This chapter examines the jurisprudence of national courts on crisis-related measures. The material presented in this chapter will be divided into two parts. First, this chapter will examine some of the most important judgments delivered by courts in lender states during the Euro crisis, the emphasis being on the jurisprudence of the German Federal Constitutional Court. These cases primarily focus on the effects of financial assistance mechanisms and revised EU fiscal governance rules on the principle of democracy, parliamentary prerogatives, and national budgetary powers. A further strand of case law focuses on the measures adopted by the European Central Bank. Second, this chapter will look at review by national courts in borrower states, the principal focus being on social challenges brought by austerity-hit litigants in Greece. The comparative analysis sheds light on the different types of challenge facing courts in borrower and lender states, as well as the different starting points and the subtle differences in the reasoning provided by courts in their judgments. As regards borrower states in particular, the twin challenge is to examine to what extent litigants had any success in challenging in national courts the bailout conditions; and the extent to which arguments about civil or socio-economic rights had purchase at national level. The chapter further looks at review by national courts in other jurisdictions, as well as review by supranational and international courts or bodies. Last, it puts forward a number of ideas on fundamental rights adjudication in times of economic crisis.
