Tadić was arrested by German police in Munich in 1994. He faced twelve counts of crimes against humanity, twelve counts of grave breaches of the Geneva Conventions, and ten counts of violations of the customs of war, to all of which he pleaded not guilty. His trial was to be held together with Goran Borovnica's, but Borovnica went missing in 1995 and was later declared dead.
Tadić was found guilty on 13 of the charges for crimes against humanity and violations of the laws of war. He was sentenced to twenty years imprisonment. Upon Tadić's appeal of the ruling, he was found guilty of several more charges. He is currently serving his sentence in Germany.
