Whether battered spouse syndrome should be a defense in criminal cases has been a controversial issue for many years. Since 1991, a Maryland statute has made such evidence admissible to prove the defendant’s motive or state of mind at the time of the alleged crime. Whether this defense may be available even where the battered spouse hired someone to kill her husband was addressed by a divided Maryland Court of Appeals this week in a case called Karla Louise Porter v. State of Maryland.
Judge Adkins’ opinion for the 4-3 majority indicates a long history of physical and verbal abuse by the defendant’s husband toward her. The defendant testified at trial that eventually she concluded that she knew her husband was going to kill her and she wanted to kill him first. She approached several, eventually hiring someone to kill him at their place of business, with the defendant calling the police to make it sound like a robbery gone bad. She was arrested and charged with first degree murder. At trial, in addition to testifying to the history of abuse, the defendant called two experts who testified that she was suffering from battered woman syndrome including major depression and posttraumatic stress disorder.
