The Centre on Wednesday left it to the wisdom of the Supreme Court to examine the constitutional validity of the penal provision, which criminalises "consensual acts of adults in private", saying this was the only question under Section 377 of the IPC, which needed to be decided by the constitution bench.

In an affidavit, the Ministry of Home Affairs said if the apex court decided to examine any question other than the constitutional validity of Section 377, it would have far-reaching and wide ramifications under other laws. Section 377 refers to 'unnatural offences' and says whoever voluntarily has carnal intercourse against the order of nature with any man, woman or animal, shall be punished with imprisonment for life, or with imprisonment of either description for a term which may extend to 10 years, and shall also be liable to pay a fine.
