Satyadhyan Ghosal v Deorajin Debi

• Execution proceedings arose between a landlord and tenant
• At an earlier stage of the proceedings, an interlocutory order had been passed on a question of jurisdiction
• The order was not appealed by the affected party
• At a subsequent stage of the same proceeding, the same party attempted to reopen the jurisdictional question
• The issue was whether the earlier unappealed order operated as res judicata within the same proceeding

1. Whether the principle of res judicata under Section 11 CPC applies between different stages of the same suit or proceeding, or only between separate suits.

• The principle of res judicata is based on the need of giving finality to judicial decisions
• Once a res is judicata, it shall not be adjudged again
• The doctrine applies primarily between past litigation and future litigation, but it also applies between two stages in the same litigation
• A court having at an earlier stage decided a matter in one way will not allow the parties to reagitate the matter again at a subsequent stage of the same proceedings
• The earlier order, having attained finality by not being challenged, operates as res judicata on that point

Res judicata applies between stages of the same proceeding, not only between separate suits. An interlocutory order deciding a question finally, if not appealed, bars reopening that question at a later stage. The policy is finality of judicial decisions at every level.
