This case has been before this court before. The opinion will be found reported in 188 Mich., at page 504 (154 N. W. 565). When first considered in the court the sole question for determination was whether under an undisputed statement of facts the circuit court had jurisdiction to try the case, or whether plaintiff’s sole remedy was under Act No. 10, Extra Session 1912 (2 Comp. Laws 1915, § 5423 et seq.), commonly known as the workmen’s compensation act.
By its plea to the jurisdiction defendant asserted that, by operation of law, plaintiff at the time the accident happened was under the act, and second, that if this was not so plaintiff had placed himself under the operation of the act by voluntarily filing a claim with the industrial accident board for compensation under the act.
We there held that inasmuch as the 30 days within which plaintiff, an employee, might have elected whether or not he would come under the terms of the act, had not expired at the time of the accident, he was not bound by its terms. We further held that his conduct in voluntarily seeking compensation under the act did not work an estoppel. The judgment overruling the plea in abatement was affirmed. ' Upon a new trial upon the merits, which this court had ordered, defendant was denied the right to introduce any defenses to the action, and the case was submitted to the jury simply for the purpose of computing plain*499tiffs damages which were assessed at the sum of $9,000. The judgment entered upon such verdict is now here for review.
Section 1 of the act is as follows:
“In an action to recover damages for personal injury sustained by an employee in the course of his employment, or for death resulting from personal injuries so sustained, it shall not be a defense:
“(a) That the employee was negligent, unless and except it shall appear that such negligence was wilful;
“(b) That the injury was caused by the negligence of a fellow employee;
“(c) That the employee had assumed the risks inherent in or incidental to, or arising out of his employment, or arising from the failure of the employer to provide and maintain safe premises and suitable appliances.”
Section 2 provides that the provisions of section 1 shall not apply to actions to recover damages for personal injuries sustained by household domestic servants and farm laborers.
Section 3 is as follows:
“The provisions of section one shall not apply to actions to recover damages for the death of, or for personal injuries sustained by employees of any employer who has elected, with the approval of the industrial accident board hereinafter created, to pay compensation in the manner and to the extent hereinafter provided.”
Section 6 is in part as follows:
“Such election on the part of the employers mentioned in subdivision two of the preceding section, shall be made by filing with the industrial accident board hereinafter provided for, a written statement to the effect that such employer accepts the provisions of this act, and that he adopts, subject to the approval of said board, one of the four methods provided for the payment of the compensation hereinafter specified; The filing of such statement and the approval of said board shall operate, within the meaning of the *500preceding section, to subject such employer to the provisions of this act and all acts amendatory thereof for the term of one year from the date of the filing of such statement.”
Reading these three sections together it is obvious that it was the intention of the legislature (indeed section 6 so states in plain language), to place an employer under the operation of the act from the day of the filing of the statement as soon as the approval of the board was given to said application. Such approval, when given by the terms of the statute, operates retroactively and fixes the status of the employer as being under the act, “from the date of the filing of the statement.” We, therefore, have the situation here in which the employer at the time of the accident was under the act and the employee (not having had an opportunity for election) was not under the act. This situation is exactly covered by section 3, which declares that the provision of section 1 shall not apply to such actions. In other words, the common-law defenses withdrawn by section 1 are open to the employer when he is under the act and the employee either voluntarily or involuntarily is not under the act.
The purpose of the legislature in making the approval of the board retroactive is plain. It was to prevent the penalizing of an employer by the denial to him of his common-law defenses after he had indicated his desire to come under the act, during the short period which must elapse between the filing of his election and its approval by the board.
The judgment must be reversed and a new trial ordered, at which time defendant may interpose the common-law defenses mentioned in section 1 of the act.
