Tauro, C.J.
These are three bills in equity brought under G. L. c. 214, § 3 (10), to reach and apply an obligation imposed upon the defendant (Lumbermens) by a motor vehicle liability policy issued by Lumbermens to *311one Francis S. Cammarata in satisfaction of judgments obtained by the plaintiffs in actions of tort against Cammarata, G. L. c. 175, §§ 112-113. Lumbermens appeals from final decrees in favor of the plaintiffs in the three bills which were consolidated for trial and appeal. Counsel for Lumbermens withdrew from the case during a trial before an auditor disclaiming liability under the policy on the ground that its insured Cammarata had overstated the coooperation clause in the insurance contract by telling conflicting stories as to the circumstances of the automobile accident.
The trial judge found that “there are minor differences between the signed statement and the transcript concerning background information having no relation to the actual happening of the accident.” The judge considered “these differences are not material, substantial, nor prejudicial in any way.”
The evidence was all documentary, and this court is in the same position as the trial judge to appraise it. See Skil Corp. v. Barnet, 337 Mass. 485, 488; F. A. Bartlett Tree Expert Co. v. Barrington, 353 Mass. 585, 586, n. 1. The guest coverage afforded by the policy was not compulsory and the insurer may, as against the plaintiffs, avail itself of any defences which it would have against the insured. Imperiali v. Pica, 338 Mass. 494, 497-498. See Jertson v. Hartley, 342 Mass. 597, 602. “The intentional furnishing of false information of a material nature either before or at trial is a breach of the cooperation clause.” Cassidy v. Liberty Mut. Ins. Co. 338 Mass. 139, 142. See Williams v. Travelers Ins. Co. 330 Mass. 476, 479, and cases cited therein.
Counsel for Lumbermens at the time of his withdrawal had questioned Cammarata in direct examination only as to the events that occurred earlier in the evening prior to the accident. These events can be considered only to have an indirect bearing on the actual occurrence of the accident. No questions were asked by counsel as to how the accident occurred. “[T]he insurer is not required to show that it was prejudiced by the insured’s *312failure to cooperate, but that . . . does not preclude an inquiry as to whether the breach was not material.” Imperiali v. Pica, supra, at 501. The accident report in question was filed on October 30, 1961 (the accident occurred on September 9, 1961), and the testimony before the auditor was on December 8, 1964, and as this court has stated, “It would not be unusual to find minor discrepancies between a written statement made a few days after an accident and the testimony of a reliable witness under oath given a few years thereafter.” Williams v. Travelers Ins. Co. 330 Mass. 476, 479. The discrepancies between the report and the testimony before the auditor were not of a material nature. They concerned only the details of what Cammarata was doing during the evening prior to the occurrence of the accident. Although a substantial discrepancy existed as to what Cammarata did during the evening of the accident, we agree with the judge below that these differences were not of a material nature and were not shown to have any relationship to the accident itself. Cammarata in his report to the defendant stated he did not drink, except perhaps a beer at supper, but there was testimony before the auditor that he had four bottles of beer during the evening. There was no finding, however, that Cammarata was intoxicated or that his driving ability at the time of the accident was impaired. Nor was there any evidence that the beer contributed in any way to causing the accident. Indeed, counsel for Lumbermens withdrew from the case during his examination of Cammarata without even questioning him as to how the accident happened.
Decrees affirmed with costs of appeal.
