I do not agree with the principle of it: it should be done on notice.
Clause 9 means that individuals will not be able to challenge deprivation of their nationality as they will not be aware or told that they are no longer British citizens, and the time limit for appeal may run out before the individual becomes aware that their rights have been stripped. As Reprieve has pointed out, under these proposals, a person accused of speeding would be afforded more rights than someone at risk of being deprived of their British nationality.
