Regulation 21 Provision of information

A charging authority may, for the purpose of considering whether any of Parts II to V of these Regulations applies to any person, by written notice request the person (and any person making an application for the purposes of Part IV on behalf of such a person) to furnish to the authority within such period, not being less than 21 days, as it may reasonably specify such information specified in the notice as it may reasonably request of that person to assist it in considering that question.
