Testimony from a notorious jail house snitch should never have been put to the jury in David Tamihere's first double murder trial, the Court of Appeal has been told.
Tamihere was convicted in 1990 for the murders of Swedish tourists Urban Hoglin and Heidi Paakkonen, who were killed the year before.
In 2017, Roberto Conchie Harris was found to have lied when he claimed Tamihere had confessed to murdering the pair. Tamihere was granted a rare Royal Prerogative of Mercy in 2020, which triggered an appeal hearing today in Wellington.
