A date has been set for a judicial review into the way Justice Minister Judith Collins handled a compensation application by David Bain.
Mr Bain spent 13 years in prison for murdering his family in Dunedin in 1994, but was found not guilty at a retrial in 2009.
In a report released late last year, former Canadian Supreme Court judge Ian Binnie concluded Mr Bain was innocent and suggested he should receive compensation.
However, a review of that report, commissioned by Ms Collins, criticised those findings as legally flawed.
The judicial review is expected to be heard at the High Court in Auckland on 31 July.
