R v TB (No 4)

In the case of R v TB (No 4), the primary focus was on the application for a certificate under section 39A of the Mutual Assistance in Criminal Matters Act 1987 (Cth) for specific documents and evidence related to the FBI operation known as Trojan Shield and the AFP investigation known as Operation Ironside. These operations were conducted to infiltrate an encrypted communication application, ANOM. The application sought material related to the establishment of the ANOM platform, the engagement between the FBI and AFP, and the functionality of the ANOM platform. The defendants argued that this material was crucial for their defence, particularly in relation to the validity of the controlled operation authorities obtained by the AFP.

The court had to determine whether it was in the interests of justice to grant the certificate, considering the mandatory factors in section 39A(3) of the Act. These factors included the likelihood of the USA granting the request, the admissibility and probative value of the evidence, and the balance of public interest considerations. The defendants contended that the AFP had previously acceded to requests under the Act, and given the uniqueness of Operation Ironside, they should be permitted to explore any potential illegality. However, the court found that the defendants had not provided detailed or persuasive submissions regarding the relevance and admissibility of the sought material or the evidence of Federal Agent Cheviron.

The court concluded that while it was a possibility that some of the requested material could be relevant, the generality of the request and the lack of specificity in the submissions made it difficult to assess the admissibility and probative value of the evidence. Additionally, there was evidence that the USA would not execute any mutual assistance request if made. Given these considerations, the court was not satisfied that it was in the interests of justice for the Attorney-General to make the request. Consequently, the application for the certificate was refused.
