There are also other considerations. There could be several options open to a Government in the matter. The Oireachtas could decide that it will not change the impugned law. The ultimate nightmare could arise where an incompatibility was established with constitutional provision in Strasbourg. That does not arise under this legislation. However, such a scenario would oblige the Government to institute the referendum procedure. A wide variety of circumstances could give rise to declarations of incompatibility. The making of the declaration is formally before both Houses. This is a sufficient safeguard to ensure that the Government pursues whatever solution to the problem is necessary.
