Lacey said Brown failed to provide "credible, competent or verifiable evidence" that he completed his court-ordered community labor that he was required to do for beating Rihanna in February 2009.
The R&B singer was ordered in August 2009 to complete 180 days of community labor and was allowed to do it in his home state of Virginia as part of a five-year probationary sentence. He had pleaded guilty in June 2009 to one felony count of assault by means of force likely to produce great bodily injury.
According to a motion filed by the L.A. County District Attorney's Office, the court was asked to decline Brown's community labor from Virginia due to what appeared to be "significant discrepancies indicating at best sloppy documentation and at worst fraudulent reporting."
"Chris didn't violate anything. The DA should be ashamed of themselves. They besmirched the reputation of Chris Brown based on no evidence," said Brown's attorney Mark Geragos. "It is defamatory, scurrilous, and we will address it in the court room."
The motion said investigators traveled to Virginia to verify that Brown had worked all the hours as reported by the Richmond Police Department, but they were unable to confirm it. It also said Brown was essentially unsupervised during his community labor.
Richmond Police spokesman Gene Lepley said in a brief statement, "It would be inappropriate to comment on a matter before the court."
Brown is scheduled to be in court on Wednesday afternoon for a probation violation hearing.
