Gerhard Robbers is one of the most distinguished scholars in the field of constitutional law on religion in Europe. At the same time, he dedicates himself to several other legal topics. On the occasion of his 70th birthday and in order to honour him as teacher, scholar and practitioner, the “Festschrift” brings together contributions covering his fields of work: State and religion, fundamental questions of state government, constitutional law, European Union law,fundamental and human rights as well as legal policy. The 61 contributions are written in German and English, and address both basic as well as highly topical legal problems. The “Festschrift” has a clear focus on State and religion from a national, comparative and European perspective. This way, it constitutes one of the most comprehensive works in this broad field of law.
