About this book
This book moves from the circumstance whereby currently the obligation to provide
fair and equitable treatment (FET) to foreign investments is included in the majority of
international investment agreements and has proved to be the most invoked standard in
investor-State arbitration. Hence, it is no overstatement to describe this standard as the
basic norm of international investment law. Yet both its meaning and normative basiscontinue to be shrouded in ambiguity and, as a consequence, to inspire a considerable
number of interpretations by legal writers. The book’s precise aim is to unravel such
ambiguity, arguing from the idea that FET has become part of the fabric of general international
law, but has done so by means of a source somewhat neglected in legal doctrine.
This being the category of general principles peculiar to a certain field of internationallaw, i.e. those principles having their own foundations in the international legal order
itself, but which, through the mediation of the judge, end up being shaped according
to the features typical of a specific normative field. The book, as well as having a solid
theoretical backdrop as its basis, offers a careful and critical analysis of pertinent case
law, and will prove useful to both scholars and practitioners.
