Section 15 introduces an entirely new provision in the form of the new section 34A to be inserted in the 1988 Act. It requires that persons under 21, apart from those in the company of a parent or guardian, will carry an age document in order to enter and remain in the bar, as opposed to any other room, of licensed premises. An age document may be a Garda age card, a passport, an identity card of a member state of the European Union, a driver's licence or a document prescribed in regulations to be made by the Minister. An age document is not required in order to gain access to any other parts of the premises.
