Reijer Passchier is a PhD researcher and junior lecturer at the department of Constitutional and Administrative Law at Leiden Law School. In the spring of 2014, he was a visiting researcher at the department of Government of the University of Texas at Austin. Reijer’s thesis concerns the triggers and effects of ‘silent constitutional change’, i.e. constitutional transformations that occur independently from a formal amendment procedure. His case studies center around topical constitutional developments in the United States, Japan, Germany and the Netherlands. The comparative study is funded by the Netherlands Organization for Scientific Research (NWO) and supervised by Professor Wim Voermans and dr. Marga Groothuis. Reijer is also interested in constitutional design and legislative studies. He was nominated for the Leiden Law School JSVO teaching award 2013-2014.
