Frances Fitzgerald (Dublin Mid West, Fine Gael) | Oireachtas source

If the heads are published in July and if the pre-legislative scrutiny is completed, then drafting of the Bill can commence. Depending on the progress of the pre-legislative scrutiny and the issues that arise, the drafting will be done. I do not know whether it would be possible for it to be dealt with in the next session but it is important that the work starts. The heads will be published in July, pre-legislative scrutiny can then happen and if it moves ahead it can be introduced in the new term if that is possible.
