Explanation:

The landmark Supreme Court case of Gian Kaur v. State of Punjab (1996) primarily dealt with the constitutional validity of Section 309 of the Indian Penal Code (attempt to commit suicide) and Section 306 of the Indian Penal Code (abetment of suicide). The Court upheld the constitutionality of both sections, ruling that the 'right to life' under Article 21 does not include a 'right to die.' While it relates to both, the initial challenge and the overruling of a previous judgment (P. Rathinam) were centered on Section 309.
