GRAND RAPIDS (AP) -- A federal judge in Michigan has heard arguments in the case of a medical marijuana user claiming a Walmart store wrongfully fired him after testing positive for the drug.
U.S. District Judge Robert Jonker in Grand Rapids is considering a motion by attorneys representing Joseph Casias to move the case back to state court and Wal-Mart Stores Inc.'s motion to dismiss the case.
Bentonville, Ark.-based Wal-Mart says it's sympathetic to Casias' condition but wants the case in federal court.
Casias was fired last year after five years working in Battle Creek. He says he was registered to use the drug to treat symptoms of an inoperable brain tumor and cancer.
Michigan voters approved medical marijuana use in 2008.
