The core principle of the German Basic Law - the Constitution of the Federal Republic of Germany since 1949 - is the Rule of Law or the broader concept of the 'Rechtsstaat'. The protection of fundamental rights is one important cornerstone of this principle. As the guardian of the Constitution, the Federal Constitutional Court has shaped these rights through interpretation by a large body of case law. Taking note of the growing interest among scholars not only in continental Europe but more so in the Common Law world, an extensive English translation of that jurisprudence is very timely.
