Lawyers for the last man to be sentenced to death in Northern Ireland are to seek access to a secret dossier in a bid to overturn his conviction.
West Belfast man Liam Holden was found guilty of murdering a soldier in the early 1970s, but his death sentence was commuted to life imprisonment.
Mr Holden said he was subjected to water torture to extract a confession.
Earlier this year the Criminal Cases Review Commission referred his conviction to the Court of Appeal.
The CCRC referred the case for appeal on the basis that the conviction may have been unsafe.
Mr Holden's lawyers have told judges there was a confidential annex in the case which they have not seen.
