Sally Challen [2019] EWCA Crim 916

The appellant was convicted of murder after her plea to manslaughter on the basis of diminished responsibility was rejected. The principal issue at trial was diminished responsibility and provocation was not argued. She appealed on the basis of fresh evidence on coercive control and fresh psychiatric evidence to support the proposition that at the time she was suffering from an abnormality of mind. The fresh evidence also went to the issue of provocation. The murder conviction was quashed.
