Where the parties are numerous and the suit is for an object common to all, some of them may maintain or defend a bill in equity for all.¹ 2. To receive approval: as, for a bill, an act, a law, to pass one or both houses of legislation, and be signed by the Executive.l An act of a legislature is "passed" only when it has gone through the forms necessary by the constitution to give it validity as a binding rule of conduct. Its passage dates from the time when it ceases to be a mere proposition or bill, and passes into a law.1 The reference may be to the time when the act is to take effect.2 See Аст, 3. To a bill in equity there are three classes of parties: (1) Formal parties. (2) Persons having an interest in the controversy, and who ought to be made parties, that the court may act on the rule which requires it to finally determine the entire controversy and do complete justice, by adjusting all the rights involved in it. These are necessary parties; but if their interests are separable from those of the parties before the court, so that the court can proceed to a decree, and do complete and final justice, without affecting other to pass a case. parties not before the court, the latter are not indispensable parties. (3) Persons who not only have an interest in the controversy, but an interest of such a nature that a final decree cannot be made without either affecting that interest or leaving the controversy in such a condition that its final termination may be wholly inconsistent with equity and good conscience.2 As to parties defendant, in particular, all whose interests will be affected by the decree sought must be before the court. If they cannot be reached by process, or do not voluntarily appear, or from a jurisdictional objection cannot be made parties, the bill must be dismissed. The exact distinction may be stated thus: (1) Where a person will be directly affected by a decree, he is an indispensable party, unless the parties are too numerous to be brought before the court, when the case is subject to a special rule. (2) When a person is interested in the controversy, but will not be directly affected by a decree made in his absence, he is not an indispensable party, but he should be made a party, if possible, and the court will not proceed to a decree without him if he can be reached. (3) Where he is not interested in the controversy between the immediate litigants, but has an interest in the subject-matter which may be conveniently settled in the suit, and thereby prevent further litigation, he may be made a party or not at the option of the complainant. But no proceeding will prejudice a party who cannot be found.
