The first reactions after the outbreak of the Greek financial crisis were pension reforms and pension cuts. The central concern of this book is to present a legal framework that allows pensioners to assert claims in court. The book provides an overview of the background to the factors that made pension reforms necessary before and after the financial crisis. It also describes the pension reforms and individual cuts in pension benefits gradually implemented by the Greek Parliament from the beginning of the crisis to 2012. Finally, it addresses the compatibility of state pension reforms and pension benefit cuts with the Greek Constitution and international law.
