Step 1: Definition: An Advocate-on-Record (AoR) is a legal professional authorized to file pleadings and appear before the Supreme Court of India. Step 2: Exclusive Right: Only Advocates-on-Record can file cases directly in the Supreme Court; other advocates can only appear through them. This rule ensures proper handling of Supreme Court litigation. Step 3: Qualifications: To become an AoR, an advocate must undergo specific examinations and training as per Supreme Court Rules. Step 4: Jurisdiction: Advocates for High Courts and District Courts do not have the right to file directly before the Supreme Court unless qualified as AoR. Hence, an Advocate-on-Record can file cases before the Supreme Court of India exclusively.
