United Kingdom Supreme Court, [2015] UKSC 2019, 20 March 2015 (Pham)

Revocation of British citizenship on national security grounds. Involvement in terrorist activities. Risk of statelessness. 

British Nationality Act 1981 (UK)

Even when a naturalized person is stripped of his/her British citizenship on national security grounds, statelessness must be avoided. If the naturalized person lost his/her primary citizenship due to or, anyway, after naturalization, the deprivation decision would result in statelessness.
