Spies Without Borders: International Law and Intelligence Collection
To the surprise of many, it turns out that Canada’s chief security intelligence agency – the Canadian Security Intelligence Service (CSIS) –may not legally collect covert intelligence abroad. That is at least one interpretation of a Canadian Federal Court decision issued in October 2007, but only released publicly in 2008. At issue was whether the court had the jurisdiction to issue a warrant under the Canadian Security Intelligence Service Act (CSIS Act) in investigations concerning Canadians taking place overseas. CSIS had sought the warrant because the targets of the investigations, as Canadians, potentially enjoyed privacy rights under Canada’s constitutional bill of rights, the Canadian Charter of Rights and Freedoms.
Faced with this conundrum, there were two plausible courses of action open to the court. First, it could have concluded that the CSIS Act’s warrant provisions extended only as far as authorizing searches and seizures in Canada. While this approach would have left open the question whether constitutional rules applied to CSIS’s extraterritorial conduct, it would have allowed the court to avoid the incongruity of a Canadian court “legally” authorizing an invasion of privacy taking place in a foreign jurisdiction whose own laws would probably be violated by the action.
Second, the court could have reached even further and concluded that CSIS itself has no statutory authorization to conduct extraterritorial investigations, pursuant to its core, statutory mission to collect intelligence relating to threats to the security of Canada. This approach would avoid the constitutional question entirely, but with the consequence of greatly limiting the scope of CSIS’s basic jurisdictional competence.
