Pamela Smart's lawyers are challenging her murder conviction over the 1990 killing of her husband, Gregory Smart, arguing in a new legal filing that she "did not receive the fair trial that she was due." In a petition for writ of habeas corpus filed Monday, January 5 and viewed by Us Weekly, Pamela's lawyers wrote that Smart's constitutional rights were denied during her trial, in which they said several errors were made. "Pamela Smart's case was subjected to a type of media scrutiny that the world had never seen....It was a trial by media in the purest form," the petition stated, in part.
