Scottie Pippen -- Off The Hook for Malibu Sushi Beatdown

Chalk up ANOTHER victory for Scottie Pippen ... TMZ has learned the retired NBA superstar will NOT be prosecuted for kicking a guy's ass outside of a Malibu sushi joint back in June.

The L.A. County D.A. determined there was simply not enough evidence to prove Scottie did anything wrong during a confrontation with 49-year-old Camran Shafighi outside of Nobu on June 23.

According to official documents, obtained by TMZ, Pippen -- who's now represented by mega-attorney Mark Geragos -- admitted pushing and spitting at Shafighi but officials determined it was impossible to tell if Pippen was the aggressor or if he was acting in self-defense.

Plus, officials concluded the victim was FAKING multiple injuries -- and even faked seizures -- in an effort to make Pippen look like the bad guy.

According to the document, doctors believe Shafighi's injuries were minor at best and included a cut to his lip and a bruised chin.

TMZ broke the story ... the two scuffled in the parking lot of the restaurant after Scottie refused to pose for a SECOND picture with Shafighi.

Officials claim Shafighi was extremely intoxicated at the time of the confrontation (.18 blood alcohol level) ... and also tested positive for opiates.

Shafighi can still go after Pippen in civil court -- he's already filed a $4 million suit -- but this is a pretty big blow to his case.
