(ii) While applying the affinity test, which focuses on the ethnological connections with the Scheduled Tribe, a cautious approach has to be adopted. A few decades ago, when the tribes were somewhat immune to the cultural development happening around them, the affinity test could serve as a determinative factor. However, with the migrations, modernisation and contact with other communities, these communities tend to develop and adopt new traits which may not essentially match with the traditional characteristics of the tribe. Hence, the affinity test may not be regarded as a litmus test for establishing the link of the applicant with a Scheduled Tribe. Nevertheless, the claim by an applicant that he is a part of a Scheduled Tribe and is entitled to the benefit extended to that Tribe, cannot per se be disregarded on the ground that his present traits do not match his tribe’s peculiar anthropological and ethnological traits, deity, rituals, customs, mode of marriage, death ceremonies, method of burial of dead bodies, etc. Thus, the affinity test may be used to corroborate the documentary evidence and should not be the sole criteria to reject a claim. Burden to prove lies upon applicant – In case material produced by applicant does not prove his claim, Committee cannot gather evidence on its own to prove or disprove his claim.”
