In that case his Honour granted an injunction in favour of the proprietor and refused one in favour of the contractor even though the contract in that case had been "substantially" performed. His Honour noted that if that injunction were not refused, "the present stalemate may continue with the builder remaining on site persisting in its claim of right to continue with the suspension of the works which [he said] are estimated to take four to six weeks to complete". It may well be, he said, "that that period will have long since passed before the arbitration even commences". His Honour indicated that any decision of Lush J should be given "great weight".
27 The decision in Porter v Hannah Builders Pty Ltd, above, was also applied by Hunt J in Hughes Bros Pty Ltd v Telede Pty Ltd (1989) 7 BCL 204 where (at p. 206) his Honour notes that Mahon J in Mayfield Holdings Ltd v Moana Reef Ltd [1973] 1 NZ LR 309 disagreed with the decision of Megarry J in Hounslow London Borough Council v Twickenham Garden Developments Ltd [1971] Ch 233 where his Lordship had held there was an implied obligation on a proprietor not to revoke, in breach of contract, the licence of the contractor to remain on site. Mahon J (at pp 318-9) disagreed with Megarry J largely over the question whether the implication of such a term could be justified on the tests for implication, in particular, whether such a covenant was needed to give business efficacy to the contract, or whether the contract was effective without it, and whether such a term was so obvious that it "went without saying". Mahon J's concerns would seem to be justified in light of the criteria laid down by the Privy Council in BP Refinery (Westernport) Pty Ltd v Shire of Hastings [1910] ArgusLawRp 71; (1977) 16 ALR 363 at 376. Hunt J in Hughes Bros Pty Ltd v Telede Pty Ltd added this: "It is, his Honour said (and I agree) difficult to accept that either the builder or the proprietor would ever have agreed, [in the case before him] at the time of the formulation of the contract, to any express term carrying with it such extraordinary circumstances".
28 I was urged, however, by the Applicant to see the ruling in Porter v Hannah Builders Pty Ltd as, in effect, overtaken by events. I was referred also to the decision of Smith J in Robert Salzer Constructions Pty Ltd v Elmbee Pty Ltd, unreported SC Vic, 29 June 1990 (but see (1990) 10 Aust Cons L R 64). His Honour in that case indicated that as a matter of general principle the remedy of injunction, restraining the proprietor, should be available "in appropriate cases".
29 The difference between that case and this one, however, appears in this consideration. In that case Smith J noted that there was nothing on the evidence to suggest it was unreasonable to expect the parties to continue working together, which would be the effect of the injunction. However, in this case, on the materials I have, there are very direct allegations of a serious breakdown in relations between the persons involved - Mr Khor and Mr Hue. Given the alleged state of their relations, in contradistinction to the case before his Honour, I consider it would be unreasonable to expect the parties to continue working together. That is clearly suggested on the materials and I think his Honour's statement about "general principle" needs to be seen in light of the facts of the case before him which are different to those before me.
30 Factors suggesting events have overtaken the ruling in Porter v Hannah Builders Pty Ltd, above, include passage of the Domestic Building Contracts and Tribunal Act 1995 s53(1) enabling orders to be made which are "fair" to resolve a domestic building dispute and s97 of the Victorian Civil and Administrative Tribunal Act 1998 obliging this Tribunal in all proceedings to act "fairly" and according to the substantial merits of the case. It was said that these developments meant there was a serious question now as to whether Porter v Hannah Builders Pty Ltd should still be regarded as stating good law.
31 Obviously both such Acts (the former now being known as the Domestic Building Contracts Act 1995) have been passed since the decision in Porter v Hannah Builders Pty Ltd. In a sense they do advance the powers of this Tribunal in domestic building disputes. But neither Act, nor either provision in my view, can be regarded as statutorily reversing, sub silentio, Lush J's decision. Neither says anything about that decision either expressly or, in my view, implicitly.
