Hari Mohan Sharma & Anr. v. Charanjeet Singh Rekhi & Ors. Etc.
Background
Two suits for specific performance of a property agreement were filed against a man named Charanjeet Singh Rekhi and his wife Manjit Kaur, who are based in Delhi and the United States. Two other, unrelated couples, who happened to also be named Charanjeet Singh Rekhi (one from Moradabad, one from Uttarakhand), applied to be added as parties, claiming it needed to be conclusively determined who the "real" defendants were. A single judge dismissed their applications, but the Delhi High Court's Division Bench reversed this and allowed them to be added, prompting an appeal to the Supreme Court.
Decision Breakdown
The Supreme Court held that a plaintiff in a civil suit is "dominus litis", the master of their own case, and gets to choose whom to sue; here the plaintiffs had clearly sued the Delhi-based Charanjeet Singh Rekhi and his wife, not the other same-named individuals. If it later turns out the chosen defendants have no connection to the underlying agreement, the suit (or its execution) will simply fail: that is a risk the plaintiff bears, but it does not make unrelated same-named persons necessary or proper parties to the suit. The Court distinguished a precedent cited by the respondents as resting on different facts (co-owners with a real stake in the property), restored the single judge's order, and set aside the Division Bench's judgment, allowing the appeal.
Lesson Learnt
A plaintiff controls who they sue in a civil suit; outsiders cannot force their way into litigation merely by claiming they share identifying details (like a name) with the actual defendant: they must pursue their own separate remedy if they believe they are wrongly affected.
