Britain's Privy Council has quashed the conviction of a man in New Zealand over the murders of his wife and daughter and ordered a new trial.
Mark Lundy, now in his 50s, has served 12 years of his minimum 20-year prison sentence, reports say.
Lundy, who maintains his innocence, was convicted in 2002 for the murders of his wife Christine and daughter Amber.
His lawyers lodged an appeal in Britain because New Zealand did not have a Supreme Court at the time.
Before New Zealand's Supreme Court was established in 2004, Britain's Privy Council heard cases from the the country's Court of Appeals.
Lundy's wife, 38, and daughter, seven, were murdered in their family home in August 2000.
Judges from Britain and New Zealand heard Lundy's appeal in June this year, with the decision for a new trial announced in London on Monday, reports say.
Lundy's lawyers had asked the court that fresh evidence be included in his retrial in New Zealand.
A New Zealand court was also to decide on whether he was to be released on bail while awaiting trial.
Lundy's lawyer told local media he was happy about the decision, as it would give them "the opportunity to have the evidence tested properly by a jury".
