I was just informed of a criminal case here in Oklahoma wherein the defendant accepted a plea bargain from the prosecution only to have the prosecution come back later with additional criminal charges for the same crime? Is this legal? Does anyone know of any case laws or common laws that have been violated in this area? Where do I find laws governing the prosecution in their offering of pleas? Any help would be greatly appreciated as I know this is something I'm going to have to be researching.
