WASHINGTON (AP) - Lawyers for singer Chris Brown are headed back to court in Washington, but the Grammy winner won't be there.
    
Brown's trial on a misdemeanor assault charge is currently set for April 17. On Monday, his lawyers and a government prosecutor will be in court for a motions hearing. Brown's lawyers have asked a judge to dismiss the case, saying prosecutors misused the grand jury process to prepare for trial. They also want certain statements Brown made suppressed.
    
A government prosecutor, meanwhile, is asking the judge to bar Brown from claiming self-defense or introducing evidence of mental health issues.
    
Brown and his bodyguard were arrested in Washington in October and are accused of punching a man outside a Washington hotel.
    
Brown's case will be heard by a judge, not a jury.
