These considerations lead to the conclusion that the protection afforded to thoughts, sentiments, and emotions, expressed through the medium of writing or of the arts, so far as it consists in preventing publication, is merely an instance of the enforcement of the more general right of the individual to be let alone. It is like the right not to be assaulted or beaten, the right not to be imprisoned, the right not to be maliciously prosecuted, the right not to be defamed. In each of these rights, as indeed in all other rights recognized by the law, there inheres the quality of being owned or possessed – and (as that is the distinguishing attribute of property) there may be some propriety in speaking of those rights as property. But, obviously, they bear little resemblance to what is ordinarily comprehended under that term. The principle which protects personal writings and all other personal productions, not against theft and physical appropriation, but against publication in any form, is in reality not the principle of private property, but that of an inviolate personality.32
If we are correct in this conclusion, the existing law affords a principle which may be invoked to protect the privacy of the individual from invasion either by the too enterprising press, the photographer, or the possessor of any other modern device for recording or reproducing scenes or sounds. For the protection afforded is not confined by the authorities to those cases where any particular medium or form of expression has been adopted, nor to products of the intellect. The same protection is afforded to emotions and sensations expressed in a musical composition or other work of art as to a literary composition; and words spoken, a pantomime acted, a sonata performed, is no less entitled to protection than if each had been reduced to writing. The circumstance that a thought or emotion has been recorded in a permanent form renders its identification easier, and hence may be important from the point of view of evidence, but it has no significance as a matter of substantive right. If, then, the decisions indicate a general right to privacy for thoughts, emotions, and sensations, these should receive the same protection, whether expressed in writing, or in conduct, in conversation, in attitudes, or in facial expression.
It may be urged that a distinction should be taken between the deliberate expression of thoughts and emotions in literary or artistic compositions and the casual and often involuntary expression given to them in the ordinary conduct of life. In other words, it may be contended that the protection afforded is granted to the conscious products of labor, perhaps as an encouragement to effort.33 This contention, however plausible, has, in fact, little to recommend it. If the amount of labor involved be adopted as the test, we might well find that the effort to conduct one's self properly in business and in domestic relations had been far greater than that involved in painting a picture or writing a book; one would find that it was far easier to express lofty sentiments in a diary than in the conduct of a noble life. If the test of deliberateness of the act be adopted, much casual correspondence which is now accorded full protection would be excluded from the beneficent operation of existing rules. After the decisions denying the distinction attempted to be made between those literary productions which it was intended to publish and those which it was not, all considerations of the amount of labor involved, the degree of deliberation, the value of the product, and the intention of publishing must be abandoned, and no basis is discerned upon which the right to restrain publication and reproduction of such so-called literary and artistic works can be rested, except the right to privacy, as a part of the more general right to the immunity of the person, – the right to one's personality.
It should be stated that, in some instances where protection has been afforded against wrongful publication, the jurisdiction has been asserted, not on the ground of property, or at least not wholly on that ground, but upon the ground of an alleged breach of an implied contract or of a trust or confidence.
Thus, in Abernethy v. Hutchinson, 3 L. J. Ch. 209 (1825), where the plaintiff, a distinguished surgeon, sought to restrain the publication in the "Lancet" of unpublished lectures which he had delivered at St. Batholomew's Hospital in London, Lord Eldon doubted whether there could be property in lectures which had not been reduced to writing, but granted the injunction on the ground of breach of confidence, holding "that when persons were admitted as pupils or otherwise, to hear these lectures, although they were orally delivered, and although the parties might go to the extent, if they were able to do so, of putting down the whole by means of short-hand, yet they could do that only for the purposes of their own information, and could not publish, for profit, that which they had not obtained the right of selling."
In Prince Albert v. Strange, 1 McN. & G. 25 (1849), Lord Cottenham, on appeal, while recognizing a right of property in the etchings which of itself would justify the issuance of the injunction, stated, after discussing the evidence, that he was bound to assume that the possession of the etchings by the defendant had "its foundation in a breach of trust, confidence, or contract," and that upon such ground also the plaintiff's title to the injunction was fully sustained.
In Tuck v. Priester, 19 Q.B.D. 639 (1887), the plaintiffs were owners of a picture, and employed the defendant to make a certain number of copies. He did so, and made also a number of other copies for himself, and offered them for sale in England at a lower price. Subsequently, the plaintiffs registered their copyright in the picture, and then brought suit for an injunction and damages. The Lords Justices differed as to the application of the copyright acts to the case, but held unanimously that independently of those acts, the plaintiffs were entitled to an injunction and damages for breach of contract.
In Pollard v. Photographic Co., 4 °Ch. Div. 345 (1888), a photographer who had taken a lady's photograph under the ordinary circumstances was restrained from exhibiting it, and also from selling copies of it, on the ground that it was a breach of an implied term in the contract, and also that it was a breach of confidence. Mr. Justice North interjected in the argument of the plaintiff's counsel the inquiry: "Do you dispute that if the negative likeness were taken on the sly, the person who took it might exhibit copies?" and counsel for the plaintiff answered: "In that case there would be no trust or consideration to support a contract." Later, the defendant's counsel argued that "a person has no property in his own features; short of doing what is libellous or otherwise illegal, there is no restriction on the photographer's using his negative." But the court, while expressly finding a breach of contract and of trust sufficient to justify its interposition, still seems to have felt the necessity of resting the decision also upon a right of property,34 in order to bring it within the line of those cases which were relied upon as precedents.35
This process of implying a term in a contract, or of implying a trust (particularly where the contract is written, and where there is no established usage or custom), is nothing more nor less than a judicial declaration that public morality, private justice, and general convenience demand the recognition of such a rule, and that the publication under similar circumstances would be considered an intolerable abuse. So long as these circumstances happen to present a contract upon which such a term can be engrafted by the judicial mind, or to supply relations upon which a trust or confidence can be erected, there may be no objection to working out the desired protection through the doctrines of contract or of trust. But the court can hardly stop there. The narrower doctrine may have satisfied the demands of society at a time when the abuse to be guarded against could rarely have arisen without violating a contract or a special confidence; but now that modern devices afford abundant opportunities for the perpetration of such wrongs without any participation by the injured party, the protection granted by the law must be placed upon a broader foundation. While, for instance, the state of the photographic art was such that one's picture could seldom be taken without his consciously "sitting" for the purpose, the law of contract or of trust might afford the prudent man sufficient safeguards against the improper circulation of his portrait; but since the latest advances in photographic art have rendered it possible to take pictures surreptitiously, the doctrines of contract and of trust are inadequate to support the required protection, and the law of tort must be resorted to. The right of property in its widest sense, including all possession, including all rights and privileges, and hence embracing the right to an inviolate personality, affords alone that broad basis upon which the protection which the individual demands can be rested.
