Mark Lundy granted Supreme Court hearing

The convicted double murderer Mark Lundy has been granted a hearing in the Supreme Court, but only on very narrow grounds. Lundy was jailed in 2002 for murdering his wife Christine and daughter Amber in Palmerston North. This new hearing will be limited to questions around the Court of Appeal's use of what's known as 'the proviso' - a mechanism that allowed the Court of Appeal to dismiss Lundy's case, even though it found some of the scientific evidence at his retrial was inadmissible. University of Auckland law professor Mark Henaghan says that's the point Lundy's counsel is homing in on.
