Impleadment under Order 1 Rule 10(2) requires necessity for effective adjudication, and reasoned orders must show that test.

Order 1 Rule 10(2) permits impleadment only where the proposed party is necessary for effective and complete adjudication of the controversy, meaning the relief sought must directly and legally affect that person rather than create only a commercial, evidentiary, or incidental interest. The impleadment orders lacked reasons showing how the writ petitioner met that test, so the basis for joinder was not disclosed. The orders were therefore held unsustainable, and the impleadment application was remitted for fresh consideration in accordance with law.

Issues: Whether the impleadment orders passed by the Debts Recovery Tribunal and the Debts Recovery Appellate Tribunal were sustainable in the absence of reasons showing that the writ petitioner was a necessary or proper party under Order 1 Rule 10(2) of the Code of Civil Procedure.

Analysis: Order 1 Rule 10(2) permits addition of a party only where the party's presence is necessary to enable the Court to effectually and completely adjudicate upon and settle all questions involved in the proceedings. The governing test is whether the relief sought would directly and legally affect the person sought to be impleaded, not merely whether that person has a commercial, evidentiary, or incidental interest in the subject matter. The orders under challenge did not record any reasons explaining how the writ petitioner satisfied that test, and therefore did not disclose the basis on which impleadment was justified.

Conclusion: The impleadment orders were unsustainable and were set aside, and the application for impleadment was directed to be reconsidered afresh in accordance with law.

Ratio Decidendi: A party can be impleaded under Order 1 Rule 10(2) only if its presence is necessary for effective and complete adjudication of the controversy, and an impleadment order must reflect reasons showing application of that test.
