In 2006, Romanian President Traian Băsescu appointed him head of the Presidential Commission for the Study of the Communist Dictatorship in Romania, which presented its report to the Romanian Parliament in December of that year. As of 2009, Tismăneanu is also Chairman of the Academic Board, Institute of People's Studies—an institution affiliated with the Democratic Liberal Party, which in turn is the main political group supportive of Băsescu's policies. The institution is presided upon by political scientist Andrei Țăranu. The following year, Tismăneanu was chosen by Democratic Liberal Premier Emil Boc to lead, with Ioan Stanomir, the Institute for the Investigation of Communist Crimes in Romania, substituting the National Liberal Party's choice Marius Oprea. Tismăneanu was dismissed by the newly formed Victor Ponta government in May 2012.
