Article 25.5 provides that from time to time, the Taoiseach may cause an up to date text of the Constitution to be prepared in Irish and in English, embodying all of the amendments made so far. Once this new text has been signed by the Taoiseach, the Chief Justice and the President, it is enrolled on vellum and deposited with the office of the Registrar of the Supreme Court. Once enrolled, the new text becomes conclusive evidence of the Constitution, and supersedes earlier enrolled copies. The Constitution has been enrolled six times: in 1938, 1942, 1980, 1990, 1999, and 2019.
