enrichment of the creditor at the expense of the debtor. Emmerich, § 10, Nr. 23.

  228. 228.

    Palandt/Grüneberg, § 285, Rdnr. 8. If impossibility is caused by the damage or destruction of the raw material that is required for the subject matter of the contract, § 285 I BGB would not apply. Similarly, § 285 I BGB is excluded when the leased property is destroyed because in such cases the lessor is under an obligation to leave the leased property to the lessee only for use. However, the compensation received by the lessor from the third party is given due to the destruction of the good and it pertains to the total value of the leased property. Emmerich, § 10, Nr. 21.

According to the value judgment of the law, the creditor can, instead, reclaim the substitute, when it has a higher value than the provided performance.” AG Hamburg-Altona, Urteil v. 11.08.2004 319B C 79/04 – JurionRS.

    This provision regulates the return of what has been performed before extinguishment of the counter-obligation.

    Emmerich, § 10, Nr. 27. In the former BGB, initial impossibility was a reason of voidness of the contract. Therefore in such cases there existed no contract that could be revoked.

  251. 251.

    Dörner/Staudinger, p. 38; Rüssmann, p. 285. According to Emmerich, such amendment has importance only in limited cases because in cases where the debtor has no responsibility for impossibility, § 326 I BGB releases the creditor from his counter-obligation. Therefore there would generally be no need for the creditor to revoke the contract. Emmerich, § 10, Nr. 28.

    § 323 I reads as follows: “If, in the case of a reciprocal contract, the obligor does not render an act of performance which is due, or does not render it in conformity with the contract, then the obligee may revoke the contract, if he has specified, without result, an additional period for performance or cure.”

Since § 326/V BGB makes reference to § 323 BGB, a valid revocation requires the breach of contract, namely the defect, not being trivial. Fikentscher/Heinemann, § 43 IV 4, Nr. 457.

    As explained above, the burden of proof can be derived from § 280 I s. 2 BGB.

  262. 262.

    According to Fikentscher/Heinemann, although it is not explicit in the BGB, § 283 applies solely to subsequent impossibility because compensation of damages has been specially regulated under § 311a II BGB for the cases of initial impossibility. Fikentscher/Heinemann, § 43 III 3, Nr. 419.

  263. 263.

    The second, third and fourth paragraphs of § 281 deal with setting a period of time (Fristsetzung) prior to claiming damages so that the debtor can perform. However, these provisions are inapplicable to cases, which fall under § 275 BGB. In fact, in such cases, either there is impossibility that the debtor cannot perform, or he cannot be expected to perform due to gross disproportionality or personal reasons. In all cases, it is clear that setting a period of time would not result in performance. Medicus, Nr. 386; Fikentscher/Heinemann, § 43 III 3, Nr. 420; Brox/Walker, § 22, Nr. 56; MDR 2006, 858, 858.

  264. 264.

    According to the § 281 V: “If the obligee demands damages in lieu of complete performance, the obligor is entitled to claim the return of his performance under sections 346 to 348.” This shows that the creditor cannot rely on the provisions of unjust enrichment (§ 818 f.). Medicus, Nr. 387.

According to Koller, in case of subsequent impossibility for which the debtor is responsible, the creditor has a right to choose between his negative or positive interest.

If it can be argued that the creditor was aware of initial impossibility or he must have been aware of it, this constitutes contributory negligence (Mitverschulden). Therefore, the compensation to be paid to the creditor would be reduced proportionally with his fault (in accordance with § 254 BGB) and then the counter-obligation that he would perform under § 326 II would be offset. Fikentscher/Heinemann, § 43 III 2, Nr. 412.

  277. 277.

    According to Popescu, dogmatically the liability of the debtor under § 311a II cannot be positive interest. The author argues that positive damages may only be compensated under § 311a II if the debtor already knew the existence of an impediment that can be overcome. Popescu, p. 135–135.

In fact, § 311a II functions as an explicit provision, which enables the positive interest claims of the debtor. Otherwise the creditor could only claim his negative damages based on culpa in contrahendo. Schlechtriem, Unmöglichkeit, p. 131. According to Canaris, there is a warranty in the promise of the debtor. Canaris, Grundlagen, p. 35.

Hirse rejects such opinion since the option of claiming compensation based on culpa in contrahendo is already theoretically available. Hirse, in: Tonner/Willingmann/Tamm, § 311a, Rdnr 13. Similarly, Dauner/Lieb reject the option of analogy to § 122 BGB, since there is not a gap in the law. Dauner/Lieb, in: Dauner-Lieb/Heidel/Lepa/Ring, Schuldrecht, § 311a, Rdnr. 18.

    Looschelders, Nr. 683. According to Fikentscher/Heinemann, rather than as an alternative to positive damages, reimbursement of futile expenses must have been designated as a cumulative remedy. Authors think that there is a construction mistake with regard to § 284 BGB. Fikentscher/Heinemann, § 43 III 4, Nr. 440.

    Prior to the reform of 2002, to ease such difficulty of proof, the courts have applied a presumption of profitability (Rentabilitätsvermutung). Accordingly, it was presumed that the expenses made by one party for the performance of the contract are first palpable damages (ersten handgreiflichen Schaden). Therefore, even if the creditor cannot prove his lost profit, he can at least cover his expenses. However, this presumption applies only if the creditor has concluded the contract with a purpose of making profit. Unlike the presumption of profitability, the new provision of § 284 BGB does not require that the creditor has the purpose of making profit. Medicus, Nr. 388; Looschelders, Nr. 675–676; Brox/Walker, § 22, Nr. 72; Dedek, in: Henssler/Graf von Westphalen, § 284, Rdnr. 1; Willingmann/Hirse, in: Kohte/Micklitz/Rott/Tonner/Willingmann, § 284, Rdnr. 1; Hk-BGB/Schulze, § 284, Rdnr. 2; Dauner-Lieb, in: Dauner-Lieb/Langen, § 281, Rdnr. 64.

    In this opinion, see Canaris, DB 2001, 1815, 1816. Peres argues that compensation claim arising from culpa in contrahendo and § 311a II are concurring claims. Peres, p. 55. According to Fehre, in addition to the claim based on § 311a II, a claim based on culpa in contrahendo may also be possible, when the debtor has failed to immediately inform the creditor about the impediment to the performance.
