Such is the nature of the threat, and such the degree of coercion and intimidation involved in it.

If the defendants can lawfully perform the acts complained of in the city of Springfield, they can pursue the plaintiffs all over the State in the same manner, and compel them to abandon their trade or bow to the behests of their pursuers.

It is to be observed that this is not a case between the employer and employed, or, to use a hackneyed expression, between capital and labor, but between laborers all of the same craft, and each having the same right as any one of the others to pursue his calling. In this, as in every other case of equal rights, the right of each individual is to be exercised with due regard to the similar right of all others, and the right of one be said to end where that of another begins.

The right involved is the right to dispose of one’s labor with full freedom. This is a legal right, and it is entitled to legal protection. Sir William Erle in his book on Trade Unions, page 12, has stated this in the following language, which has been several times quoted with approval by judges in England: “Every person has a right under the law, as between him and his fellow subjects, to full freedom in disposing of his own labor or his own capital according to his own will. It follows that every other person is subject to the correlative duty arising therefrom, and is prohibited from any obstruction to the fullest exercise of this right which can be made compatible with the exercise of similar rights by others. Every act causing an obstruction to another in the exercise of the right comprised within this description—done, not in the exercise of the actor’s own right, but for the purpose of obstruction—would if damage should be caused thereby to the party obstructed, be a violation of this prohibition.”

The same rule is stated with care and discrimination by Wells, J., in Walker v. Cronin, 107 Mass. 555, 564: “Every one has a right to enjoy the fruits and advantages of his own enterprise, industry, skill, and credit. He has no right to be protected against competition; but he has a right to be free from malicious and wanton interference, disturbance, or annoyance. If disturbance or loss come as a result of competition, or the exercise of like rights by others, it is damnum absque injuria, unless some superior right by contract or otherwise is interfered with. But if it come from the merely wanton or malicious acts of others, without the justification of competition or the service of any interest or lawful purpose, it then stands upon a different footing.”

In this case the acts complained of were calculated to cause damage to the plaintiffs, and did actually cause such damage; and they were intentionally done for that purpose. Unless, therefore, there was justifiable cause, the acts were malicious and unlawful. Walker v. Cronin, ubi supra, Carew v. Rutherford, 106 Mass. 1, and cases cited therein.

The defendants contend that they have done nothing unlawful, and, in support of that contention, they say that a person may work for whom he pleases; and, in the absence of any contract to the contrary, may cease to work when he pleases, and for any reason whatever, whether the same be good or bad; that he may give notice of his intention in advance, with or without stating the reason; that what one man may do several men acting in concert may do, and may agree beforehand that they will do, and may give notice of the agreement; and that all this may be lawfully done notwithstanding such concerted action may, by reason of the consequent interruption of the work, result in great loss to the employer and his other employees, and that such a result was intended. In a general sense, and without reference to exceptions arising out of conflicting public and private interests, all this may be true.

It is said also that, where one has the lawful right to do a thing, the motive by which he is actuated is immaterial. One form of this statement appears in the first head-note in Allen v. Flood, as reported in [1898] A. C. 1, as follows: “An act lawful in itself is not converted by a malicious or bad motive into an unlawful act so as to make the doer of the act liable to a civil action.” If the meaning of this and similar expressions is that where a person has the lawful right to do a thing irrespective of his motive, his motive is immaterial the proposition is a mere truism. If, however, the meaning is that where a person, if actuated by one kind of a motive, has a lawful right to do a thing, the act is lawful when done under any conceivable motive; or that an act lawful under one set of circumstances is therefore lawful under every conceivable set of circumstances, the proposition does not commend itself to us as either logically or legally accurate.

In so far as a right is lawful, it is lawful, and in many cases the right is so far absolute as to be lawful whatever may be the motive of the actor, as where one digs upon his own land for water (Greenleaf v. Francis, 18 Pick. 117), or makes a written lease of his land for the purpose of terminating a tenancy at will (Groustra v. Bourges, 141 Mass. 7), but in many cases the lawfulness of an act which causes damage to another may depend upon whether the act is for justifiable cause; and this justification may be found sometimes in the circumstances under which it is done irrespective of motive, sometimes in the motive alone, and sometimes in the circumstances and motive combined.

This principle is of very general application in criminal law, and also is illustrated in many branches of the civil law, as in cases of libel and of procuring a wife to leave her husband. Tasker v. Stanley, 153 Mass. 148, and cases therein cited. Indeed the principle is a prominent feature underlying the whole doctrine of privilege, malice, and intent. See on this an instructive article in 8 Harvard Law Review, 1, where the subject is considered at some length.
