Cover
- Right to life: Rural Litigation and Entitlement Kendra (1985, Doon Valley) and Subhash Kumar (1991) read pollution-free air and water into Article 21.
- Directive and duty: Article 48A binds the State and Article 51A(g) every citizen to protect the environment.

- Procedure and community: continuing mandamus in T. N. Godavarman (1996); Niyamgiri gram sabhas in Orissa Mining Corporation (2013).
