Florida Supreme Court justices have disciplined seven South Florida lawyers since March 21, issuing three suspensions, three disciplinary revocations and a permanent disbarment, according to information released Tuesday.

Miami Beach attorney Peter Milan Predrag Vujin has permanently lost his license after allegedly threatening the opposing party in a civil case with criminal action to gain a competitive edge. According to the referee's findings, Vujin sent an unfounded presuit demand seeking $9,000 plus $4,000 in attorney fees, claiming the recipient would “most likely face deportation for your obvious commission of several aggravated felonies.”

Vujin, who was admitted to the bar in 2003, is accused of misrepresenting what happened. He has previously been disciplined for similar conduct. Vujin disputed the accusations, claiming he'd blown the whistle on a fraudulent scheme. He said he's seeking legal recourse in federal court.
