The modern techni- cal designation, in the law of corporations, of acts beyond the scope of their powers, as defined by their charters or acts of in- corporation. A term used to express the action of a corporation which is beyond the powers conferred upon it by its charter, or the statutes under which it was instituted. 13 Am. L. Rev. 632. This doctrine is of modern growth; its appearance dates from about the year 1845, being first prominently mentioned in 10 Beav. 1 and 11 C. B. 775. See Green's Brice, Ultra Vires v 729. The general rule is that a contract by which a railroad company renders itself incapable of performing its duties to the public or attempts to absolve itself from those obligations without the consent of the state, or a contract made by a corpo- ration beyond the scope of its powers, ex- press or implied, on a proper construction of its charter, cannot be enforced, or ren- dered enforcible by the application of the doctrine of estoppel; but where the sub- ject-matter of the contract is not foreign to the purposes for which the corporation is created, a contract embracing whatever may fairly be regarded as incidental to, or consequential upon, these things which the legislature has authorized, ought not, un- less expressly prohibited, to be held, by judicial construction, to be ultra vires; 163 U. S. 564. When acts of corporations are spoken of as ultra vires, it is not intended that they are unlawful, or even such as the corpora- tion cannot perform, but merely those which are not within the powers conferred upon the corporation by the act of its crea- tíon, etc.; 68 N. Y. 68. A corporate act is said to be ultra vires when it is not with- in the scope of the powers of the corpora- tion to perform it under any circumstances, or for any purpose; or, with reference to the rights of certain parties, when the corporation is not authorized to perform it without their consent; or, with refer- ence to some specifio purpose, when it is not authorized to perform it for that pur- pose, though fully within the scope of the general powers of the corporation, with the consent of the parties interested, or for some other purpose; 43 Ia. 48. See 35 L. J. Ch. 156; 125 Mass. 333; 37 Cal. 543. As a general rule, such acts are void, and impose no obligation upon the corpora- tion although they assume the form of contracts; inasmuch as all persons deal- ing with a corporation, especially in the state or country in which and under whose laws it was created, are chargeable with notice of the extent of its chartered pow- ers. It is otherwise as to laws imposing restraints upon it not contained in its charter where the contract is made or the transaction takes place without the limits of the state or country under whose laws the corporation exists; 8 Barb. 233. Perhaps the most general statement of the doctrine of ultra vires is that a con- tract of a corporation which is unauthor- ized by, or in violation of, its charter or other governing statute, or entirely out- side of the scope of the purpose of its crea- tion, is void in the sense of being no con- tract at all, because of a total want of power to enter into it; such a contract will not be enforced by any species of action in a court of justice; being void ab initio, it cannot be made good by ratification, or by any succession of renewals; and no performance on either side can give val- idity to the unlawful contract, or form the foundation of any right of action upon it; 5 Thomp. Corp. § 5968. The artificial body-the corporation-is liable to be proceeded against by quo war- ranto for the usurpation of powers in its name by its officers and agents, and its charter may be taken away as a penalty for permitting such acts-the defence of a want of power to bind the corporation not being available in such cases, since it would lead to entire corporate irrespon- sibility; Moraw. Pri. Corp. § 649. A corporation has all the capacities for engaging in transactions and for manage- ment which are given it expressly by its charter, etc., or impliedly given it by reasonable implication from the language thereof. Capacities or powers for man- agement may be given by wide general language. Beyond these powers, they have no capacities or powers, and cannot legally engage in other transactions. In the United States the defence of ultra vires interposed against a contract wholly or in part executed has very gener- ally been looked upon with disfavor. The result has been that in some cases a liberal construction has been applied so as to destroy the foundation of the defence; in others the courts have allowed the recovery of the money paid, not upon the contract, but because of the money received and the benefits enjoyed; while in still an- other class of cases, the doctrine of estop- pel in pais has been applied to exclude the defence. The courts may be said, gener- ally, to be tending towards the doctrine- certainly so far as business corporations are concerned-that corporat
