Statutory basis. Section 34(1) of the Planning and Development Act 2000 (as amended) requires a planning authority to consider any submission or observation made to it in accordance with the Regulations. Article 29 of the Planning and Development Regulations 2001 (as amended) sets the window: a submission or observation must be received by the authority within five weeks beginning on the date of receipt of the application, and must be accompanied by the prescribed fee of €20. A submission received after the window, or without the fee, is invalid and the authority must return it.
