​A Battle Creek, Michigan man who was fired a year ago for legally using medical marijuana is fighting Wal-Mart’s attempt to move his lawsuit to federal court.

Battle Creek Enquirer. Casias, a 30-year-old cancer patient and former Employee of the Year, was A federal judge on Friday will hear arguments in the lawsuit of Joseph Casias, reports the. Casias, a 30-year-old cancer patient and former Employee of the Year, was fired by Wal-Mart after a routine drug screen found he had used cannabis.

Casias was legally registered in Michigan to use marijuana to treat pain.

Casias, 30, did not use marijuana at work or work under the influence, his attorneys said.

Casias’s attorneys will ask the court to deny a motion filed by Wal-Mart seeking dismissal of the case and reject the mega-corporation’s attempt to have the case tried in federal court instead of state court.

The case was originally filed in Calhoun County Circuit Court in June.

Casias’s firing violates the Michigan Medical Marihuana Act, which reads in part that a qualifying patient shall not be “denied any right or privilege, including but not limited to … disciplinary action by a business or occupational or professional licensing board of bureau, for the medical use of marihuana.” Under the law, the definition of “medical use” contains “internal possession” — having marijuana in one’s system.
