I have two questions. First, on page 297, section 159(2)(a), I refer to the word "abandoned". It states: "Without prejudice to subsection (1), where the planning authority or the Commission is of the opinion that an application, appeal or request made to it has been abandoned...". What does abandoned mean and who gets to decide? That is my first question. It is clear when something is withdrawn, and the other things there are clear, but I have never come across an abandoned application.
