Tanner Motor Tours, Ltd., Tanner Motor Tours of Nevada, Ltd., and Lucky Cab Company appeal from the granting of summary judgment by Judge Bruch-hausen of the United States District Court for the Eastern District of New York in favor of the Flxible Company, third-party defendant appellee. We find no error and affirm the judgment.
The issue presented is the effect of a general release, executed by Tanner and unambiguous on its face, on Tanner’s claim for indemnity by Flxible for liability incurred in a New York action stemming from the same accident in connection with which the release was signed.
The release was a “full and complete release of all or any claims * * * by reason of the happening of said accident * * * including all consequential damage to us [Tanner] on account of injuries to others.” California law, which governs this transaction, holds that extrinsic evidence is not admissible to vary a clear release unless it has been induced through fraud, deception, misrepresentation, overreaching, or misapprehension on the part of the releasor not due to his own neglect but caused by misconduct by the releasee. Moore v. Rogers, 157 Cal.App.2d 192, 320 P.2d 524 (4th Dist.1958); Averett v. Garrigue, 77 Cal.App.2d 170, 174 P.2d 871 (2d Dist.1946). See also Raynale v. Yellow Cab Co., 115 Cal.App. 90, 300 P. 991 (2d Dist.1931); Meyer v. Haas, 126 Cal. 560, 58 P. 1042 (1899); Jordan v. Guerra, 23 Cal.2d 469, 144 P.2d 349 (S.Ct.Cal. en banc 1943.) There was no claim of such improper conduct by Flxible here. Nor is a statutory exception for claims unknown at the time of signing the release relevant, as Tanner does not claim that the Gelfand claim was nonexistent or unknown at that time. Cal.Civil Code 1542; Casey v. Proctor, 59 Cal.2d 97, 28 Cal.Rptr. 307, 378 P.2d 579 (en banc 1963).
The only factor supportive of Tanner’s position is the gross inadequacy of the consideration received for the release in light of the potentially substantial Gelfand judgment. This factor, while it may be considered in connection with other circumstances, has been held “not in itself sufficient to set aside a written release.” Moore v. Rogers, supra, 320 P.2d at 527. Were the federal courts free to fashion the rules in this area, we might consider allowing attack on the release based on this large discrepancy and a claim of mistake. However, under the stricter California law by which we are bound Tanner has no remedy absent factors not shown here.
Judgment affirmed.
