Microsoft and close to 50 tech companies and civil liberties associations have renewed calls to reform the US Patriot Act ahead of the expiry of the law’s provisions governing bulk data collection

Microsoft, along with nearly fifty other technology civil rights associations and technology firms have signed an open letter to senior members of the US government calling for reform of the Patriot Act, a cause célèbre for Microsoft among other cloud firms in recent years.

Microsoft has previously criticised the US government’s bulk data collection practices, and the ability of its authorities to act on warrants beyond US soil (particularly when such acts contradict local laws where those businesses operate).

In an open letter to very senior members of the US government including Michael Rogers, director of the NSA, senate minority leader Harry Reid, and US president Barack Obama, the organisations reaffirm the need to end the US government’s bulk data collection practices, and make government and corporate reporting on any Foreign Intelligence Surveillance Court decisions more transparent.

The US Patriot Act Section 215, which currently serves as the legal basis for the NSA’s bulk collection of metadata, is due to expire in June this year.

“We the undersigned represent a wide range of privacy and human rights advocates, technology companies, and trade associations that hold an equally wide range of positions on the issue of surveillance reform. Many of us have differing views on exactly what reforms must be included in any bill reauthorizing USA Patriot Act Section 215,” the letter reads.

“That said, our broad, diverse, and bipartisan coalition believes that the status quo is untenable and that it is urgent that Congress move forward with reform.”

“It has been nearly two years since the first news stories revealed the scope of the United States’ surveillance and bulk collection activities. Now is the time to take on meaningful legislative reforms to the nation’s surveillance programs that maintain national security while preserving privacy, transparency, and accountability.”

Microsoft is among a range of technology companies in support of reforming how American legal entities treat data, both within the context of surveillance activities or general legal proceedings. But US lawmakers have signaled they are prepared to act on longstanding promises to reform the legal landscape. Last month American lawmakers introduced two bipartisan bills that seek to limit the reach of US courts over data stored in cloud services located outside the US, a move welcomed by a broad coalition of technology and telecoms firm – including Microsoft.
