Lanai Unit Holdings Pty Ltd v Mallesons Stephen Jaques

In the Federal Circuit Court, Lanai Unit Holdings Pty Ltd sought to amend their statement of claim against Mallesons Stephen Jaques, a law firm engaged for a residential building development. The plaintiff alleged that the defendant's drafting of pre-sale contracts for the development did not comply with the Body Corporate and Community Management Act 1997 (Qld), leading to potential legal and financial repercussions for the plaintiff. The plaintiff originally sued for negligence and contravention of the Trade Practices Act 1974 (Cth), but the Trade Practices Act claims were struck out, prompting the plaintiff to seek leave to amend the statement of claim to add new negligence claims.

The central legal issue was whether the plaintiff's proposed amendments to the statement of claim, adding new causes of action for negligence that included a different counterfactual scenario and claimed a loss of a valuable commercial opportunity, were permissible under the law. Furthermore, there was a question of whether these new causes of action were time-barred. The court had to balance the plaintiff's right to amend pleadings against the defendant's right to be protected from stale claims and surprise.

The court allowed the plaintiff's application to amend the statement of claim, holding that the proposed amendments were not fundamentally altering the nature of the claim. The court reasoned that the new claims, although adding an inconsistent counterfactual scenario, were essentially an expansion of the existing negligence claims. The court further found that the new claims were not time-barred. Consequently, the plaintiff was granted leave to amend the statement of claim substantially in accordance with the proposed form, and the costs of the application were deemed costs in the proceeding.
