MEMORANDUM **

Plaintiff Dietz International Public Adjusters of California, Inc. appeals the district court’s grant of summary judgment to defendant Evanston Insurance Co. in Dietz’s diversity action seeking reimbursement of payments made to settle claims against it. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Hansen v. Dep’t of Treasury, 528 F.3d 597, 600 (9th Cir. 2007), and we affirm.

The statutory language of Section 554 of the California Insurance Code is unambiguous and does not preclude Evanston from enforcing a provision in Dietz’s professional liability insurance policy that bars Dietz from making voluntary payments to settle claims against it. See Insua v. Scottsdale Ins. Co., 104 Cal.App.4th 737, 743, 129 Cal.Rptr.2d 138 (2002), review denied, No. S112788 (Feb 25, 2003) (holding that insurer could assert voluntary payments defense even when it failed to promptly assert a late notice defense).

*681 On its face, Section 554 provides only for the waiver of an insurer’s late notice defense, a substantively different defense than the voluntary payments defense that Evanston asserted at summary judgment. See id. Because Dietz failed to demonstrate that Evanston intentionally relinquished its right to raise its voluntary payments defense, Evanston has not waived that defense under California law. See Waller v. Truck Ins. Exch., Inc., 11 Cal.4th 1, 31, 44 Cal.Rptr.2d 370, 900 P.2d 619 (1995).

AFFIRMED.
