In a landmark judgement, the Supreme Court on Thursday struck down Section 377 of the Indian Penal Code (IPC) and decriminalised homosexuality.

From 1861 to 2018, here's a brief history of Section 377 in India: 
 

1861: Section 377 introduced in India by the British.

It was modelled on the Buggery Act of 1533. ‘Buggery’ was defined as an unnatural sexual act against the will of God and man, criminalising anal penetration, bestiality and homosexuality.

A bench of then Chief Justice AP Shah and Justice S Murlidhar ruled, “We declare section 377 of Indian Penal Code in so far as it criminalises consensual sexual acts of adults in private are violative of Articles 21,14, and 15 of the Constitution”.

2013: SC overturns Delhi HC’s order.

SC finds it “legally unsustainable”, “minuscule fraction of the country’s population constitutes LGBT”.
