A bill of discovery has a well known and universally recognized meaning in the law, and, in the absence of anything in the statute to the contrary, it is but fair to presume that the legislature intended to use the term in its generally accepted legal sense. In that sense it is a mere instrument of procedure in aid of relief sought by the party in some other judicial controversy, filed for the sole purpose of proving the plaintiff’s case from the defendant’s own mouth, or from documents in his possession, and asking no relief in the suit except it may be a temporary stay of the proceedings in another suit to which the discovery relates: Pomeroy’s Equity Jurisprudence, § 191. As so construed, the design of the statute is to authorize the governor to direct the district attorney to file an information or bill of discovery whenever he is in possession of facts the averment of which -Would support such a proceeding, and not otherwise. This is strengthened by the fact that before the governor can direct the proceedings to be commenced he must be informed or have reason to believe that the bank
In the language of Mr. Daniel, it must state “the matter touching which discovery is sought, the interest of the plaintiff and defendant in the subject, and the facts and circumstances upon which the right of the plaintiff to require the discovery from the defendant is founded”: 2 Daniel’s Chancery Pleading and Practice (6th Am. ed.),'"T557. And Mr. Story says that “If the bill does not show such a case as renders the discovery material to support or defend a suit, it is plainly not a case for the interposition of the court. Therefore, where a plaintiff filed a bill for a discovery merely to support an action, which he alleged by his bill he intended to commence in a court of common law, although by this allegation he brought his case within the jurisdiction of a court of equity to compel a discovery, yet, the court being of the opinion that the case stated by the bill was not such as would support an action at law, a demurrer was allowed. For, unless the plaintiff had a title to recover in an action at law, supposing his case to be true, he had no title to the assistance of a court of equity to obtain from the confession of the defendant evidence of the truth of the case”: Story’s Equity Pleading, § 319. And by Mr. Pomeroy it is said, “The plaintiff in the discovery suit must show by his averments, at least in a prima, fade manner, that if he is the plaintiff in the action at law he has a good cause of action, and if he is the defendant, he has a good defense thereto”: Pomeroy's Equity Jurisprudence, § 198. And in Mayor of London v. Levy, 8 Vesey, Jr., 398, Lord Chancellor Eldon, in enforcing the rule that the bill must set forth with reasonable certainty the nature of the action which is bi’ought, or, if not brought, the nature of the claim or
Applying these rules to the case before us, the bill must fail. It does not purport to show that the plaintiff has a cause of action against the defendant, but discloses on its face, both by averment and by the interrogatories, that it is simply searching for one. The averments are that the proposed action cannot be commenced until the plaintiff learns from the defendant “the name of the depositor, the amount and nature of the deposit, and date of deposit of such funds or other property as are now in the possession of the defendant, which have escheated to the state,” and that such action is to be “for the recovery of such sums or other property as may be found in the custody of said defendant bank.” It is true the information alleges that divers and sundry depositors
