Before giving a direction under the last preceding section, the Minister shall give notice in writing of his proposed direction to the local planning authority to whose decision that direction relates and to any person who made, and has not since withdrawn, a claim in respect of that decision, and, if so required by that authority or by any such person, shall afford to each of them an opportunity to appear before, and be heard by, a person appointed by the Minister for the purpose.

Where the Minister gives a direction under the last preceding section, the Minister shall give notice of the direction to the authority to whose decision the direction relates and to every other person (if any) who made, and has not since withdrawn, a claim in respect of that decision ; and where a notice under this subsection is given to a person who made such a claim, that person, if he does not withdraw the claim, may at any time within thirty days after the service on him of the Minister's notice under this subsection give notice to the Minister modifying the claim.

Subject to any modification by virtue of a notice given by a claimant under the last preceding subsection, where the Minister gives a direction under the last preceding section in respect of a decision of a local planning authority, any claim made in respect of that decision shall have effect as if it had been made in respect of the decision which by virtue of the direction is substituted for the decision of the authority, or, as the case may be, as if it had been made in respect of the decision of the authority as modified by the direction.
