Roger and Carol Knott, along with Bascom Management, Inc. (a corporation owned and controlled by the Knotts), appeal the district court’s summary judgment in favor of McDonald’s Corporation in the Knotts’ diversity action for breach of contract, breach of the implied covenant of good faith and fair dealing, and tortious interference with contractual relations.
The district court had jurisdiction under 28 U.S.C. § 1332, and we have jurisdiction under 28 U.S.C. §§• 1291 & 1332. We affirm.
I
The Knotts operated two McDonald’s restaurants in the San Jose area — the Bascom Avenue and Camden Way McDonald’s — pursuant to franchise agreements with McDonald’s. Around August 1995, the Knotts decided to sell their franchises. Jason and Julie Cartie, who owned and operated a McDonald’s franchise in upstate New York, expressed an interest in buying the franchises. The Knotts and Carties entered into an agreement that provided that the Carties would purchase the franchises for $3.5 million but also granted the Carties an absolute right to withdraw from the contract. After the Carties flew to San Jose to meet with the Knotts, tour the McDonald’s restaurants, and meet with McDonald’s representatives, the Knotts and Carties abandoned the proposed sale. The Knotts eventually sold their franchises, and assigned “all [their] right, title and interest” in the franchises, to Dania and Cosme Fagundo for $2.85 million.
After the sale, the Knotts filed suit against McDonald’s asserting two claims for relief, the first for breach of contract and breach of the implied covenant of good faith and fair dealing, and the second for tortious interference with contractual relations. The Knotts alleged that certain statements and disclosures that McDonald’s representatives made to the Carties violated the franchise agree-
II
The Knotts first claimed that McDonald’s materially breached its franchise agreements and the implied covenant of good faith and fair dealing through it's “discriminatory, arbitrary, unreasonable and unfair interference” with the prospective sale of the Knotts’ franchises to the Carties. The district court ruled that, under Illinois law,
The Knotts do not contest that rights attached to. a contract, including the right to sue for breach of contract, are assignable. Rather, the Knotts contend that their assignment of rights to the Fagundos did not include the right to sue for breach of contract because they never intended to assign that right. The Knotts’ focus on intent is proper to a point. “The undisputed Illinois rule of law is that whether an assignment of contract rights has occurred is a function of the intent of the parties.”’ McHenry Hosp. v. Metropolitan Life Ins. Co.,
Notwithstanding broad language in Young v. Chicago Fed. Sav. & Loan Ass’n,
Whether or not a contract is ambiguous is a question of law. See National Tea Co. v. American Nat’l Bank and Trust Co. of Chicago,
Because the clear and unambiguous language of the Knotts’ assignment evinces an intent to transfer to the Fagundos “all” rights under the franchise agreements, we affirm the district court’s summary judgment on the first claim for relief.
III
The district court also entered summary judgment for McDonald’s on the Knotts’ second claim for relief, for “Tortious Interference with Contractual Relations.” The district court ruled that, under California law,
The existence of a valid contract between plaintiff and a third party is an essential element of a claim of tortious interference with contractual relations. See Pacific Gas & Elec. Co. v. Bear Stearns & Co.,
Because the Knotts could not establish an essential element of their tortious interference claim, we affirm the^_ district court’s summary judgment on the second claim for relief.
Finally, we hold that the district court did not abuse its discretion in denying the Knotts’ Rule 56(f) motion. None of the evidence sought by the Knotts could have changed the clear and unambiguous language of them assignment or rendered enforceable their contract with the Carties. Accordingly, none of the evidence sought could have forestalled summary judgment.
AFFIRMED.
Notes
. The district court amended its original unpublished order granting summary judgment to allow for its publication. For this reason, we deem our opinion appropriate for publication as well. See 9th Cir. R. 36-2(e).
. Because we affirm these rulings, we need not consider the district court's alternative ruling that the Knotts failed to establish a genuine issue of material fact as to whether McDonald's alleged interference dissuaded the Carties from purchasing the Knotts' franchises.
. The parties do not dispute that, pursuant to a choice of law provision in the franchise agreements, Illinois law governs the interpretation of the franchise agreements and assignment of rights thereunder.
. Although Martino v. McDonald's Sys., Inc.,
. The Knotts waived their argument that the assignment is unconscionable if read to include the right to sue for breach of contract. See, e.g., Arizona v. Components Inc.,
. The parties do not dispute that California law governs the Knotts' tortious interference claim.
. The district court did not err by failing to construe the Knotts' claim of tortious interference with contractual relations as a claim of tortious interference with prospective economic advantage. The Knotts pled only the former tort, and the California Supreme Court has warned against blurring the line between these distinct claims. Della Penna v. Toyota Motor Sales,
