Ryan Stage v The Government of The Commonwealth of Australia

The extradition court has a residual jurisdiction to prevent abuse of the extradition process itself. The jurisdiction is concerned with manipulation, bad faith, collateral purpose or comparable misuse of the extradition regime by the requesting authority. It is distinct from abuse of process under the law of the requesting state.

A possible domestic abuse argument, or uncertainty about the requesting state’s criminal law and sentencing procedure, does not by itself establish extradition abuse. Those issues are ordinarily for the requesting state’s courts. Extradition should be refused only where there are reasonable grounds to suspect that the extradition process has itself been abused and the requesting authority cannot dispel that suspicion.

Australia requested the extradition of a British citizen to face charges concerning the importation and possession of cocaine and dealing with suspected proceeds of crime. The charges differed from those accepted during plea negotiations in Australia. The appellant argued that the change exposed him to a higher sentence and constituted an abuse of process.

The District Judge dismissed the appeal, holding that any domestic abuse argument should be determined by the Australian courts and that the evidence did not establish abuse of the extradition process. Julian Knowles J granted leave to appeal. The central issue was whether the requesting authority’s change in prosecutorial position gave rise to an arguable abuse of the United Kingdom extradition process.

1. Appeal dismissed. The appellant had not shown any arguable abuse of the extradition process.
2. The court affirmed the residual abuse jurisdiction identified in R (Bermingham and others) v Director of the Serious Fraud Office and R (Government of the United States of America) v Bow Street Magistrates’ Court (the Tollman case). The extradition court must identify the alleged conduct, decide whether it could amount to abuse, consider whether there are reasonable grounds to believe it occurred, and refuse extradition unless satisfied that it did not occur.
3. The jurisdiction concerns abuse by the prosecuting or requesting authority of the extradition process. It does not ordinarily permit the extradition court to decide questions of local criminal law, evidence, sentencing or domestic abuse of process. Those matters are for the Australian court. The distinction between domestic abuse and extradition abuse must be maintained.
4. The change from the negotiated charge to the extradition charges did not provide reasonable grounds to suspect manipulation, bad faith, collateral purpose, suppression of facts or usurpation of the extradition regime. The respondent had explained its position fully and was not obviously wrong in seeking to rely on section 311.4 of the Criminal Code to aggregate quantities.
5. The doctrine of specialty, under section 42 of the Extradition Act 1988, also operated against the respondent. If the appellant succeeded in an abuse application in Australia, Australia could not proceed on the principal extradition charge, although similar or lesser charges based on the same facts might remain available.

• District Judge (Magistrates’ Court): On 4 October 2022, dismissed the appellant’s challenge to extradition, finding no abuse of the extradition process.
• High Court (King’s Bench Division): Leave having been granted by Julian Knowles J, the court dismissed the appeal.
