When you read sections 156O to 156R, you need to know what some words mean. An enforceable matter is something that has been decided, like a determination made under section 27, or a standard terms determination made under section 30M. It can also be a designated multinetwork service determination made under section 39, or an undertaking under Part 2A or Part 4AA.

You also need to know what a party is. A party is someone involved in an enforceable matter, and this can include a provider of a telecommunications service that is affected by a breach of an undertaking under Part 2A or Part 4AA. This means that if someone breaks the rules of an undertaking, the people who provide telecommunications services and are affected by this can be considered a party.

An enforceable matter can be other things too, like an approved code under Schedule 2, or a registered undertaking under Schedule 3A. All these things are considered enforceable matters in sections 156O to 156R.
