1. Water policy in India has effectively become water law as there is no comprehensive water law at the national level, only sectoral laws, and policies have directly shaped implementation and reforms.
2. The right to water is recognized in case law but drinking water policy, not law, has defined entitlements like 40 liters per capita per day.
3. There are challenges to using policy instead of law for governance as policies can be changed without formal legal process and may not comply with legal principles.
