IPT Ruling on Interception

News article - 6 Feb 2015
The Investigatory Powers Tribunal (IPT) has today issued its second judgment on challenges to the UK’s interception powers and intelligence-sharing arrangements.
The judgment reaffirms the IPT’s main December ruling which found strongly in favour of the Government. The Court ruled that the legal frameworks governing both the bulk interception regime (found in section 8(4) of the Regulation of Investigatory Powers Act or RIPA) and the intelligence-sharing regime were fully compatible with human rights, in particular the right to privacy.
Today’s judgment focuses primarily on a discrete and purely historical issue – whether those legal frameworks were also fully compatible at a point before these legal proceedings began.

Who we are

GCHQ is an intelligence and security organisation, working to keep Britain safe and secure in the challenging environment of modern communications.


What we do

UK citizens today conduct much of their lives over the internet, as do the Government, the Armed Services, Law Enforcement and industry.

For the UK to be safe and successful, the cyber connections and infrastructure we use need to be safe and secure. GCHQ plays a major role in making that a reality using our expertise and experience.

Everything we do is governed by law, and overseen by the Foreign Secretary and other Ministers.

Support to Military Operations

Today, one of GCHQ's main tasks is to help protect the UK Military wherever they are deployed. This is not a new remit; it is in fact the whole reason GCHQ was formed in the first place.
The need to help protect the Military and arm them with the knowledge to keep them one step ahead proved to be the catalyst needed to develop Signals Intelligence at the start of World War One.
A lot has changed since 1914. The way the world communicates today is vastly different, but some things remain constant.

Our journey


GCHQ has been on a long and fascinating journey from the earliest days of the UK's Signals Intelligence effort at the beginning of World War I to the challenging technologies of today.
