8 RAID also submitted that they should be joined as a party to the proceedings as a matter of public interest. RAID argued that as the matter had generated a significant amount of public interest in the local area, including approximately 90 objections, and DA X05/0412 sought to develop a significant parcel of land in Blackheath, the matter was one that was of significant public interest.
Council's submissions
9 The Council supported the joinder of RAID as a party to the proceedings. The Council supported the submission that there was significant public interest in all of the issues being ventilated in the merit proceedings.
Applicant's submissions
10 The Applicant submitted that RAID should not be joined as a party to the proceedings on the basis that the questions of law and issues of merit outlined by RAID could be ventilated and raised by the Council and resident objectors during the course of the merit proceedings, except for the second question of law relating to whether DA X05/0412 constituted designated development. The Applicant submitted that even if DA X05/0412 could be described as "sewerage systems or works" within the definition of Sch 3 of the EP&A Act, the development could not be classified as designated development pursuant to the EP&A Act because the nature, character and extent of the proposed on-site sewerage system was ancillary to the use of the land for tourist and residential accommodation. Accordingly, it was not appropriate to join RAID on the basis of the designated development issue, as that issue had no merit.
