Ja Rule's bid to have the discovery of a loaded gun in his car not used against him in court has been rejected.
Manhattan state Supreme Court Justice Richard Carruthers rejected the platinum-selling artist's argument that the gun was found during an unjustified police stop of his Maybach sports car after a July 2007 concert.
His lawyer said outside court she disagreed with the judge's decision and would pursue other avenues to fight the charges he faces in the weapons possession case.
Prosecutors said the traffic stop was proper because the chauffeured car was speeding and had a suspended registration and no insurance.
The star's lawyer claimed authorities were looking for reasons to pull over Ja Rule and other rappers after the show, a claim prosecutors denied.
After stopping the luxury car, police said they smelled marijuana and found a .40-caliber semiautomatic gun in the rear driver's side door.
Carruthers threw out the rapper's statement to police that he had "a little bit of weed" in his pocket. He isn't charged with drug possession.
If convicted, the 33-year-old faces up to four years in prison.
