Back in October, the Pennsylvania General Assembly responded to the U.S. Supreme Court’s ruling in Miller v. Alabama, in which the nation’s high court ruled it was unconstitutional to have mandatory life without parole for juvenile offenders. With Act 204 of 2012, signed into law by Governor Tom Corbett on October 25, the legislature brought the state into compliance with the ruling.

The law is prospective, meaning it applies to convictions that occurred after June 24, the day before Miller came down.
