Jeremy Bamber is to renew his legal bid to challenge his convictions for murdering five relatives more than 25 years ago.
A High Court judge in London recently rejected his application for permission to seek judicial review of a refusal by the Criminal Cases Review Commission (CCRC) to refer his case back to the Court of Appeal.
The CCRC is an independent body which investigates the safety of convictions and any possible miscarriages of justice.
After studying the case papers in private, a single judge turned down his application.
But a spokeswoman for the Judicial Office confirmed yesterday that Bamber is to renew his application at a hearing in open court.
