In Keshvanand Bharti case the Supreme Court of India enunciated the doctrine of basis structure. The case originated in February 1970 when Swami HH Sri Kesavananda Bharati, Senior Pontiff and head of "Edneer Mutt" - a Hindu Mutt situated in Edneer, a village in Kasaragod District of Kerala, challenged the Kerala government s attempts, under two state land reform acts, to impose restrictions on the management of its property. Although the state invoked its authority under Article 31, a noted Indian jurist, Nanabhoy Palkhivala, convinced the Swami into fighting his petition under Article 26 (not Article 29), concerning the right to manage religiously owned property without government interference. Even though the hearings consumed five months, the outcome would profoundly affect India's democratic processes.
