Areva NC (Australia) Pty Ltd v Summit Resources (Australia) Pty Ltd [No 3]

In the Supreme Court of Western Australia, Areva NC (Australia) Pty Ltd brought an action against Summit Resources (Australia) Pty Ltd. The nature of the dispute was focused on the discovery of documents, specifically whether Summit Resources was required to provide full documents or merely extracts thereof, given claims of irrelevance and legal professional privilege. The case centred on the interpretation and application of certain rules under the Supreme Court Rules 1971 (WA), including Orders 26 and 37, and whether these rules permitted the masking of parts of discovered documents.

The legal issues the court needed to resolve included whether the oath of discovery was conclusive regarding the relevance of extracts provided, and whether the entitlement to mask certain parts of documents existed. Additionally, the court had to determine the interpretation of the term 'document' and how rules O 1 r 4A and r 4B related to the masking of documents. The case hinged on the balance between the rights of the parties to obtain relevant information and the protection of legally privileged information.

The court held that the oath of discovery was not conclusive as to the relevance of the extracts provided, and that Summit Resources was not entitled to mask parts of the discovered documents. The term 'document' was interpreted to include any record of information, whether in physical or electronic form, and thus masking parts of a document would not comply with the discovery obligations. Furthermore, the court found that the relevant rules permitted the application of masking only in specific circumstances, which were not met in this case. The application for inspection of unredacted documents was allowed in part, reflecting the court's careful consideration of the rights and obligations of the parties under the rules of court.

The final orders of the court reflected its decision, allowing the inspection of certain unredacted documents while upholding the importance of protecting legally privileged information. The court's ruling clarified the scope of discovery obligations and the limitations on masking documents, providing guidance for future litigation involving similar issues.
