(b) Joinder of Defendants (Order I Rule 3):

All persons may be joined as defendants against whom any right to relief arises out of the same act or transaction or series of acts or transactions, and common questions of law or fact would arise.

Non-Joinder: Failure to join a person who ought to have been joined as a party.

Necessary and Proper Parties

Necessary Party: A person whose presence is essential for adjudication and without whom no effective decree can be passed.


Proper Party: A person who, though not necessary, has an interest in the subject matter which may be affected by the decree.

Effect of Non-Joinder and Misjoinder : Order I Rule 9


No suit shall be defeated by reason of the misjoinder or non-joinder of parties. The court may deal with the matter in controversy so far as regards the rights and interests of the parties actually before it. The court may order that the name f any person improperly joined be struck out, and any person who ought to have been joined be added as a party.
However, the suit will be liable to be dismissed if there is a non-joinder of a necessary party and the court cannot adjudicate the matter without such party.

The court may at any stage of a suit either upon or without the application of any party order that the name of any party be struck out or that the name of any person who ought to have been joined be added. But no person shall be added as a plaintiff without his consent.
