It was formerly held, usually on the authority of McManus v. Crickett, 1 East 106, that a master was not answerable for the wilful or malicious act of his servant, though done in the line of the servant’s duties, unless he directed or assented to it. Accordingly, it was said by Aldis, J., in Andrus v. Howard, 36 Vt. 248, that “the master is not liable for the wilful wrong or trespass of the servant, though the act be done while employed in the business of his master.” But this doctrine is now pretty generally repudiated, and it has come to be well settled that a master is liable for the act of his servant, though it be wilful and malicious, when it is done in furtherance of the master’s business and within the scope of the servant’s employment. The primary test, then, is, not the character of the act itself, nor whether it was done during the period of employment, but whether it was done to carry out the directions of the master, express or implied, or to effect some purpose of the servant alone. This rule was fully recognized and approved in Palmer v. St. Albans, 60 Vt. 427, 13 Atl. 569, 6 Am. St. Rep. 125, wherein it is said: “The rule of respondeat superior is of universal application, whether the act be one, of omission or of commission, whether negligent or fraudulent. And it makes no difference that the master did not know of the act, or disapproved it, or even forbade it, provided the servant was acting at the time for the master and within the scope of the business entrusted to him. * * * But the foundation of the rule is the relation of master and servant. When that does not exist, the law does not impute to one man the negligence of another. * * * Hence, the modern cases all show that it is not enough in order to charge one man with the negligence of another, to show that the latter was acting at the time under the employment of the former; but you must go further and show that the employment created the relation of master and servant between them;” — that is to say, of course, the relation of master and servant as to the very act of which complaint is made. Acts are here spoken of as “negligent or fraudulent,” but in *256this connection fraud stands the same as other torts. Barwick v. English Joint Stock Bank, 2 L. R. Ex. Cas. at p. 265. So far we can proceed without much difficulty. Indeed the defendant’s brief does not seriously controvert the rule as above stated. But an attempt to apply the rule to the varying circumstances of the numberless cases which have already arisen under it has led to much perplexity and confusion. In Pollock’s Torts, (7th Ed.) at p. 82, the injuries in respect of which a master becomes subject to this kind of “vicarious liability” are helpfully classified as follows:
(a) Such as are the natural consequence of something being done by a servant with ordinary care in execution of the master’s specific orders.
(b) Such as are due to the servant’s want of care in carrying on the work or business in which he is employed.
(c) Such as result from an excess or mistaken execution of a lawful authority.
(d) Such as result from a wilful wrong, such as an assault, provided the act is done on the master’s behalf and with the intention of serving his purposes.
The case in hand falls within class c or class d. It is further said by the author referred to at p. 87, that to establish a right of action against the master in eases covered by class c, it must be shown that (1) the servant intended to do on behalf of his master something of a kind which he was in fact authorized to do; (2) the act, if done in a proper manner, or under circumstances erroneously supposed by the servant to exist, would have been lawful.
In determining what acts are within a servant’s authority, courts are not usually confined to his express instructions,- Regard should be had to the character of the work, the situation of the parties, and the surrounding circumstances. Certain implied authority goes yith the relation, usually if not always. In the much quoted language of Mr. Justice Blackburn in Allen v. London, etc. Ry. Co., L. R. 6 Q. B. 65, implied authority in a servant will be inferred to do all those things that were necessary for the protection of the property intrusted to him or for fulfilling the duty which he has to perform.
So this man Williams who was the defendant’s caretaker and had sole charge of his island in Lake Champlain, was clothed *257with implied authority to keep off trespassers and intruders,— and this, without regard to his written instructions that the defendant did not care to have people tie up to his wharf. Authority to use such force as might be necessary to accomplish this is implied from the character of the work. 26 Cyc. 1541; Alton Ry. & Illuminating Co. v. Cox, 84 Ill. App. 202; Brennan v. Merchant & Co., (Pa.) 54 Atl. 891. The' whole story is condensed into an admirable statement of Willis, J., in Bagley v. M. S. & L. R. R. Co., L. R. 7 C. P. at p. 420: “A person who puts another in his place to do a class of acts in his absence necessarily leaves him to determine, according to the circumstances that arise, when an act of that class is to be done, and trusts him for the manner in which it is done; and consequently he is held answerable for the wrong of the person so intrusted either in the manner of doing such an act, or in doing such an act under circumstances in which it ought not to have been done; provided that what was done was done, not from any caprice of the servant, but in the course of the employment.” When Williams cast off the plaintiff’s rope, he was doing one of a class of acts well within the scope of his employment. One which under ordinary circumstances would be proper and lawful. But in the peculiar circumstances then existing, the act was improper and unlawful, — it was done under circumstances in which it ought not to have been done, — and the defendant is responsible, whether it was done carelessly or wilfully, unless it was done from the caprice of Williams, that is, to serve some purpose of his own. In other words, if Williams cast off the rope intending thereby to carry out his instructions and perform his duty as caretaker of the property, the defendant is liable; if he cast it off, not for this purpose, but only to serve some purpose of his own, the defendant is not liable.
The books are crowded with cases supporting this doctrine, a few of which we take time to refer to by way of illustration:
In Letts v. Hoboken, etc. Co., (N. J.) 57 Atl. 392, the declaration charged that the defendant as owner of certain property employed a watchman to prevent persons from trespassing thereon, and that the watchman, within the scope of his employment and acting for the owner, in ejecting a person from the premises, made an assault upon him, from the effects of which he died. It was held that it stated a cause of action, — the court " *258saying, “authority given by the master to his servant to eject trespassers from the former’s premises charges the master with the liability for the act of the servant in using excessive or inap - propriate force in removing one who was a trespasser.”
In Brennan v. Merchant & Co., supra, a boy eight years old climbed onto a moving truck of the defendant, then in charge of a driver, and held on to a standard. The driver, without warning, struck the boy’s hand with his whip, and the boy fell off and was injured. The plaintiff was non-suited below, and this was held error. “If his act,” says the court, “in striking the boy was intended to remove him by force from the wagon, it would be the act of his employer, for which the latter would be responsible. If, on the other hand, the purpose of the driver was not to cause the boy to leave the wagon, but to inflict punishment upon him, to gratify the ill will of the driver, the defendant company is not responsible for the wrongful or tortious act.”
In Hammond v. Grand Trunk Ry. Co., 4 Ont. W. Repr. 530, a watchman was employed at a crossing to raise and lower the gate by means of a lever in a structure near by. He was to lower the gate while a train was passing, and raise it immediately afterwards. The plaintiff, a boy of sixteen, reached the crossing when the gate was down and stood leaning upon it while a train passed. After the train had gone by, he and his companions did not immediately remove their weight from it, as the watchman ascertained as he attempted to raise it. Whereupon he picked up a cinder and threw it towards the plaintiff, hitting him in the eye and destroying it. The court said that the act of throwing the cinder was one for which the master might or might not be answerable. “If the act were done out of mere malice and ill temper and to punish the boy, the company would not be answerable; but if it were done for the purpose of warning him to get off the bars so that they might be raised, then it is clear that they would be answerable, although the act done was a tort.”
In Alton Ry. & Illuminating Co. v. Cox, supra, the company had a small park near the city of Alton, which was used during the summer as a pleasure resort. At the time in question it was closed and in the charge of a superintendent who had orders to keep all persons out of it. He testified that in the *259acts complained of lie was obeying Ms instructions. Cox and some others entered the park, and were ordered out by the superintendent. They got into an altercation and the superintendent threw a stone at Cox which hit and injured him. It was held that it was apparent that the superintendent was acting for his master and in the performance of his duty as he understood it and not on account of any matter personal to himself, and a recovery was sustained.
The instruction of which the defendant complains and to which he excepted was that it was established by uncontradicted evidence that Williams east off the rope, and “that in so doing he was acting within the scope of his employment as a servant of the defendant. * * * * So that * * * the defendant stands as though he had been present and had himself done the act. # # *” The questions whether a servant acts within the scope of his employment and whether he acts in behalf of the master or in his own behalf are usually questions of fact and so are for the jury. Note to Goodloe v. Memphis etc. R. R. Co., (Ala.) 52 Am. St. Rep. at p. 85; ib. at p. 89. But this is not always so, and the usual rule prevails in these as in other eases: — If the facts and the inferences to be drawn therefrom are not in dispute, the court may dispose of these questions as matter of law. Brennan v. Merchant & Co., (Pa.) 54 Atl. 891. So it remains to inquire whether there was any conflict in the evidence on these important questions in the case in hand.
As we have already seen, the act of casting off the rope of one attempting to tie up to that wharf would, ordinarily, be within the scope of Williams’ employment. He testified that he threw the plaintiff’s line off in furtherance of his employer’s orders, and that he so informed the plaintiff at the time. The only evidence disclosed by the record which could in any view be claimed to have a tendency to contradict this, comes from Williams himself when he testifies that, after he told the plaintiff that the defendant did not allow boats to tie up there, the plaintiff swore at him, called him an opprobious name, and threatened him. There is nothing in this fact alone which tends to show that Williams thereupon cast off the rope for any purpose of his own. It does not appear that he was angered, or even irritated by it. And we cannot infer that he was in order to find error. Nothing appears to indicate that he had any personal interests *260to serve, or that in. the slightest degree, he turned aside from the line of duty as he then understood it or did anything that he would not have done. In these circumstances the court was right in the instruction given; the act being within the scope of the agency and done for the master’s benefit, the defendant’s liability was the same as if he had done it himself. Rochester v. Bull, 58 S. E. 766; Columbus R. R. Co. v. Woolfolk, (Ga.) 58 S. E. 152, 10 L. R. A. (N. S.) 1136.
In the foregoing discussion we have excluded from consideration (1) cases in which a special duty is imposed upon the master toward the person injured, arising out of the relation existing between them,- — like carrier and passenger, inn-keeper and guest, and such like; (2) cases in which an absolute duty is imposed upon the master, — by statute, for instance; and (3) eases in which the injuries result from certain dangerous agencies intrusted to the servant by the master, — like wild animgis or high explosives; all of which are said to be exceptions to the rules herein applied. Nor have we referred to cases in which the servant acts outside of the scope of his employment though attempting in good faith to further his master’s interests; which are said not to afford any ground of action against the master.
Judgment affirmed.
