Plaintiff, who is a physician and surgeon, was called in by defendants, and began to treat their *371employee, Cook, on March 8,1883. He continued to visit the patient until October 2,1883. On September 24th he made a demand upon defendants for the sum of $2,386. Thereupon defendants notified him that they considered his charges exorbitant, and that they would not be responsible for any further services in behalf of Cook. He then brought this action to recover the sum of $2,406, alleged to be the reasonable value of his services. The' jury found a verdict in his behalf for the sum of $1,800, and judgment was entered for that amount, and $318 costs and disbursements. The defendants moved for a new trial, specifying several errors of law, and claiming that the verdict was excessive. The defendants convinced the learned judge who heard and decided the motion that the verdict was excessive, and not warranted by the evidence, and he thereupon caused to be entered a conditional minute order, of which the following is a copy: “The motion for a new trial herein will be denied, provided that plaintiff, within thirty days from this date, offer to remit the sum of eight hundred dollars from the amount of the verdict herein; provided, also, that the defendants shall agree to accept said verdict and judgment so modified as a finality, said offer to remit not to be binding upon the plaintiff unless accepted by defendants as a finality. Said motion for a new trial to be granted unless said offer to remit by plaintiff be so made.”
In accordance with the order, plaintiff filed an offer to remit the sum of eight hundred dollars from the amount of the verdict, provided the defendants should accept the verdict and judgment so modified as a finality. The defendants elected not to accept the terms of the order, whereupon the court made an order denying the motion in the following language: “It appearing that plaintiff has offered to remit said sum as directed, and within the time directed, and no error appearing in the record, and the verdict as rendered being sustained by a pre*372ponderance of evidence, unless as to the amount of the verdict, it is hereby ordered that the motion for a new trial be and the same is hereby denied.”
We are of opinion that the court erred in denying the motion. If the verdict was for an excessive amount, and it is made clear by the language of both orders that the court believed it was,— and the evidence, we think, fully sustains the court in such belief,—defendants were entitled to have it reduced without the imposition of any terms upon them, and wfithout being deprived of the right to correct any errors leading to a judgment which, although supported by the evidence admitted, is nevertheless erroneous. It was not the fault of defendants that the jury found the value of plaintiff’s services to be nearly double what the court thought the evidence showed it to be, and they ought not to be punished because the jury erred. The court was of opinion that no errors had been committed during the trial, but that the verdict was for eight hundred dollars in excess of what the defendants justly owed the plaintiff. Hence its order, in effect, is a penalty of eight hundred dollars against the defendants, if they fail to accept the rulings of the court, made during the trial, as just and final. Further along we shall find a practical illustration of the injustice which would result if this could be done. The court admitted evidence as to the value of services for which plaintiff was not under any circumstances entitled to recover.
At the time plaintiff was employed by defendants he had not procured the certificate required by the laws of this state regulating the practice of medicine. (“ An act to regulate the practice of medicine,” Stats. 1875-76, p. 792, and an act supplemental thereto, Stats. 1877-78, p. 918.) By section 13 of the first act it is provided that “ any person practicing medicine or surgery in this state, without complying with the provisions of this act, shall be punished by a fine of not less than fifty dollars, *373and not more than five hundred dollars, or be imprisoned in the county jail for a period of not less than thirty days, nor more than three hundred and sixty-five days, or by both such fine and imprisonment, for each and every offense.” And by section 7 of the amendatory act of 1878, a person practicing medicine without having first procured a certificate from one of the medical boards is guilty of a misdemeanor, and subject to the penalties provided in section 13 of the act of 1876. By the terms of section 6 he is required to have his certificate recorded in the office of the cleric of the county in which he resides. The plaintiff’s application was not granted by the board of examiners until March 12th, and his certificate was not received by him until March 21st; it was recorded March 29th.
Under the law referred to and the facts, we think the court erred in refusing the first instruction of defendant, to the effect that plaintiff was not entitled to recover from defendants any compensation for medical services rendered between March 3 and March 12, 1888. “The general proposition is well established, that a contract founded on an illegal consideration, or which is made for the purpose of furthering any matter or thing prohibited by statute, or to aid or assist any party therein, is void. This rule applies to every contract which is founded on a transaction malum in se, or which is prohibited by statute, on the ground of public policy.” (Swanger v. Mayberry, 59 Cal. 91; Ladda v. Hawley, 57 Cal. 51.) This principle is in accord with the express provision of our Civil Code, which makes that unlawful which is either contrary to the express provision of law, or “contrary to the policy of express law, though not expressly prohibited.” (Civ. Code, sec. 1667.) In construing the acts above referred to, this court said in Ex parte Frazier, 54 Cal. 94: "The title of the act sufficiently indicates its main purpose and design. Its general framework shows that it was intended to require of those alone *374authorized to practice that knowledge of pathology, anatomy, and physiology recognized as necessary by every school of the science of medicine.” And this being the main object of the law, it must follow that it is the policy of the law to protect the public health, and prevent imposition upon those in need of medical advice and care. A contract made, therefore, to render medical services with one who has not obtained a certificate, showing that he possesses the necessary qualifications, — who has not complied with the law,-—is contrary to such policy, and is therefore void.
It is claimed on behalf of appellant that the contract Avas an entire contract, and if void in part, was void in toto. This contention, we think, cannot be sustained. The contract was an implied one. The law implied a promise to pay for each visit as it was made. The most that can be said in support of the contention is, that the law Avill not imply a promise to pay for services which have been illegally rendered. This objection can apply only to such services as were rendered prior to March 12th, when plaintiff obtained his certificate. There was no violation of the law in any services rendered by the plaintiff subsequent to that date, and there is no reason why the law should not imply a promise to pay for them. It is claimed by respondent that the court under this view should order the amount recovered for services prior to March 12th to be remitted, and sustain the judgment for the remainder. Instruction No. 1, offered by defendant and refused, shows that the case was tried in the court below upon the theory that the plaintiff could recover for services rendered during the entire period of his employment; and it does not appear with sufficient clearness, we think, what was the value of the services rendered from March 3d to March 12th.
Respondent claims that the issuance to the plaintiff of a certificate on March 12th related back to the time when he made his application, which was prior to the *375date of his employment, and that this relation rendered the services valid. This contention, we think, cannot be sustained. (Ladda v. Hawley, supra.)
We think that the court erred in allowing the plaintiff to testify as to discoveries he made in skin-grafting while caring for the patient, Cook. We are unable to see what bearing upon the question of the liability of the defendants this testimony would have. They certainly could not be made liable for any extraordinary services performed in experimenting upon the patient for the purpose of discovering new and improved methods of treatment in skin-grafting. The question was furthermore objectionable, on the ground that it called for the opinion of the witness as to the discoveries made, not as to what he had actually, done.
It was error, also, we think, to allow the witness Cook to state what was the result of Dr. Worth’s treatment. The value of the plaintiff’s services in no way depended upon the nature or value of Dr. Worth’s treatment. If Dr. Worth’s treatment was bad, that fact did not make Dr. Gardner’s any better.
Judgment and order reversed, and cause remanded for a new trial.
