Part 3: Planning Chapter 1: Planning Data Section 91: Interpretation of the Chapter Effect
This section provides definitions of key terms that are used throughout Chapter 1 of Part 3.
	Definitions of some of the terms cross refer to sections 84 and 87 as follows: planning data regulations (section 84(1)); planning data (section 84(2)); approved data standards (section 84 (3)); and planning data software (section 87(2)).
	This section also defines other terms including "process", "provided", "public authority", "relevant planning authority" and "relevant planning enactment".
	The definitions of "relevant planning authority" and "relevant planning enactment" set out the planning authorities which can be made subject to requirements under this chapter and the enactments which can give rise to a function for the purposes of the definition of planning data. The definition of relevant planning authorities provides a power for the Secretary of State to make regulations which specify additional relevant planning authorities, where those authorities either have functions relating to planning or development in England or relating to nationally significant infrastructure projects. The definition of relevant planning enactments provides a similar power to make regulations specifying further relevant planning enactments where they confer functions regarding planning or development in England or relating to nationally significant infrastructure projects.
