Dedula v State of New South Wales

The plaintiff, Dedula, brought an action against the State of New South Wales, seeking damages for personal injury and loss arising from an incident that occurred while Dedula was in police custody. The dispute was heard in the Supreme Court of New South Wales. The plaintiff argued that the state's officers were negligent in their handling of Dedula, leading to the injuries and subsequent loss. The defendant, the state, denied liability and sought to amend its defence and strike out parts of the plaintiff's statement of claim.

The court had to determine whether the defendant was permitted to amend its defence to include a new defence of contributory negligence and whether certain parts of the plaintiff's statement of claim should be struck out due to alleged inconsistencies with earlier criminal proceedings and an earlier apprehended violence order. The court also needed to consider whether the doctrine of issue estoppel applied, preventing the defendant from raising certain defences or counterclaims that were or could have been raised in the earlier criminal proceedings.

The court found that the application to amend the defence was not in the interests of justice, as the proposed amendment was an attempt to introduce a new defence that was not previously disclosed and would cause significant prejudice to the plaintiff. The court also found that the proposed amendments were an attempt to relitigate issues that had already been decided in the earlier criminal proceedings, which were subject to issue estoppel. The court further found that the plaintiff's statement of claim was not inconsistent with the earlier criminal proceedings and that the doctrine of issue estoppel did not apply. The court dismissed the defendant's notice of motion to strike out parts of the statement of claim.

The court dismissed the defendant's application to amend the defence and struck out the notice of motion filed on 10 May 2017. The court found that the application to amend was an abuse of process and that the proposed amendments were an attempt to introduce new evidence and arguments that were not previously disclosed. The court found that the plaintiff had not acted unreasonably in not disclosing the proposed amendments and that the defendant's application to amend was an attempt to delay the proceedings and cause prejudice to the plaintiff.
