This discretion shall not apply where it appears to the licensee that the child's presence in the bar could reasonably be regarded as injurious to the child's health, safety or welfare. For example, if someone has a child in a pub all day, while he or she is drinking there, even though it is lawful for him or her to be there, the licensee is entitled to decide that it is injurious to the child's interests for such people to remain on the premises. Under subsection (3), a licensee may permit a person aged 15 to 17 to be present in the bar, unaccompanied by a parent or guardian, but not after 8 p.m. Subsection (4) contains a number of exemptions to the general prohibition. The remaining subsections are broadly similar to existing provisions in section 34 of the 1988 Act.
