Article 19 of the Planning and Development Regulations 2001– 2015, made under section 33(1)(b) of the Planning and Development Act 2000, specifies requirements in relation to displaying notice of an application for planning permission. Paragraph (3) provides that “Where a planning authority considers that the erection or fixing of a single site notice is not sufficient to comply with the requirements of sub-articles (1) and (2), or does not adequately inform the public, the authority may require the applicant to erect or fix such further site notice or notices in such a manner and in such terms as it may specify and to submit to the authority such evidence as it may specify in relation to compliance with any such requirements.” It is a matter for each planning authority to determine the circumstances in which it specifies additional requirements in relation to planning application notices under Article 19(3) and the Minister has no function in the matter.
