Getting busted by cops caught up in the ticket-fixing probe will not mean an automatic “get out of jail free” for defendants.

A Bronx judge yesterday ruled against a former prosecutor who wanted his DWI case tossed because the arresting officer admitted she made traffic tickets disappear for her mom and boyfriend’s cousin.

The ruling sets a precedent that could salvage thousands of criminal cases jeopardized by the NYPD ticket-fixing scandal.

Internal Affairs cops are probing up to 500 cops for possible administrative violations, and a Bronx grand jury may file criminal charges against 40 or more others.

“This is going to be an important decision for a lot of cases,” one Bronx prosecutor said.

Bronx Supreme Court Judge James Kindler denied a motion from former Assistant District Attorney Stephen Lopresti to have the felony charge dismissed because Officer Julissa Goris, 29, admitted contacting her PBA rep to get the tickets dismissed.

“The Court finds the hearing testimony of Police Officer Goris to be credible,” Kindler wrote. “The so-called ‘fixing’ of traffic summonses is a serious matter that should be — and is being — investigated by the proper authorities.”

Lopresti, who has three prior misdemeanor convictions for driving under the influence, was arrested after an accident on Grand Concourse in December 2006.

During a hearing on Lopresti’s motion, Goris admitted she called union rep Jaime Payan to get him to fix a ticket for her boyfriend’s cousin.

The call was picked up on a wiretap.
