Arnaout v Arnaout

The case of Arnaout v Arnaout was before the court to determine the availability of preliminary discovery in circumstances where insufficient information existed to identify the cause of action against a prospective defendant. The applicant sought discovery of documents from the prospective defendant to ascertain whether to commence proceedings and, if so, to determine the quantum of relief claimed. The applicant also sought to establish whether the prospective defendant held documents inconsistent with their representations.

The central legal issue before the court was whether preliminary discovery could be granted when there was insufficient information to identify the cause of action against the prospective defendant. The court had to balance the need for the applicant to obtain necessary information against the prospective defendant's right to protect their confidential information. The court considered whether the applicant had demonstrated a serious question to be tried and whether the documents sought were relevant to that question.

The court held that preliminary discovery could be granted, but on certain conditions. It found that while there was insufficient information to identify the cause of action, the applicant had demonstrated a serious question to be tried. The court reasoned that the documents sought were relevant to determining whether proceedings should be commenced against the prospective defendant and, if so, the quantum of relief claimed. The court imposed conditions to protect the prospective defendant's confidentiality, including limiting the scope of discovery and requiring the applicant to provide regular updates on their progress in identifying the cause of action.

The court ordered that preliminary discovery be granted on the conditions specified, allowing the applicant to obtain the necessary documents to determine whether to proceed with the prospective defendant and, if so, the appropriate quantum of relief.
