[4] After the fall of the Eastern Bloc, Polák openly founded numerous anarchist organizations and publications.
[2] In 1991, Polák and others from ČAS founded the A-Kontra magazine, which became the central organ of the Czech anarchist movement in the 1990s and early 2000s.
He worked as "attorney-in-fact" with numerous victims of racist and neo-Nazi attacks, including in the case of Tibor Danihel, a victim of a 1993 attack by racist skinheads in Písek, South Bohemia,[3] which he eventually brought to the Czech Supreme Court.
[2] Polák was himself attacked in August, 1999, in a restaurant in Karvina, where he was meeting government minister Jana Chalupova regarding a 1998 skinhead murder of a Romani.
Even in the last months of his life, while ill with cancer, Polák worked with Roma people in a case[3] involving their eviction and relocation from their home in Přednádraží, a neighborhood (sometimes described as a ghetto or shantytown) in Ostrava-Privoz.
