institution and precludes or prohibits review in a court of law. This is what was done by Lafayette College in Baker and, allegedly, by the University in this case. When a contract so specifies, generally applicable principles of contract law will suffice to insulate the institution’s internal, private decisions from judicial review.
We, therefore, agree with Murphy on the threshold issue and hold that the governing standard of review is that which the Pennsylvania courts have traditionally applied in determining whether summary judgment was properly granted in a breach of contract case.
Our review on an appeal from the grant of a motion for summary judgment is well-settled. A reviewing court may disturb the order of the trial court only where it is established that the court committed an error of law or abused its discretion. Capek v. Devito, 767 A.2d 1047, 1048, n. 1 (Pa.2001). As with all questions of law, our review is plenary. Phillips v. A-Best Products Co., 542 Pa. 124, 665 A.2d 1167, 1170 (1995).
In evaluating the trial court’s decision to enter summary judgment, we focus on the legal standard articulated in the summary judgment rule. Pa.R.C.P. 1035.2. The rule states that where there is no genuine issue of material fact and the moving party is entitled to relief as a matter of law, summary judgment may be entered. Where the non-moving party bears the burden of proof on an issue, he may not merely rely on his pleadings or answers in order to survive summary judgment. “Failure of a non-moving party to adduce sufficient evidence on an issue essential to his case and on which it bears the burden of proof .... establishes the entitlement of the moving party to judgment as a matter of law.” Young v. Penn-DOT, 560 Pa. 373, 744 A.2d 1276, 1277 (2000). Lastly, we will view the record in the light most favorable to the non-moving party, and all doubts as to the existence of a genuine issue of material fact must be resolved against the moving party. Pennsylvania State University v. County of Centre, 532 Pa. 142, 615 A.2d 303, 304 (1992).
In order to evaluate Murphy’s contention that summary judgment in the University’s favor is precluded by the existence of genuinely disputed, material facts as to whether the University breached the Contract when it determined that Murphy had forfeited his tenure, we must determine the Contract’s terms. The principles of law that control this determination are well-established.
The fundamental rule in interpreting the meaning of a contract is .to ascertain and give effect to the intent of the contracting parties. Felte v. White, 451 Pa. 137, 302 A.2d 347, 351 (1973). The intent of the parties to a written agreement is to be regarded as being embodied in the writing itself. Steuart v. McChesney, 498 Pa. 45, 444 A.2d 659, 661 (1982). The whole instrument must be taken together in arriving at contractual intent. Felte, 302 A.2d at 351. Courts do not assume that a contract’s language was chosen carelessly, nor do they assume that the parties were ignorant of the meaning of the language they employed. Steuart, 444 A.2d at 662. “ When a writing is clear and unequivocal, its meaning must be determined by its contents alone.’ ” Felte, 302 A2d at 351 (quoting East Crossroads Center Inc. v. Mellon Stuart Co., 416 Pa. 229, 205 A.2d 865, 866 (1965)).
Only where a contract’s language is ambiguous may extrinsic or parol evidence be considered to determine the intent of the parties. Hutchison v. Sunbeam Coal Co., 513 Pa. 192, 519 A.2d 385,
