138 N.W.2d 501
DOUTRE
v.
NIEC.
Docket No. 402.
Michigan Court of Appeals.
Decided December 20, 1965.
Rehearing denied January 26, 1966.
*89 Howard C. Fisher, for plaintiff.
Walter J. Barkey, for defendants.
T.G. KAVANAGH, J.
Defendants operate a beauty shop in Flint. On April 19, 1962, plaintiff was given a bleach and color treatment by defendants without a pretreatment patch test. Plaintiff received head and facial injuries as a result of the treatment and sued for damages.
During the trial defendants were not allowed to testify as to the standard of care observed by beauty shops in the Flint area when administering such treatment. The jury awarded plaintiff $10,000. Defendants filed a motion for a new trial. Such motion was granted and a new trial ordered but limited to the question of liability.
Both parties appeal.
The plaintiff alleges error in granting the new trial as to liability on the theory that the court was correct in the first place when he ruled at the trial that the proffered testimony on the standard of care was not admissible. The defendants allege the court erred in limiting the new trial to the issue of liability on the theory that the questions of liability and damages are so closely intertwined that they should be tried together.
As to the plaintiff's claim we find little merit. His objection is based on the theory that the defendants *90 could know of the practices of the trade in Flint only by hearsay. This is not supported by the record.
The record shows that one of the defendants had been in the business for 24 years and the other for 14 years; they had attended conventions of beauticians and observed their practices and said they were abreast of the practices of other beauticians in Genesee county.
We agree with the trial court's last ruling that these witnesses should have been allowed to testify and that to exclude their testimony was error requiring a new trial. Such testimony is admissible because no one is held to a higher standard of care than the average in the industry. Barton v. Myers (1965), 1 Mich App 460.
The limitation of the trial to the issue of liability only poses a more difficult problem. It has long been recognized that the questions of liability and damages are so closely intertwined that they may not usually be separated. The only exception the Michigan Supreme Court has so far recognized is in the case wherein "liability is clear" a retrial of the issue of damage alone may be permitted. Trapp v. King (1965), 374 Mich 608.
In this case the court reiterated its position that despite the court rule authorizing it (GCR 1963, 527.1), limited new trials are not favored. No compelling reason moves us to extend the rule.
The trial judge's opinion states: "This ruling (on the evidentiary question) may have materially influenced the jury on the liability issue. It could not, however, by any stretch of the imagination have affected the issue of damages." This bespeaks an assurance we do not share.
In the case before us the damages are not liquidated and the liability was determined pursuant to a trial in which an admitted error touching on liability was committed. Under these circumstances *91 it seems to us that justice requires that the jury which determines the liability or lack of it should have the responsibility for measuring any damages.
The trial court's order for a new trial shall be extended to all of the issues. Costs are awarded defendants.
McGREGOR, P.J., and FITZGERALD, J., concurred.
