If the President of Ireland is absent, becomes incapacitated, dies, resigns, is removed from office or fails to perform their functions, the Presidential Commission steps in to perform the functions of the President.
The Presidential Commission consists of the Chief Justice, the Ceann Comhairle (Chairperson) of the Dáil and the Cathaoirleach (Chairperson) of the Seanad. If any of those people are unable to act, the President of the High Court, the Leas (Deputy) Ceann Comhairle and the Leas (Deputy) Cathaoirleach, respectively, can act as members instead.
Any 2 of the members of the Presidential Commission can perform the functions of the President. The Presidential Commission frequently acts instead of the President while they are abroad, for example, by signing Bills into law.
