Which legal concept allows Public Interest Litigation (PIL) to be filed in Indian courts by any public-spirited individual or organization, relaxing the traditional rule of 'locus standi'?

💡 Solution & Explanation

Epistolary jurisdiction describes the judicial innovation where Indian courts accept informal communications such as letters and postcards as writ petitions, thereby relaxing traditional rules of locus standi for public interest litigation. Other concepts like judicial restraint or the doctrine of severability apply to statutory interpretation and judicial review rather than relaxing access barriers for disadvantaged citizens. This relaxation democratized access to justice for marginalized groups who cannot approach courts through conventional litigation procedures.
