An appeals court rejected a request by lawyers for the man accused of shooting former Rep. Gabrielle Giffords to rehear their arguments over their mentally ill client's forced medication with psychotropic drugs.

Attorneys for Jared Lee Loughner had asked the 9th U.S. Circuit Court of Appeals for a rehearing after the court in March denied their request to halt their client's forced medication.

The court on Tuesday denied the request to hear the appeal again.

Loughner has pleaded not guilty to 49 charges stemming from the January 2011 shooting in Tucson that killed six people and wounded former U.S. Rep. Gabrielle Giffords and 12 others.

The trial court judge on the case has set a June 27 hearing in Tucson to consider whether Loughner is mentally fit to stand trial.
