Luis Resto was prosecuted after his fight with Billy Collins jr. The incident is well documented; Resto was found guilty of assault.
That's not an intentional foul, Resto walked in the ring with tampered equipment, i think that's assult with a deadly weapon.
As for the TS, If Golota didn't get sued, and those were some of the most flagrant fouls ever, then i doubt it.
the Butler case is different because he hit grant without gloves on and not in the course of competition. But normally no, there can be no suits or charges levied for intentional fouls unless they are particularly outrageous and are not foreseeable results of participating in a boxing match.
i'm not sure about the civil matters (if money was given to the damaged party)
but i remember when richard grant got his toung chopped in half when he was sucker punched at the end of a fight on ESPN
the guy who hit him had his license revoked
and went to prison
he later killed the brother of max kellerman with a hammer
