This summer, the initiative on “Constitutionalism Under Stress,” part of the Princeton-Humboldt Universität zu Berlin Strategic Partnership, concluded another successful seminar and workshop in Berlin. Ten Princeton graduate students, including eight from the Politics Department, joined peers in Berlin for an intense interdisciplinary seminar – including perspectives from law, political theory, history, and the social sciences – devoted to the topic of separation of powers.  The course was taught by Politics professor Jan-Werner Müller, Sociology professor Kim Lane Scheppele, from the Princeton side, and law professor Anna-Bettina Kaiser and comparative politics professor Silvia von Steinsdorff from Humboldt.  Also in attendance was Andrew Weissmann ‘80, former lead prosecutor in Robert S. Mueller’s Special Counsel’s Office; Weissmann debated recent developments in the US with Kim Scheppele, as part of a public forum held on the first day of the seminar.  The two-day workshop on separation of powers brought together scholars from Germany and the US; several Politics graduate students also presented their work to a distinguished audience which included two former justices of the German constitutional court.  The cooperation continues to be administered by the Politics Department; from this year onwards, it will majorly financed by PLANT, part of the Center for Human Values and directed by Kim Scheppele.
