KHAPs are informal local councils in north-western India. They meet to lay down the law on questions of marriage and caste, and are among India’s most unflinchingly conservative institutions. They have banned marriage between people of different castes, restricted it between people from the same village and stand accused of ordering honour killings to enforce their rulings, which have no legal force. India’s Supreme Court once called for khaps to be “ruthlessly stamped out”. In April 2014, however, the Satrol khap, the largest in Haryana, one of India’s richest states, relaxed its ban on inter-caste marriage and made it easier for villagers to marry among their neighbours. “This will bring revolutionary change to Haryana,” said Inder Singh, president of the khap.
