Ziobro graduated from the Faculty of Law and Administration of Jagiellonian University. He did not complete his PhD. He was a member of the Sejm from 2001-2005.
Due to his proclaimed "battle against corruption", he became one of the more popular, but also polarizing, politicians in Poland. His uncompromising approach and publicized prosecutions earned him the title Man of the year 2006, awarded by Wprost magazine. However, some of his policies were repeatedly characterized as partisan and overzealous by local and international press, including The Economist.
