The Sabarimala Sree Dharma Sastha Temple (; ) is a temple complex located at Sabarimala hill inside the Periyar Tiger Reserve in the Ranni-Perunad Village, Ranni Taluk,Pathanamthitta district, Kerala, India. It is one of the largest annual pilgrimage sites in the world, with an estimate of over 10 to 15 million devotees visiting every year.

But the lone woman judge, Indu Malhotra noted in her dissenting judgement that "what constitutes an essential religious practice is for the religious community to decide" and not a matter that should be decided by the courts. She added that "notions of rationality cannot be invoked in matters of religion by courts." The Chief Justice, Dipak Misra, stated that the selective ban on women was not an "essential part" of Hinduism but instead a form of "religious patriarchy." Justice Dhananjaya Y.
