Williams frequently found himself in trouble with umpires and had many tribunal appearances – often as the result of overzealous retaliation against his taggers. He was charged a total of 19 times, found guilty 12 times, and suspended for a total of 34 matches during his career. He was also known for his generally impolite treatment of umpires, and the Tribunal found him guilty of verbally abusing an umpire on three occasions, for which he was twice fined and once suspended.
