A federal appeals court will hear arguments Tuesday on requests from attorneys for the Tucson, Ariz., shooting rampage suspect to halt their mentally ill client's forced medication with psychotropic drugs and rescind his stay at a Missouri prison facility.

Jared Lee Loughner's lawyers have asked the 9th U.S. Circuit Court of Appeals to end their client's commitment at the prison in Springfield, Mo., where mental health experts are trying to make him psychologically fit to stand trial.

Loughner has been treated for his mental illness in Missouri after U.S. District Judge Larry Burns in May declared him mentally unfit to stand trial.

However, Burns ruled in late September that it's probable the 23-year-old can be made fit for trial, and ordered that Loughner's four-month stay in Missouri be extended by another four months.

Loughner has pleaded not guilty to 49 charges stemming from the Jan. 8 shooting in Tucson that killed six people and injured U.S. Rep. Gabrielle Giffords and 12 others.
