Pressure groups are forms of organisations, which exert pressure on the political or administrative system of a country to extract benefits out of it and to advance their own interests. The term ‘pressure group’ refers to any interest group whose members because of their shared common attributes make claims on the other groups and on the political process. Caste based pressure groups arise from a particular caste and influence government policies in favour of their social and political demands.
There is no explicit provision in the Constitution regarding PG (Pressure Group), yet they exist because of Article 19, which gives citizens the right to form associations and unions.
