R v Rogerson; R v McNamara (No 2)

The defendants, Rogerson and McNamara, appealed against the setting aside of subpoenas which required them to produce documents to the Australian Crime Commission. The subpoenas were sought by the prosecution as part of their preparation for the defendants' trial for drug trafficking offences. The defendants argued that the subpoenas were invalid because the prosecution was not instituted as a result of an operation or investigation carried out by the Commission in performance of its functions, and therefore, the documents were not necessary for the purposes of the prosecution.

The primary legal issue before the court was whether the subpoenas were appropriately issued and whether it was necessary or appropriate to cross-examine the deponent of the affidavit in support of the application to set aside. The court had to determine whether the prosecution met the statutory criteria for issuing the subpoenas under the relevant legislation. The court also had to consider the meaning of the term "necessary" in the context of the legislation and whether the prosecution had satisfied the requirements to establish necessity.

The court held that the subpoenas were not appropriately issued because the prosecution was not instituted as a result of an operation or investigation carried out by the Commission. The court found that the prosecution was not "necessary" for the purposes of the prosecution as defined by the legislation. The court further held that there was no requirement to cross-examine the deponent of the affidavit in support of the application to set aside. The court set aside the subpoenas on the basis that they did not meet the statutory criteria for issuance.

The court ordered that the subpoenas be set aside and that the defendants were not required to produce the documents sought by the subpoenas. The court's decision was based on a strict interpretation of the relevant legislation and the evidence presented to the court. The court's reasoning emphasised the importance of following the statutory criteria for issuing subpoenas and the need for the prosecution to establish necessity before requiring the production of documents.
