Documents released by Snowden links NSA to spying on US law firm
The National Security Agency was involved in the surveillance of an American law firm while it represented a foreign government in trade disputes with the United States, according to a new report based on a top-secret document that had been obtained by former NSA systems analyst Edward Snowden.
The February 2013 document shows that the Indonesian government had retained the law firm for help in trade talks, The New York Times reported in a story posted on its website on Saturday. The law firm was not identified in the document, but the Chicago-based firm Mayer Brown was advising the Indonesian government on trade issues at the time, the newspaper said.
The document itself is a monthly bulletin from an NSA liaison office in Canberra, the capital of Australia. The NSA's Australian counterpart, the Australian Signals Directorate, had notified the NSA that it was conducting surveillance of the talks, including communications between Indonesian officials and the American law firm, and offered to share the information, The New York Times reported.
Liaison officials asked the NSA general counsel's office, on behalf of the Australians, for guidance about the spying. The bulletin notes only that the counsel's office "provided clear guidance" and that the Australian eavesdropping agency "has been able to continue to cover the talks, providing highly useful intelligence for interested US customers," according to the Times.
The NSA and the Australian government declined to answer questions about the surveillance, the newspaper reported. The NSA said it "does not ask its foreign partners to undertake any intelligence activity that the US government would be legally prohibited from undertaking itself".
Officials have said Snowden took 1.7 million documents with him when he fled the US last year and has shared some of them with journalists. After a stint in Hong Kong, he has been granted temporary asylum in Russia and has been charged with theft and espionage in the United States.
Duane Layton, a Mayer Brown lawyer involved in the trade talks, told the Times that he did not have any evidence that he or his firm had been under scrutiny by Australian or US intelligence agencies.
"I always wonder if someone is listening, because you would have to be an idiot not to wonder in this day and age," he said in an interview with the newspaper. "But I've never really thought I was being spied on."
The NSA was prohibited from targeting Americans, including businesses, law firms and other organisations based in the US, for surveillance without warrants, the Times reported. Intelligence officials have repeatedly said the NSA does not use the spy services of its partners in an alliance of intelligence operations - Australia, Britain, Canada and New Zealand - to skirt the law.
The Times reported that the NSA can intercept the communications of Americans if they were in contact with a foreign intelligence target abroad, such as Indonesian officials.
The US agency was then required to follow so-called minimisation rules to protect their privacy, such as deleting the identity of Americans.
Most attorney-client conversations do not get special protections under American law from NSA eavesdropping, according to the newspaper.
