In December 2013 a two-judge Supreme Court Bench set aside the Delhi High Court's Naz Foundation judgment and restored Section 377 IPC in full, re-criminalising consensual same-sex conduct between adults. A digest of the appeal, the Court's reasoning on Articles 14, 15 and 21, and how Koushal was first criticised in Puttaswamy and finally overruled in Navtej.
On 6 September 2018, a five-judge Constitution Bench unanimously read down Section 377 of the Indian Penal Code in so far as it criminalised consensual sexual conduct between adults. The judgment overruled Suresh Kumar Koushal (2013), deployed the Puttaswamy privacy framework, and supplied four substantial concurring opinions on dignity, equality and constitutional morality. A digest of the holding, the reasoning, and the doctrinal lineage.
