The planning application process relies on people acting in good faith. There is an expectation that applicants and those representing them provide decision makers with true and accurate information upon which to base their decisions. However, under section 65(6) of the Town and Country Planning Act 1990, it is an offence to issue a false ownership certificate knowingly or recklessly.
If a local planning authority feels that an application does not accurately or fully describe the proposed development, or that it is in any way misleading, it is entitled to ask the applicant to amend it or rectify any omissions before it agrees to process the application.
Planning applications are publicised during the determination period so that any interested parties have the opportunity to comment. If any party considers that the application includes deliberately misleading information, or lacks important information that would be material to the decision, they should report this to the relevant local authority who will decide what, action is appropriate. Planning permission can be refused on the grounds that information provided was insufficient to accurately describe the nature and anticipated impacts of the proposed development.
