The appellant, a Canadian citizen, was extradited from Brazil to Canada to face fraud charges under an arrangement that prohibited his prosecution for other offences committed prior to the extradition request.
After serving his sentence for the initial charges, the appellant remained in Canada and was subsequently charged with additional offences committed before his extradition.
He argued that the extradition arrangement provided perpetual immunity from prosecution for those prior offences.
The Supreme Court of Canada dismissed the appeal, holding that the immunity under the Rule of Specialty and the extradition arrangement only lasts until the fugitive has had a reasonable opportunity to return to the requested state.
