Facts
The facts are rather simple. Sometime in 1983 Security First Life Insurance Company and the law firms of Mitchell, Silber-berg & Knupp and Manatt, Phelps, Rothen-berg & Tunney formed a limited partnership for the purpose of constructing an office building complex on Olympic Boulevard in West Los Angeles. The partnership, Trident Center, the plaintiff herein, sought and obtained financing for the project from defendant, Connecticut General Life Insurance Company. The loan documents provide for a loan of $56,500,000 at 12V4 percent interest for a term of 15 years, secured by a deed of trust on the project. The promissory note provides that “[m]aker shall not have the right to prepay the principal amount hereof in whole or in part” for the first 12 years. Note at 6. In years 13-15, the loan may be prepaid, subject to a sliding prepayment fee. The note also provides that in case of a default during years 1-12, Connecticut General has the option of accelerating the note and adding a 10 percent prepayment fee.
Everything was copacetic for a few years until interest rates began to drop. The I2V4 percent rate that had seemed reasonable in 1983 compared unfavorably with 1987 market rates and Trident started looking for ways of refinancing the loan to take advantage of the lower rates. Connecticut General was unwilling to oblige, insisting that the loan could not be prepaid for the first 12 years of its life, that is, until January 1996.
Trident then brought suit in state court seeking a declaration that it was entitled to prepay the loan now, subject only to a 10 percent prepayment fee. Connecticut General promptly removed to federal court and brought a motion to dismiss, claiming that the loan documents clearly and unambiguously precluded prepayment during the first 12 years. The district court agreed and dismissed Trident’s complaint. The court also “sua aponte, sanctioned] the plaintiff for the filing of a frivolous lawsuit.” Order of Dismissal, No. CV 87-2712 JMI (Kx), at 3 (C.D. Cal. June 8, 1987). Trident appeals both aspects of the district court's ruling.
Discussion
I
Trident makes two arguments as to why the district court’s ruling is wrong. First, it contends that the language of the contract is ambiguous and proffers a construction that it believes supports its position. Second, Trident argues that, under California law, even seemingly unambiguous contracts are subject to modification by parol or extrinsic evidence. Trident faults the district court for denying it the opportunity to present evidence that the contract language did not accurately reflect the parties’ intentions.
A. The Contract
As noted earlier, the promissory note provides that Trident “shall not have the right to prepay the principal amount hereof in whole or in part before January 1996.” Note at 6. It is difficult to imagine language that more clearly or unambiguously expresses the idea that Trident may not unilaterally prepay the loan during its first 12 years. Trident, however, argues that there is an ambiguity because another clause of the note provides that “[i]n the event of a prepayment resulting from a default hereunder or the Deed of Trust prior to January 10, 1996 the prepayment fee will be ten percent (10%).” Note at 6-7. Trident interprets this clause as giving it the option of prepaying the loan if only it is willing to incur the prepayment fee.
We reject Trident’s argument out of hand. In the first place, its proffered interpretation would result in a contradiction between two clauses of the contract; the default clause would swallow up the clause prohibiting Trident from prepaying during the first 12 years of the contract. The normal rule of construction, of course, is that courts must interpret contracts, if possible, so as to avoid internal conflict. See Brobeck, Phleger & Harrison v.
