R v Ellis

Frederick John Ellis and Ronald Angelo Favaloro were jointly charged with trafficking in dangerous drugs, specifically heroin and methylamphetamine, between April and November 1997. Ellis sought to exclude certain evidence obtained during a police undercover operation on the grounds that it was tainted by the illegal purchase and possession of drugs by a member of the Queensland Police Service (QPS). The legal issues centred on whether evidence obtained through illegal means should be excluded from the trial, balancing the need to convict wrongdoers against the risk of endorsing unlawful police conduct.

The court considered the principle from Bunning v Cross that the admissibility of illegally obtained evidence depends on balancing the public policy goals of convicting wrongdoers and preventing unlawful police conduct. The court noted that the evidence in question was obtained in a controlled operation, following guidelines established after the Trident Inquiry and in compliance with the recommendations of that report. The court found that the operation was conducted within a regime of strict supervision and that the evidence was reliable and cogent. The court emphasised the significant public interest in convicting those involved in drug trafficking, particularly when large quantities were involved. The court concluded that there was no compelling reason to exclude the evidence, and the application to exclude it was refused.

The court's reasoning was grounded in the need to balance the public interest in convicting serious offenders against the risk of endorsing unlawful police conduct. The court found that the evidence was obtained within a controlled regime and did not involve the kind of unrestrained illegality that had led to the exclusion of evidence in previous cases. The court held that the public interest in convicting drug traffickers outweighed the need to exclude the evidence, and the application was dismissed.
