Please note that as and from June 1st 2012, Houses of the Oireachtas, as part of a review of its processes removed the requirement for documents laid to have a Parliamentary Number (PRN). As a consequence, the Government Publications Office ceased to issue PRN on behalf of the Houses of the Oireachtas Commission.
