George Mátsik (Szombathely 11 November, 1925-Budapest December, 2017) Attorney, and HEN Trust CEO. He gained more prominence in the Mansfeld trial.
He worked in the Supreme Public Prosecutor's Office. In 1957 he obtained a legal degree from 1968 worked in the prosecutor's body until the end.
During the retaliation following the 1956 War of Independence and the Revolution, it has been proven that he was involved in the prosecuting and sentencing of at least 27 prisoners to death. Typically, he represented the accusations in criminal proceedings against public figures and non-politically important persons. As a prosecutor serving unrestricted dictatorship, in a lawsuit against Peter Mansfeld, who was a minor, and his associates, argued that it is irrelevant to political or anti-state offenses whether the offender is an adult or a minor.
At the end of 1968 he was assigned to the Head of Department at the Budapest University of Agriculture.
No account was taken of responsibility after the change of regime. In July 2012, two MPs, Levente Murányi and György Szilágyi, László Mansfeld, brother of the late Péter Mansfeld, and the Hungarian Political Prisoners Association declared György Mátsik of more deliberate homicide, more deliberate serious bodily harassment, more orderly abductions, more abusive forced abductions, more misconduct, more illegitimate renditions detention and multiple crimes. In its decision of 6 September, the Central Prosecutor General's Office refused to report in the absence of a crime.
