United Kingdom Supreme Court, [2013] UKSC 62, 9 October 2013 (Al-Jedda)

Revocation of British citizenship on national security grounds. Involvement in the activity of terrorist groups. Risk of statelessness. 

British Nationality Act 1981 (UK)

The revocation of British citizenship of a naturalized person who lost his/her first citizenship (in the case at issue, the Iraqi nationality) violates the prohibition of statelessness. In fact, the probability that this person will reacquire his/her previous citizenship in a quick and simple way is not enough to prevent the risk of statelessness.
