Judgment
1 MEAGHER JA: I agree with Handley JA.
2 HANDLEY JA: This appeal is the latest round in the litigation generated by the construction of a four storey dwelling on 7 Gilliver Avenue, Vaucluse. On 14 November 1994 the respondent Council granted development consent for the erection of the building and construction began on 20 August 1995. On 5 July 1996 the appellants, who own 5 Gilliver Avenue, commenced proceedings in the Land and Environment Court against the owners of No 7 and the Council, attacking the validity of the development consent and seeking an order for the demolition of the building.
3 On 19 November Bannon J dismissed the proceedings. He held that the development consent was invalid, but because of the applicant's delay he refused to order the building to be demolished.
4 On 24 September 1997 the appellant commenced proceedings in the Federal Court against the owners of 7 Gilliver Avenue, their architects, the Council, and the builders. An amended statement of claim, filed on 21 November, pleaded many causes of action, but the only cause of action pleaded against the Council was in negligence, based on an alleged duty of care owed to the plaintiffs when the Council dealt with the development and building applications by the owners of 7 Gilliver Avenue. The applicants pleaded causes of action against the architects based on the Trade Practices Act and the Fair Trading Act.
5 On 3 March 1998 Wilcox J struck out the amended statement of claim but gave leave to the applicants to re-plead the causes of action against the architects and the Council. He considered that the claims against the architects made it appropriate to allow the applicants to join with those claims any negligence claim against the Council. However in the context his Honour should be understood as referring to claims based on a duty of care alleged to be owed by the Council in relation to its consideration of the development and building applications.
6 Pursuant to that leave, the then applicants filed a further amended statement of claim pleading a cause of action against the Council in relation to its consideration of the development and building application. The damage alleged against the Council, as particularised, was that the building constructed pursuant to the development consent overshadowed the applicants' property, interfered with its use and enjoyment, and reduced its value.
7 The trial proceeded before Wilcox J, who gave judgment on 23 March. He found that the applicants had sustained no damage from the breaches of duty they had alleged against the architects and the Council, and he dismissed the proceedings.
8 On 27 May the first appellant commenced further proceedings in the District Court against the builders, the owners of 7 Gilliver Avenue and the Council. The proceedings against the defendants, other than the Council, have been settled on undisclosed terms, but the action has proceeded against the Council. At some stage the second appellant was added as a plaintiff in the proceedings.
9 Paragraph 6 of the statement of claim pleaded that the development on 7 Gilliver Avenue was contrary to s 76(2)(a) of the Environmental Planning and Assessment Act (the Act), and illegal because the development consent was not valid. It also pleaded that the development was illegal under s 76(2)(b) because it was not carried out in accordance with the conditions of the development consent. Paragraph 7 alleged that the development constituted a nuisance which caused special damage to the plaintiff. The remaining particular of damage against the Council, which was particularised in para (a) under para 7, was as follows:
"Damage to the plaintiffs' house caused by vibrations caused during/by the said rock excavation".
10 Paragraph 10 alleged that the likelihood of damage being caused to the plaintiff was well known to the defendants before and during the development. Paragraph 11, which pleaded the cause of action alleged against the Council, stated that it was the authority "charged with the [responsibility] of ensuring compliance with the statutory provisions relating to development" in the municipality, and it "failed to carry out its duty [to] ensure compliance with those statutory provisions". The particulars of damage to this paragraph incorporated by reference the particulars to para 7.
11 The Council applied, by notice of motion dated 11 April 2001, for the action to be summarily dismissed pursuant to DCR Pt 11A r 3, or for the statement of claim to be struck out, pursuant to DCR Pt 9 r 17. The application was based on res judicata, issue estoppel, or an Anshun estoppel derived from the proceedings in the Federal Court. On 18 May Karpin DCJ gave judgment and ordered that the action be stayed. Later on 31 July she ordered that the action be dismissed pursuant to DCR Pt 11A r 3. She said:
"I am satisfied that all matters which are now sought to be litigated against the Council in this Court either were, or should have been before Wilcox J. If it be the case that the plaintiffs failed adequately to prosecute their case in negligence in those proceedings, they cannot now be permitted to split their action and relitigate the same factual material on the same issues, merely because one aspect of alleged negligence may have been overlooked. The parties are bound by the findings made by Wilcox J, and no issue remains to be litigated".
