which the courts should respect it. However, it is not a legal
principle. Indeed, it is a departure from procedural norms relating
to pleading and disclosure. It requires justification similar to the
position in relation to public interest immunity (of which it is a form
of subset). It is not simply a matter of a governmental party to
litigation hoisting the NCND flag and the court automatically
saluting it. (para 20).

The

Government’s

claim

that

it

is

“only

possible

to

address

mischaracterisations in open to a limited extent” is therefore a matter of
choice rather than legal constraint (Observations, §1.2). Indeed, the ISC
Report noted that while the Government had placed “long-standing”
reliance on the NCND policy “in relation to any allegations about the
Agencies’ capabilities and operations”, it concluded that, “greater openness
regarding

the

Agencies’

activities

is

essential”.24

Accordingly,

it

recommended that “the Government will need to adopt a more open
approach to the Agencies’ activities in order to improve understanding and
public trust”.25 In particular, the ISC called on the Government “to avow
all of the Agencies’ intrusive capabilities”.26

The Council of Europe Commissioner for Human Rights (the “CoE HR
Commissioner”) likewise recently stated that, “NCND shields surveillance
decisions from effective scrutiny” and is “problematic” because “it prevents
a person from ever knowing if he/she has been the target of surveillance”.27
Extensive reliance on the NCND principle is unjustified in circumstances
where the UK Intelligence Services have used wide interpretations of
general powers to justify the operation of sweeping interception
programmes whose existence has until recently been concealed from
citizens and Parliament.
