Explanation VI extends res judicata to representative suits — when someone litigates a public or common right on behalf of a class, the outcome binds all members of that class, not just the named parties. This prevents re-litigation of public interest matters.

1. 1 Pick up CPC.
2. 2 Go to Section 11 (Res Judicata).
3. 3 Check Explanation V → about co-defendants. Not this.
4. 4 Check Explanation VI → 'Where persons litigate bona fide in respect of a public right or private right claimed in common... all persons interested shall be deemed to claim under the persons so litigating.' ✓ This applies res judicata to representative suits.
5. 5 No need to check VII and VIII.

The text reads: Explanation VI to Section 11: When persons litigate bona fide for a public or common right, all interested persons are deemed to claim under them (res judicata binds everyone).
