The UN's mandate to send Irish troops abroad would not be needed under the new system.
Ministers are set to approve plans to abolish the Triple Lock this morning.
The Programme for Government committed to reforming the current system, which requires a UN mandate, Government approval and a Dáil vote before Irish troops are deployed abroad.
Defence Minister Helen McEntee wants to remove the UN element - which gives Security Council members like Russia and the US the chance to veto deployments - and create a Double Lock instead.
Laois TD Brian Stanley is a member of the Oireachtas Defence and National Security committee and says a decision should be done by a vote of the Irish people:
