A bench of justices G S Singhvi and S J Mukhopadhaya set aside the Delhi High Court's verdict which had in 2009 decriminalised gay sex among consenting adults in private.
The bench allowed the appeals filed by various social and religious organisations challenging the high court verdict on the ground that gay sex is against the cultural and religious values of the country.
The bench, however, put the ball in Parliament's court to take a decision on the controversial issue, saying it is for the legislature to debate and decide on the matter.
As soon as the verdict was pronounced, gay activists in the court looked visibly upset.
