Let us say I, as a third party, make a formal complaint to my planning authority and, as an individual, go to South Dublin County Council, fill out the relevant form and make a complaint. As part of that I submit some documentation, including a copy of the section 10 declaration. The planning authority then investigates and decides to take action. I have initiated that process because I made the complaint. The planning authority would not be permitted to submit in court the section 10 declaration that I, as the original complainant, gave it a copy of.
