Tavitian v Commissioner of Highways

In the Supreme Court of South Australia, Mr. Tavitian brought a case against the Commissioner of Highways, contesting the compulsory acquisition of his land and the associated compensation. The dispute arose due to the alleged damage to Mr. Tavitian’s property caused by the runoff from the duplicated carriageway of the Sturt Highway. Mr. Tavitian sought declarations, injunctions, and damages based on the Land Acquisition Act (LAA) and common law nuisance. The Commissioner applied for summary judgment, arguing that Mr. Tavitian’s claims were unsustainable as a matter of law.

The primary legal issues before the court were whether Mr. Tavitian's claims were legally tenable and if there were any justiciable questions that could be answered in his favour. Specifically, the court had to determine whether the LAA applied to the Commissioner’s actions and if Mr. Tavitian could claim compensation under the LAA or common law nuisance. The Commissioner contended that Mr. Tavitian's delay in initiating proceedings prejudiced his defence and that statutory immunity protected the Commissioner from liability.

The court found that Mr. Tavitian's claims for declarations concerning the LAA and Highways Act were unsustainable as the LAA did not apply to the Commissioner's actions regarding the duplication works. The court also ruled that Mr. Tavitian's claims for remediation and reparation, based on the LAA, were not tenable. However, the court noted that Mr. Tavitian might have a viable claim in nuisance, although this claim faced the hurdle of statutory immunity. The court decided not to grant summary judgment on the nuisance claim because it had not been expressly pleaded and thus was not conclusively shown to be without merit. Instead, the court suggested that if Mr. Tavitian wished to pursue a nuisance claim, he should do so through fresh pleadings.

The final orders of the court were that summary judgment should be granted to the Commissioner on Mr. Tavitian’s application for declarations concerning the LAA and the Highways Act, as well as for remediation and reparation. However, the court did not grant summary judgment on the potential nuisance claim, encouraging Mr. Tavitian to proceed with fresh pleadings if he wished to pursue this claim.
