“2 Acquisition by descent (1) A person born outside the United Kingdom … after commencement shall be a British citizen if at the time of the birth his father or mother— (a) is a British citizen otherwise than by descent…”
“ You are claiming British Nationality by descent from the late Moghul Khan as your claimed father. Before I am able to authorise the issue of passport facilities, I must be satisfied that you are related to the late Moghul Khan as claimed. When applying for a British passport the onus is on the applicant to prove that he/she is a British citizen. The documents you have provided unfortunately do not conclusively prove this and you were requested to attend for an interview… during the interview you and your mother Shah Jehan Begum did not know much about Moghul Khan's life in the UK in general. You have failed to produce original passports of the late Moghul Khan to prove that he was present in Pakistan on or around 15 February, 1998 when you have been conceived, given your date of birth. You have also failed to produce progressive family photos to show a genuine family union. There was no single photo of you or your claimed father. Due to lack of family knowledge and the aforementioned documents (sic) bring in to doubt the veracity of the application. I am afraid I cannot be satisfied you are related to the late Moghul Khan as claimed… As your claimed father has passed away we are unable to offer DNA testing to prove the claim. ”
“The documents provided unfortunately do not conclusively prove [that you are a British National] and you have failed to provide any new additional contemporaneous evidence to prove otherwise. Unfortunately the option of DNA is not possible because your claimed father is deceased. ”
“ When submitting a passport application the onus is on the applicant to provide as much information as possible to support their application. When assessing the application passport officials must be provided with evidence of the applicant's identity and eligibility, and without this they can only assess the application on the documents that are provided. Unfortunately there were insufficient documents provided to establish that [the Claimant] was a holder of the identity she submitted. As [the Claimant] is claiming British Citizenship through her father, DNA testing with her mother does not provide any further evidence. ”
“1. We are frequently called upon to give advice on whether an individual may have automatically acquired British citizenship or one of the other forms of British nationality. Nationality is a matter of law on which only the courts can rule conclusively; however our advice is usually accepted by the passport and immigration authorities… 4.1The Immigration Act 1971 puts the burden of proving a status on the applicant or claimant… 4.3 As to the standard of proof required, it was held by the Immigration Appeal Tribunal in Kessori Khatun (4272) that "the standard of proof applicable to the right of abode, whether that be dependant on citizenship or relationship, is that of the normal balance of probabilities". In other words, a right of abode is established, or a claim to citizenship made out, if the evidence that it exists outweighs, however slightly, the evidence that it does not. Any requirement that the applicants/claimants produce "conclusive" evidence of their status, or establish their position "beyond doubt", sets the standard too high and risks censure by the courts if the case goes to judicial review. In official correspondence, such words and phrases are therefore best avoided. 4.4 Although in Kessori Khatun the Tribunal was concerned with the right of abode, the same standard is thought to apply to proof of citizenship for other purposes (eg for passport/consular protection purposes, voting, etc). ”
