Zainul vs State of Bihar - Mob Constructive Liability Case

Criminal Law October 7, 2025

Supreme Court clarifies when mob members can be convicted for murder under constructive liability - protecting innocent bystanders from false implication

❓ QUESTION

Can you be convicted for a murder committed by someone else, simply because you were part of a large crowd, even if you never raised a hand?

✅ ANSWER

Yes, but with crucial safeguards. The law holds every member of a violent mob responsible for crimes committed by the group. However, the Supreme Court has reinforced that this power cannot be used to convict innocent bystanders or passive onlookers. The prosecution must prove you were an active member of the unlawful mob, sharing its violent goal. Vague or contradictory evidence is not enough to prove guilt.

🧩 UNDERSTANDING THE LEGAL PRINCIPLES

⚖️ What the Supreme Court Has Clarified

1️⃣ The Law of "Constructive Liability" (Section 149 IPC)

This is the core legal principle. If five or more people form a mob (unlawful assembly) with a common violent goal (common object), and a crime is committed by any member to achieve that goal, every single member of that mob can be held guilty of that crime.

  • In Practice: If a mob's goal is to attack a person over a land dispute, and a member of the mob kills someone, every member who shared that violent goal can be convicted of murder, even if they didn't fire the shot.
  • The Court's Warning: This is a powerful legal tool. Courts must use it carefully to ensure that people who are merely curious spectators or innocent bystanders are not punished with the guilty.

2️⃣ Mere Presence is Not a Crime

The Court made a vital distinction:

  • Member of an Unlawful Assembly: A person who shares the mob's violent object and is part of it with the intention to further that goal. This person is liable.
  • Innocent Bystander/Passive Onlooker: A person who is present at the scene out of curiosity but does not share the mob's violent intention. This person is NOT liable.

The prosecution must provide strong evidence to show you were the former, not the latter.

3️⃣ The "Rule of Prudence" in Mob Violence Cases

When a large number of people are accused, the Court laid down a crucial rule of caution: The testimony of a single witness, if found unreliable, is not enough.

The prosecution's case becomes strong only when:

  • At least two or three reliable and consistent witnesses identify an accused person.
  • These witnesses attribute a specific role or action to that accused.
  • Their testimonies are consistent with each other and with medical evidence.

This rule protects against the "tendency to implicate as many persons as possible" in a faction-ridden case.

4️⃣ The Critical Role of Credible Witness Testimony

The Court emphasized that even the testimony of injured eyewitnesses, who are normally considered highly reliable, can be rejected if it is full of:

  • Material Contradictions: Major differences between what a witness told the police initially and what they said in court.
  • Embellishments: Exaggerations or adding new facts in court that were not mentioned earlier.
  • Conflict with Medical Evidence: If a witness claims they were attacked with a specific weapon, but their injuries tell a different medical story, their entire account becomes doubtful.

🧭 YOUR ACTION PLAN: NAVIGATING A CASE INVOLVING A "MOB" AND SECTION 149 IPC

📝 If You Are Challenging a Conviction (The Accused/Appellant)

✅ Step 1: Scrutinize the Witness Evidence

  • Compare Statements: Obtain the First Information Report (FIR) and the witnesses' initial statements to the police (under Section 161 CrPC). Compare them line-by-line with their court testimonies. Look for major omissions or new accusations that appear for the first time in court.
  • Check for Consistency Across Witnesses: If Witness A says you had a sword, but Witness B (who claims to have seen the same event) does not mention your weapon or presence, this inconsistency weakens the case against you.
  • Challenge the "Common Object": Argue that even if you were present, you did not share the mob's intention to kill or cause grievous hurt. Perhaps you were there by chance or to pacify the situation.

✅ Step 2: Challenge the "Unlawful Assembly" Itself

  • Argue You Were a Bystander: If the evidence against you is weak—for example, only one witness named you vaguely, without attributing a specific act—argue you were a passive onlooker caught in the event.
  • Invoke the "Rule of Prudence": Forcefully cite this judgment to argue that in a case with a large mob, your conviction cannot stand on the sole, inconsistent testimony of one witness. Demand that the prosecution meets the standard of multiple, consistent witnesses.

✅ Step 3: Scrutinize the FIR and Investigation

  • Question the FIR's Authenticity: If, as in this case, there is evidence that the police knew about the incident and spoke to witnesses before the official FIR was written, argue that the FIR is not the true "first information" but a concocted version drafted after deliberation.
  • Highlight Investigative Lapses: Point out if the investigation failed to explain why certain named individuals were dropped from the case or why no action was taken against others clearly involved.

⚖️ If You Are the Prosecution (The State)

✅ Step 1: Build a Watertight Case from the Start

  • Record Evidence Meticulously: Ensure that the initial statements of witnesses are recorded accurately and in detail. Any specific role, weapon, or action attributed to an accused must be noted at this earliest stage.
  • Corroborate, Corroborate, Corroborate: Do not rely on one or two witnesses. Gather multiple, independent accounts that consistently point to the accused's active participation in the mob.
  • Align Ocular and Medical Evidence: Ensure that the witnesses' description of the attack is consistent with the medical reports of the injuries on the victims.

✅ Step 2: Prove "Common Object" with Circumstantial Evidence

  • Demonstrate the Common Goal: Show that the accused persons came together armed with deadly weapons, which itself indicates a pre-meditated, violent common object.
  • Show Collective Action: Prove that the accused acted in unison, surrounding and attacking the victims, which shows a shared intention.

⚖️ KEY LEGAL PROVISIONS EXPLAINED

💡 CORE TAKEAWAY FROM THE SUPREME COURT

"The doctrine of constructive liability must not be so stretched as to lead to false implication of innocent bystanders."

The Supreme Court's judgment serves as a powerful shield for the innocent. It reminds the justice system that in the heat of a factional dispute or mob violence, there is a dangerous tendency to implicate as many people as possible. The law, while holding truly guilty mob members accountable, must be applied with extreme caution to ensure that the mere fact of a person's presence at a scene does not become a life sentence.
