My Lords, the amendment seeks to put right a government oversight: there is no definition of national security under general definitions throughout the Bill. A principal statutory ground for authorising surveillance is,
“in the interests of national security”.
Another is “economic well-being” as far as it relates to national security. Left undefined, national security is unnecessarily open, broad and vague and, I suggest, likely to be abused. As the decision will continue to lie with the Secretary of State, the test will be met by whatever she or he subjectively decides is in the interests of national security or the economic well-being of the UK, so that individuals cannot foresee when surveillance powers might be used, granting the Secretary of State a discretion so broad as to be arbitrary. In the past, domestic courts have responded with considerable deference to government claims of national security—and not just domestic courts but other political parties at times. They have viewed them not as a matter of law but as Executive-led policy judgments. National security as a legal test is absolutely meaningless if left without a statutory definition.
The Joint Committee on the draft Bill recommended that the Bill should include definitions of national security and economic well-being. It is confusing even to use the measure of economic well-being, which should be subsumed, as recommended by the ISC, which found it “unnecessarily confusing and complicated”, saying that the agencies and Home Office had not “provided any sensible explanation” for including the term. I look forward to the Minister supplying that sensible explanation. Therefore, the core purposes for which extraordinary powers may be used remain undefined and dangerously flexible. The undefined tests of national
security and economic well-being risk interference with political and other lawful activity that ought to be unimpeded in a democratic society. In an era when parliamentarians from both Houses have been subjected to inappropriate surveillance by security services and the police, the continued undefined use of these terms in enabling legislation is not appropriate or sustainable. I beg to move.
