United States Supreme Court
242 U.S. 344
McNaughton v. Johnson
Argued: December 12, 1916. --- Decided: January 8, 1917
This case was submitted with Crane v. Johnson, just decided [[[242 U.S. 339]], 61 L. ed. 348, 37 Sup. Ct. Rep. 176]. It was considered in the district court with that case, three judges sitting as in that case. It comes here on appeal from an order denying an interlocutory injunction. The court entertained jurisdiction upon the authority of Raich v. Truax, 219 Fed. 273, 283; Truax v. Raich, 239 U.S. 33, 60 L. ed. 131, L.R.A. 1916D, 545, 36 Sup. Ct. Rep. 7.
The court, in denying the injunction, said 'that the granting of such orders is within the sound discretion of the court, and, in the exercise of such discretion, based upon the averments of the bills, we are of opinion that the application should be denied.' The court did not pass upon the merits, expressing a doubt of its authority to do so, as the court said it was composed of three judges, 'under statutory requirement.'
Appellant-we shall call her complainant, and state narratively the facts she alleged-is a regularly graduated ophthalmologist, which is a school of scientific learning and practice confined to the treatment of the inflammation of the eye and its membranes and in fitting glasses to the human eye. She has practised her profession in the city of Los Angeles for the past three years and is dependent upon the proceeds of her labor and services. She does not employ either medicine, drugs, or surgery, nor is there anything in her practice hurtful to the individual or dangerous to society.
In her practice it is absolutely necessary and indispensable that she measure the powers and range of human vision without the use of drugs, and there is no law in the state of California prescribing an examination for and regulating the practice of ophthalmology.
At its 40th session the legislature of California enacted a statute by which it provided that it should be unlawful for any person to engage in the practice of optometry without first having obtained a certificate of registration from the State Board of Optometry under an act to regulate that practice, approved March 20, 1903, and the acts amendatory thereof.
The practice of optometry is defined to be the employment of any means other than the use of drugs for the measurement of the powers or range of human vision, or the determination of the accommodative and refractive states of the human eye, or the scope of its functions in general, or the adaptation of lenses or frames for the aid thereof.
The board is given the power, among others, to visit schools where the science of optometry is taught, and accredit such as the board finds give a sufficient course of study for the preparation of optometrists; to keep a register of all persons to whom certificates of registration have been issued and of all itinerant licenses, and to grant or refuse or revoke such certificates. The act prescribes a course of examination, describes the particulars of the examinations, and provides that every applicant for an examination, upon passing it, shall be entitled to be registered in the board's register of optometrists, and a certificate of registration shall be issued to him.
'At such examinations the board shall examine applicants in the anatomy of the eye, in normal and abnormal refractive and accommodative and muscular conditions and co-ordination of the eye, in subjective and objective optometry, including the fitting of glasses, the principles of lens grinding and frame adjusting, and in such other subjects as pertain to the science and practice of optometry, such subjects to be enumerated in publication by the board. In case of failure, the applicant shall be examined at the next examination only in the subjects in which he failed. All such applicants, without discrimination, who shall satisfactorily pass such examination shall thereupon be registered in the board's register of optometrists and a certificate of registration shall be issued to them, under the seal and signature of the members of said board upon payment of a fee of $5. Such certificate shall continue in force until the first day of August in the year next succeeding.' [Stat. 1913, chap. 598, p. 1100.]
Before engaging in practice it shall be the duty of each registered optometrist to notify the board in writing of the place or places where he is to engage or intends to engage in practice, and of changes in such places.
There are other provisions intended to fortify those above mentioned, and violations of the act are made misdemeanors, with fines and imprisonment, increasing with repetition of the offense.
It is provided that the act shall not be construed to prevent duly licensed physicians and surgeons from treating the human eye, nor to prohibit the sale of complete ready-to-wear eyeglasses as merchandise from a permanent place of business, in good faith, and not in evasion of the act, by the person not holding himself out as competent to examine and prescribe for the human eye.
Registry certificates may be revoked for certain specified causes.
Complainant charges that the act offends the 14th Amendment of the Constitution of the United States in that it deprives her of her property without due process of law and denies her the equal protection of the laws; and as specifications of the last she instances the exemption from the provisions of the act of licensed physicians and surgeons; the appropriation to the sole use of registered optometrists of the right to employ any means other than the use of drugs in the measurement of the powers or range of vision; the denial to all other schools of scientific learning and practice the right to measure the range of human vision other than by the use of drugs on equal terms with the physician and surgeon; and contends generally that her occupation being a lawful one, not hurtful to the individual or dangerous to the community, the state has no power to impose discriminatory regulations upon it.
She alleges her competency to practise her profession and apply its treatment, that appellees are threatening to enforce the law, and hence prays temporary and permanent injunctions.
These specific objections are brought down to the general objection that the statute discriminates against those who employ any other means than the use of drugs, and therefore 'creates a monopoly favored and protected by law in the interest of practitioners who employ drugs in determining the accommodative and refractive states of the human eye.'
To sustain the statute appellees adduce the police power of the state; against the statute complainant urges the 14th Amendment and its prohibition of discrimination. The case requires, under the averments of the bill, adjustment of these contentions.
It is established that a state may regulate the practice of medicine, using this word in its most general sense. Dent v. West Virginia, 129 U.S. 114, 32 L. ed. 623, 9 Sup. Ct. Rep. 231; Hawker v. New York, 170 U.S. 189, 42 L. ed. 1002, 18 Sup. Ct. Rep. 573; Reetz v. Michigan, 188 U.S. 505, 47 L. ed. 563, 23 Sup. Ct. Rep. 390; Watson v. Maryland, 218 U.S. 173, 54 L. ed. 987, 30 Sup. Ct. Rep. 644; Collins v. Texas, 223 U.S. 288, 56 L. ed. 439, 32 Sup. Ct. Rep. 286.
Complainant tries to escape from the rulings of those cases by asserting a discrimination against her. She is an ophthalmologist, she avers, 'which is a school of scientific learning and practice confined to the treatment of the inflammation of the eye and its membranes and in fitting glasses to the human eye,' and that she has practised her profession for the past three years, and does not employ medicine, drugs, or surgery. She, however, attacks the statute because, to use the language of her counsel, it 'arbitrarily discriminates against every other school of scientific knowledge and practice in favor of the school employing drugs in determining the accommodative and refractive states of the human eye.' It undoubtedly does, but gives the name of the school that of 'optometry' and its practitioners 'optometrists.' We cannot suppose that any injury is done her by the difference in names, and yet she gives no other tangible ground of complaint. Whether they are different, and whether the difference is of substantial or unsubstantial degree, she does not inform us. She practises one of them in preference to the other, and for the practice of that one the state has declared that its certificate of competency is necessary. The cases cited above establish that the state has such power and it requires no more of complainant than it requires of any other ophthalmologist, to use her word, or of any other optometrist, to use the word of the statute.
The District Court was, therefore, right when it decided that, on the averments of the bill, complainant was not entitled to an injunction.
Decree affirmed.
