170 Mantu UK citizenship and placed in legal limbo. His status in the UK is that of an alien placed by the UK executive in detention awaiting removal to a country that does not recognize him as one of its nationals and cannot be forced to take him back. 4 Conclusions The UK rules on citizenship deprivation have been increasingly relaxed in order to allow the government to fight against suspected terrorists by depriving them of their UK citizenship. Where national security and terrorism are at stake, statelessness has proven to be the only potentially effective ground for contesting the power of the UK executive to take away citizenship. British courts have confirmed that they are the ultimate adjudicator as to whether a person is made stateless as a result of a citizenship deprivation order but their engagements with what constitutes statelessness under the 1954 Convention have led to mixed results. This outcome relates to the dissatisfaction expressed by the appeal court in the Al-Jedda case when it had to uphold the prohibition of creating statelessness despite the fact that the citizenship deprivation order had been found conducive to be public good.26 This position points towards the problematic relation between statelessness, alleged involvement in terrorism and the difficulty of thinking in terms of every person’s right to a nationality rather than the overriding importance of state security. The misinterpretation of the definition of stateless person in the B2 case is equally worrisome for the correct implementation of the safeguards against statelessness contained in the 1954 and 1961 UN Conventions. 26 Al-Jedda v SSHD [2010] EWCA Civ 358, paras. 124-131. tilburg law review 19 (2014) 163-170
