Power to regulate foreign contributions enables prohibition or prior permission where national interest or communal harmony is threatened. Central Government may prohibit acceptance of foreign contribution or require prior permission and prescribed intimations regarding foreign contribution and foreign hospitality for persons or classes not otherwise authorised. The Government can impose prohibitions, prior permission requirements and reporting obligations, but only if satisfied that acceptance is likely to prejudice sovereignty and integrity, public interest, freedom or fairness of elections, friendly relations with foreign States, or harmony among religious, racial, social, linguistic or regional groups, castes or communities.
