OPINION
This action requires that we answer two related questions. First, we must determine whether the brokerage contract between the American Bureau of Shipping (ABS) and McDade + Company is ambiguous. Second, if we conclude that the contract is not ambiguous, we must determine whether its terms permit ABS to lease office space from Friendswood Development Company without breaching the contract or subjecting Friends-wood to liability for tortiously interfering with the contract. We conclude that the contract is not ambiguous and that its express terms permit ABS to lease office space from Friendswood without subjecting either to liability to McDade. Accordingly, the Court, without hearing oral argument, reverses in part and affirms in part the court of appeals’ judgment. Tex.R.App.P. 170.
ABS, a New Jersey corporation, desired to relocate to Houston, Texas. ABS’s president, formerly the president of Exxon Shipping, contacted Friendswood Development Company, an Exxon affiliate, to arrange for office space in one of its Greenspoint office buildings. Friendswood informed ABS that it had no available space, but that one of its Greenspoint I tenants would be moving to the new Greenspoint V building in about a year and at that time ABS could move to the vacated space in Greenspoint I. Friends-wood also proposed that it would lease space in the Belchase Building, a property Friends-wood did not own, and then sublet it to ABS for the year. Under this proposal, Belchase would serve as ABS’s interim office.
While considering the Friendswood proposal, ABS contacted McDade + Company, a real estate brokerage firm. ABS hired McDade to evaluate alternative leasing arrangements. McDade presented its standard exclusive brokerage contract to ABS that provided McDade was the sole broker and had the exclusive right to obtain a lease or purchase of premises on ABS’s behalf. ABS informed McDade of its ongoing discussions with Friendswood and its desire to exclude Friendswood and other Exxon affiliates from the brokerage contract. Accordingly, McDade inserted an exception in the standard brokerage contract that excluded Friendswood from the contract, thus permitting ABS to contract with either McDade or Friendswood for office space. After McDade inserted the provision excluding Friendswood and all other Exxon affiliates from the terms of the brokerage contract, ABS signed the contract. Thereafter, ABS accepted the Friendswood proposal of interim leasing for the year until space in Greenspoint I became available. After the year, ABS would begin a long-term lease at Greenspoint I.
When McDade discovered that Friends-wood had leased space to ABS that it did not own, McDade filed the present suit alleging that ABS breached the brokerage contract and that Friendswood tortiously interfered with the brokerage contract. Both Friends-wood and ABS filed motions for summary judgment, which the trial court granted. The court of appeals affirmed the summary
*282
judgment for ABS, but reversed the summary judgment for Friendswood, holding that the brokerage contract was ambiguous and that Friendswood could not rely on the justification defense to a tortious interference claim.
Because this is an appeal from a summary judgment, we take as true evidence favorable to the non-movant.
Nixon v. Mr. Property Management Co.,
A tortious interference cause of action is established if the plaintiff proves: (1) the existence of a contract subject to interference; (2) a willful and intentional act of interference; (3) the act was a proximate cause of the plaintiffs damages; and (4) actual damage or loss resulted.
Texas Beef Cattle Co. v. Green,
The question we must-first decide is whether the McDade/ABS brokerage contract is ambiguous. Whether a contract is ambiguous is a question of law for the court to decide.
National Union Fire Ins. v. CBI Indus., Inc.,
An ambiguity in a contract may be either patent or latent. A patent ambiguity is one evident on the face of the contract.
National Union,
We hereby appoint McDade + Company (“McDade”) as our sole broker and grant to McDade the exclusive right to obtain a lease or purchase of Premises on our behalf, with the exception of Friendswood Development Company or other Exxon affiliates which are excluded from the terms of this contract.
From the express language of the contract it is apparent that ABS appointed McDade as its exclusive broker, but that it excluded Friendswood from the contract’s terms. There is no limitation of any kind on the exclusion. Therefore, Friendswood and all other Exxon affiliates are excluded from the terms of the contract. Because, on its face, the meaning of the exclusion is clear, no patent ambiguity exists.
McDade, however, asserts that the contract contains a latent ambiguity. A latent ambiguity exists when a contract is unambiguous on its face, but fails by reason of some collateral matter when it is applied
*283
to the subject matter with which it deals.
National Union,
[I]f a contract called for goods to be delivered to “the green house on Pecan Street,” and there were in fact two green houses on the street, it would be latently ambiguous.
National Union,
Because the contract does not contain either patent or latent ambiguities, we give the contract its plain grammatical meaning.
Lyons v. Montgomery,
We next address McDade’s claims against ABS. McDade asserts that ABS breached the McDade/ABS contract by leasing space from Friendswood. McDade also contends that ABS tortiously interfered with the contract, breached other tort duties, and deprived McDade of its commission. Because we hold that the brokerage contract is not ambiguous and allows ABS to contract with Friendswood, we also hold that ABS conclusively proved that it did not breach the contract or breach any tort duties simply by proceeding in accordance with the terms of the contract. Moreover, MeDade’s argument that ABS tortiously interfered with the contract is specious. A party to a contract cannot tortiously interfere with its own contract.
Holloway,
We hold that both Friendswood and ABS were entitled to summary judgment. Pursuant to Rule 170 of the Texas Rules of Appellate Procedure, the Court, without hearing oral argument, reverses that part of the court of appeals’ judgment reversing summary judgment for Friendswood and renders judgment that McDade take nothing. We affirm the remainder of the court of appeals’ judgment. Tex.R.App.P. 170.
Notes
. As we held in National Union:
Extrinsic evidence may, indeed, be admissible to give the words of a contract a meaning consistent with that to which they are reasonably susceptible, i.e., to "interpret” contractual terms. If the contract language is not fairly susceptible of more than one legal meaning or construction, however, extrinsic evidence is inadmissible to contradict or vaty the meaning of the explicit language of the parties' written agreement.
