A local authority to whom the function of determining any such application as is referred to in subsection (1) above is delegated under section 3 of the principal Act may delegate either—
the function of determining all or any, or a specified class, of those applications.
A delegation made by a local authority under this section to an officer of theirs or of another local authority—
Where a local authority have under this section delegated to an officer of theirs or of another local authority the function of determining applications, and the officer so requests in the case of any application specified by him, the delegating authority shall themselves, instead of him, determine the application.
Where any functions have under this section been delegated to an officer of a local authority, any determination by him of such an application as is referred to in subsection (1) of this section shall, if it is notified in writing to the applicant, be treated for all purposes as a determination of the delegating authority.
Where an action has been brought against an officer of a local authority in respect of an act done by him in the discharge or purported discharge of functions delegated to him under this section and the circumstances are such that he is not legally entitled to require the delegating authority to indemnify him, that authority may nevertheless indemnify him against the whole or part of any damages and costs which he may have been ordered to pay or may have incurred, if they are satisfied that he honestly believed that the act complained of was done in the discharge of those functions and that his duty required or entitled him to do it.
In relation to any functions delegated under this section by a local authority to an officer of theirs or of another local authority, any reference to the local planning authority in any enactment relating to those functions shall (subject to the terms of the delegation and so far as the context does not otherwise require) be construed as including a reference to that officer.
