An amendment may be made to any part of the Constitution of Ireland but only by referendum. An amendment must first be approved by both Houses of the Oireachtas (parliament), then submitted to a referendum, and finally signed into law by the President. Aside from constitutional referendums, the constitution also provides for a referendum on an ordinary bill, known as the ordinary referendum, but there has not been one so far.
I think such an act is worth a referendum.
