Adversarial vs Inquisitorial System

Landmark Case: Salem Advocate Bar Association v. Union of India (2005) 6 SCC 344 — The Supreme Court declared Section 89 CPC mandatory. Every civil court must try ADR first.

The Adversarial System

Meaning: A “fight-based” system. Two opposing lawyers argue before a passive judge who acts as neutral umpire. Used in India, UK, USA.

Key Features

• Two parties fight as opponents.
• Each side presents its own evidence and witnesses.
• The judge is passive — just listens and decides.
• Strict rules of evidence and procedure.
• Cross-examination is the heart of the trial.

Advantages

• Fair to both parties (equal chance to argue).
• Lawyers do thorough preparation.
• Protects rights of the accused (audi alteram partem).
• Public trial = transparency.

Disadvantages

• Slow and expensive.
• Truth may lose to better lawyering.
• Promotes hostility, not harmony.
• Judge cannot ask questions freely.

The Inquisitorial System

Meaning: A “search-based” system. The judge is the active investigator who finds the truth. Used in France, Germany, Italy.

Key Features

• Judge actively investigates, asks questions, calls witnesses.
• Lawyers are assistants, not gladiators.
• The case file (dossier) is supreme.
• Focus: discover the truth, not win a contest.

Advantages

• Faster and cheaper.
• Judge controls the case — fewer delay tactics.
• Truth-seeking, not adversarial.

Disadvantages

• Judge may become biased (“I already investigated”).
• Less protection for the accused.
• Heavy burden on the judge.

Sample Problem (KSLU-style)

Problem: India follows the adversarial system. A criminal trial is underway. The judge notices a key document lying on the table but neither lawyer mentions it. The judge wants to rely on it for his verdict. Can he?

Answer (IRAC):

• Issue: Whether a judge in an adversarial system can suo motu [on his own motion] rely on evidence not produced by either party.
• Rule: In the adversarial system, the judge is a passive umpire. The Indian Evidence Act, 1872 (Section 165) allows a judge to ask questions but only to clarify — not to fill gaps in a party’s case. The ultimate finder of fact remains the party’s evidence.
• Analysis: The judge has wide powers under Section 165 to “ask any question in any form at any time of any witness or party” — but this power is meant to clarify, not to substitute for a party’s duty to produce evidence. Relying on a document not formally tendered in evidence would violate the rule of natural justice — the opposing party has had no chance to cross-examine on it.
• Conclusion: The judge cannot rely on the document without first having it formally marked as an exhibit through one of the parties. To do otherwise would be a procedural irregularity and potentially a ground of appeal.
