Concept:
Traditionally, only a person whose legal rights were directly violated could approach the court. This requirement is known as locus standi. To make justice accessible to disadvantaged sections of society, the Supreme Court gradually liberalized this rule through the development of Public Interest Litigation (PIL).
Step 1: Understanding traditional locus standi.
• Under the traditional rule, only the aggrieved person could file a petition.
• Third parties generally had no right to approach the court.
• This created difficulties for poor, illiterate, and marginalized citizens.
Step 2: Emergence of Public Interest Litigation.
• The Supreme Court, particularly during the late 1970s and 1980s, expanded access to justice.
• Public-spirited citizens, social activists, journalists, and NGOs were permitted to approach courts on behalf of affected groups.
• This innovation became known as Public Interest Litigation (PIL).
Step 3: Why Option (A) is correct.
• PIL is based upon the relaxation of locus standi.
• It allows courts to protect constitutional and fundamental rights even when victims themselves cannot approach the judiciary.
• Therefore, the development described in the question is directly connected with the evolution of PIL.
Relaxation of Locus Standi is the foundation of Public Interest Litigation in India.
