Special Order 7 allowed unlicensed drivers stopped by police to produce registration, valid ID and proof of insurance to avoid having their cars impounded.
Beck issued the directive Friday, telling officers not to adhere to Special Order 7 until further notice.
He, however, expressed disappointment in the Superior Court judge's decision and says it undermines the LAPD's authority to direct the conduct of its officers.
"I am dissapointed in this court's decision and believe it inappropriately undermines the Police Department's authority to lawfully direct the conduct of its officers," Beck said in a statement. "I look forward to the next phase of the judicial process."
It remains unclear if the city will appeal the court ruling.
Immigrant rights groups are expected to appeal. They say seizing and impounding the vehicles of immigrants who can't obtain driver's licenses is unfair.
