The Situation scored a major legal victory over a company that hired him to promote their anti-fat cream, but then sued him for reneging his duties and hiding an RX drug addiction ... TMZ has learned.
According to court docs ... the "Jersey Shore" star and a company called Performance Brands both agreed to dismiss their dueling lawsuits (Sitch had filed a counter suit) after settling out of court.
Sources close to Sitch tell us ... PB agreed to cough up a "good sum of money," and Sitch won't have to shell out a dime.
TMZ broke the story ... PB sued Sitch after they hired him to be the face of their fat-metabolizing cream (and forked over a $75k advance) -- claiming he did ZILCH to promote the product. The company also claimed he breached his contract by hiding his RX addiction.
Sitch counter-sued, claiming PB was the one in breach of contract.
The case was dismissed earlier this month.
