For almost 30 years, Judge Mark Wolf’s courtroom has been ground zero for some of the state’s most notorious cases. 

One of his early rulings in the Whitey Bulger case led to congressional hearings about the FBI’s use of murderers as informants, he oversaw the trial of former house speaker Sal DiMasi, and he’s made several controversial rulings in the case of convicted transgender murderer Michelle Kosilek.

Now he’s taking his ideas to a bigger arena. Judge Wolf will appear before a Capitol Hill human rights commission to propose an international anti-corruption court. Citing nations like Somalia, Afghanistan, Syria and Sudan, proponents of the court say corruption is the single biggest obstacle to human rights in the world.
