An inquiry investigating alleged garda collusion in the murder of two RUC officers 19 years ago is reportedly taking legal action to get hold of a Cabinet document referring to the killings.
Reports this morning say the Smithwick Tribunal has informed the Government of plans to seek a High Court review of the refusal to release a report compiled by the then Minister for Justice, Gerard Collins.
The document was withheld on the grounds of cabinet confidentiality.
The tribunal is investigating claims that gardaí provided information to the IRA which led to the murders of RUC Chief Superintendent Harry Breen and superintendent Robert Buchanan in 1989.
The two men were ambushed while returning from a meeting with senior gardaí in Dundalk.
