The report of the Commission of Investigation into the case of Dean Lyons has found that some Gardaí were sceptical about his credibility.
However, this view was never expressed to the DPP.
In 1997 Mr Lyons falsely confessed to the murder of two psychiatric patients at sheltered accommodation in Grangegorman and was charged with the murder of one.
However, the charges were later dropped after another man - Mark Nash - admitted to the murders.
Today's report takes the view that Garda written records of the case were incomplete and potentially misleading and concludes that Dean Lyons was asked inappropriate questions.
