Finally, under the Immigration Act 1971, the concept of patriality or right of abode was created. CUKCs and other Commonwealth citizens had the right of abode in the UK only if they, their husband (if female), their parents or their grandparents were connected with the United Kingdom. This placed the UK in the rare position of denying some of its nationals entry into their country of nationality. However, the concept of patriality was only a temporary solution to halt a sudden wave of migration. The British government later reformed the law, resulting in the British Nationality Act 1981.
