APPROACH AND METHOD
This is not a technical book on sunset clauses and experimental legislation. Instead, this is a comparative law study that reflects on the framework, potentialities and constitutional limits of these legislative instruments. These legislative instruments are nowadays enacted in diverse Western jurisdictions, notably Germany, the Netherlands, the United States, Spain, the United Kingdom, France and Switzerland, and even at the EU level. For the purposes of this study, the United States, the Netherlands and Germany have been selected. These jurisdictions were selected since, on the one hand, in all of them experimental legislation and sunset clauses have been enacted in the last decades - though under different designations. On the other, these jurisdictions have different experiences with their implementation. In none of these jurisdictions is there a clear framework for the enactment and implementation of sunset clauses and experimental legislation. There is thus room for learning in the three countries. An introductory overview of these jurisdictions is provided here.
