SMITH
v.
MICHIGAN STATE ACCIDENT FUND
Docket No. 59718.
Supreme Court of Michigan.
Decided July 24, 1978.
The Cox Law Firm, P.C. for plaintiffs.
Vandeveer, Garzia, Tonkin, Kerr & Heaphy, P.C. (by James A. Sullivan), for defendant Michigan State Accident Fund.
PER CURIAM:
The question is whether the trial court's decision that the Michigan State Accident Fund was estopped from denying coverage to appellant has record support.
Robert Smith's service station business was insured for workers' compensation by the State Accident Fund (SAF). Smith contacted a licensed insurance agent named Robb to arrange procurement of workmen's compensation insurance for another business  an automobile dealership. Robb submitted an application which was received by the SAF on August 4, 1967. Correspondence took place between Robb and an employee of SAF concerning information about the application. The employee for the SAF which handled the policy application went on vacation on August 11, 1967 and returned to work on August 21, 1967. The policy was not processed until August 22 because the employee had failed to follow the normal procedure of assigning the application to another employee. The SAF struck the desired effective date of August 4 on Smith's application and replaced it with August 22.
Smith thought he had coverage and on August 15 prepared to open the dealership. On August 18, an employee died due to a work-related accident.
*203 Smith brought suit against the SAF and Robb[1] to recover workmen's compensation benefits paid to the deceased employee and on March 25, 1975 the trial court issued an opinion favorable to Smith. The gist of the trial court's 16-page opinion is as follows:
"For the above reasons, and the other reasons stated in this opinion, this court concludes, and finds as a fact, that defendant, Michigan State Accident Fund, was negligent in the processing, in fact it failed to process plaintiffs' application for additional insurance covering the Ford dealership until after the death of Allen Elliott; that all questions asked by defendant Fund's underwriter, Mr. Paul Wilcox, had been answered at the time of Elliott's death; that defendant Fund would have issued the additional requested insurance policy in the ordinary course of business; that it would have issued the additional requested coverage had it not been for the death of Elliott; that defendant's underwriter, Mr. Paul Wilcox, had no right to alter the original application for additional insurance coverage, the Fund accept and retain the additional premiums and then deny coverage and liability to plaintiffs as employer of Elliott, and therefore, as a matter of fact and as a matter of law is estopped to deny coverage, and this court holds that at the time of Allen Elliott's death Bob Smith Ford, Inc., was insured by the defendant, Michigan State Accident Fund."
The majority of the Court of Appeals concluded that the trial court's determination was clearly erroneous. Judge BEASLEY dissented on the ground that there were sufficient facts in the record on which the trial court could base its decision. 73 Mich App 710; 252 NW2d 556 (1977).
An appellate court must give due deference to *204 the findings of a trial court.[2] In Tuttle v Dep't of State Highways, 397 Mich 44, 46; 243 NW2d 244 (1976), we said:
"Under GCR 1963, 517.1, an appellate court will set aside the findings of fact of a trial court sitting without a jury when such findings are clearly erroneous. In construing comparable `clearly erroneous' language in Rule 52(a) of the Federal Rules of Civil Procedure, the United States Supreme Court has stated that `[a] finding is "clearly erroneous" when although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been committed.' [United States v United States Gypsum Co, 333 US 364, 395; 68 S Ct 525, 542; 92 L Ed 746, 766 (1948)]."
We conclude that the decision of the trial court that SAF's negligence precluded it from denying coverage contains record support[3] and is not *205 clearly erroneous under the standard set forth in Tuttle.
In lieu of granting leave to appeal, pursuant to GCR 1963, 853.2(4), we reverse the judgment of the Court of Appeals and reinstate the trial court judgment.
KAVANAGH, C.J., and WILLIAMS, LEVIN, COLEMAN, FITZGERALD, RYAN, and BLAIR MOODY, JR., JJ., concurred.
NOTES
[1]  A judgment of no cause of action entered as to Robb; that judgment has not been appealed.
[2]  GCR 1963, 517.1 provides in part that "regard shall be given to the special opportunity of the trial court to judge the credibility of those witnesses who appeared before it".
[3]  The application submitted by plaintiff contained a question as to the date the applicant desired coverage to commence with which plaintiff answered, August 4, 1976. The chief underwriter, Harry Tracy, testified that when an underwriter receives an application for insurance where an immediate coverage date is requested, this indicates to the underwriter a need for the SAF to take prompt action. SAF employee Wilcox was assigned the application. He sent a request for more information and Robb promptly responded. Another request for further information believed by Robb to be unnecessary came from Wilcox. Robb answered questions and personally visited the SAF office. Underwriter Wilcox had gone on vacation without assigning the case to another underwriter. Chief underwriter Tracy testified that when an underwriter is absent, the general procedure is for the work to be handled by the remaining underwriters. SAF underwriter Wixom decided not to get into the matter until Wilcox returned, notwithstanding the personal visits of Robb. Robb had obtained prior coverage for Smith without problems. Robb testified that such coverage was not difficult to get. Plaintiff had coverage for his gas station with SAF. Mr. Tracy testified that while normally the Fund did not issue a policy on the same day of the application, policies were issued on the same day of the application when "we've previously issued policies to the same applicant". Plaintiff testified that he recalled never being informed that he had no coverage by SAF or Robb. Plaintiff testified that he received a notice from SAF on or about August 12 or 15, 1967 (before the employee's death) which informed him that he was covered.
