Controversies
In 2009, Michalik was linked to case of relegation of a policeman who gave him a speeding ticket. On February 15, 2007 Michalik, in an interview with Polish TV, Polish Press Agency PAP, IAR and the IAC, has reported that the Church Historical Commission on the basis of materials established by the Institute of National Remembrance IPN found that during the years 1975 to 1978 he was registered as an agent of the Communist secret police codenamed "Zephyr". The commission on the basis of available materials also recognized that there is no basis to determine the nature of his actual work. In 2013, responding to reports of a succession of child sex abuse scandals, Michalik said "Often that inappropriate approach or abuse is released when the child is looking for love. It clings, it seeks. It loses itself and also draws in that second person." This comment was heavily criticised, and Michalik called a news conference to apologise, stating that he did not blame children who were victims of abuse. In October 2013 Michalik's online biography was discovered to contain an incorrect claim of an award granted by Cambridge University.
