SACRAMENTO, Calif. (AP) — A Sacramento County judge will hear arguments over whether former Gov. Arnold Schwarzenegger violated California law when he reduced the prison sentence for the son of a political ally.

San Diego’s district attorney and the family of slain 22-year-old Luis Santos say Schwarzenegger violated the voter-approved Marsy’s law because he didn’t notify the family or district attorney that he was considering a commutation.
