Rejected petition HMG should decide & legislate on the confusion about which have priority (or similar), RACIAL groups or a RELGIOUS group?

Which have priority or the same - racial groups practising their customs (like wearing turbans, wearing burkas) or believers’ religious observances? Sikhs/Jews an ethnic race, cult or religion? In Mandla v Dowell Lee (1983) House of Lords found that Sikhs constituted a RACIAL group when a Sikh boy was refused a place at a school because he wore a turban. The appeal was therefore allowed under Race Relations Act. This judgement was based on Sikhs long shared history & collective consciousness distinguishing them from other groups in customs, geographical origin, language, being recognised as a separate group in the surrounding community. Jews regard a person a Jew if born of Jewish mother. A person can be a Jew even if not practising Judaism. Likewise can a person be converted to Sikhism by believing in karma & reincarnation unless BORN a Sikh? Belief in reincarnation does not require a believer to start wearing turbans, bangles, ceremonial swords, long beard, etc.
