Plaintiff filed an ejectment suit under transfer of property act 106 against a partnership firm. Suit was held for 3 years and suit of the plaintiff was decreed by giving three months time. After completing three months time, plaintiff filed an execution suit under Order 21 Rule 11 of CPC. In this execution suit, plaintiff (petitioner) included a person as a respondent who was not in the main suit(ejectment suit). So, please can we take any defense in this execution case?
