in spite of the fact that the 1981 act repealed most of the provisions of the 1948 act and the nationality clauses in subsequent independence acts, the acquisition of new categories of british nationality created by the 1981 act was often dependent on nationality status prior to 1 january 1983 (the date the 1981 act entered into force), so many of the provisions of the 1948 act and subsequent independence acts are still relevant. not taking this into account might lead to the erroneous conclusion, for example, that the 1981 act's repeal of the nationality clauses in the kenya independence act of 1963 restored british nationality to those who lost their cukc status as a result of kenya's independence in 1963. this is one of the reasons for the complexity of british nationality law; in complicated cases, determining british nationality status requires an examination of several nationality acts in their original form.
