NEW DELHI: India’s top television yoga expert has challenged a landmark court ruling legalising gay sex, claiming it is a “disease” that can be cured by yoga, reports said on Thursday. Swami Baba Ramdev filed the petition on the grounds that the Delhi High Court “erred” in decriminalising “unnatural sex acts” last week and that homosexuality was an illness which could be treated. “It can be treated like any other congenital defect. Such tendencies can be treated by yoga, pranayama (breathing exercises) and other meditation techniques,” he said in the challenge filed in the Supreme Court. Last week’s judgment reversing a colonial-era ban on homosexuality has met with widespread opposition among many religious groups and conservatives who say same-sex relationships threaten the fabric of traditional Indian society. Swami Ramdev said homosexuality caused “mental bankruptcy” and was “against God and creation.” Under the Indian legal system, any person can challenge a court decision in a higher court. An astrologer, Suresh Kumar Kaushal, has also filed a petition against the high court decision today, arguing that if gay sex is legalised, “tomorrow people might seek permission for having sex with animals”.
