What is the meaning of "guardian" under the Care of Children Act 2004, in the context of the Sale of Liquor Act 1989?

Sale of Liquor Act sections which refer to a guardian are sections 157, 160 and 163.

The Ministry of Justice advises that the only people who are guardians (as defined by both these acts) are:

  • parents (except fathers who are not in a relationship with the mother and not on the birth certificate - unless appointed by the Court)

  • testamentary guardians (guardians appointed under a will).
