Gross indecency

 is a term used in some criminal statutes to criminalize certain forms of sexual activity. Its definition varies by jurisdiction.

The term "gross indecency" originated in the United Kingdom with the Labouchere Amendment&mdash;Section 11 of the Criminal Law Amendment Act 1885, introduced by Henry Labouchere, Liberal MP for Northampton&mdash;which was passed by Parliament. The amendment did not define what constituted gross indecency, but it specified that it involved acts between at least two men.

British colonies, Section 377
The Labouchere Amendment were exported by the British to several of its colonies. It was first codified as Section 377 in the Indian Penal Code as "carnal intercourse against the order of nature" in 1860. It was then adopted by other former British colonies. Due to the common origin of historical penal codes in many former British colonies, the prohibition of homosexual acts, specifically anal sex between men, is provided for in Section 377 in the penal codes of 42 former British colonies. The British have contributed nearly half of all gross indecency laws that were still in place in 2006 (42 out of 92). Today, homosexual activity remains a criminal offence in 35 of the 54 sovereign states of the Commonwealth; and legal in only 19.

India
India has Section 377 on September 6, 2018.

Singapore
The introduction of S377 to Singapore's Penal Code was not due to homophobia, but instead racism; at this time, it was disgraceful to the British to learn that European men were consorting with "Asian male prostitutes". Following a penal code review in 2007, the original Section 377 was repealed, with a new Section 377 taking its place. The new section was used to criminalize necrophilia, while Section 377a would be used for homosexual relations. Section 377a as it currently reads states:

"Any male person who, in public or private, commits, or abets the commission of, or procures or attempts to procure the commission by any male person of, any act of gross indecency with another male person, shall be punished with imprisonment for a term which may extend to 2 years."

While it is said that it is enforced, S377 is used as a foundation to justify several government policies that discriminate against LGBTQIA+ people in Singapore. There have been three court cases raised regarding the constitutionality of S377; the first was in 2010, the second occurred in 2012, and the third in 2018. The need for the legislation had been questioned in August 2018 after India repealed S377 in its own penal code.

In early 2020, the High Court dismissed all three challenges, with two of the plaintiffs appealing immediately.

Pink Dot SG, Singapore's pride event, first organized in 2009 strives to unite people under the slogan, "Freedom to Love" continues to advocate for the repeal of S377a.
