1 1 This is a personal injury action brought by Stephen Peterson against Swire Pacific Holdings Inc. (Swire), a Delaware corporation doing business as Coca-Cola Bottling Company of Salt Lake, for damages sustained in a motor vehicle accident in Salt Lake City. Peterson sued Swire as the employer of the driver, Thomas Stengel (Sten *944 gel), based on the doctrine of respondeat superior. Peterson appeals the trial court's grant of partial summary judgment to Swire.
FACTS
{2 On February 12, 1992, Stengel was driving northbound on 900 East when he fell asleep at the wheel and his car collided with Peterson's. At the time of the accident Stengel was employed by Swire and acting within the scope of his employment.
13 On August 4, 1998, Peterson settled with Stengel for the amount of Stengel's automobile insurance policy limits. Stengel's insurance carrier, Nationwide Mutual Company (Nationwide), paid Peterson $50,000, and in return, Peterson and his wife signed a release. At the time of this settlement, neither Peterson nor his lawyer knew that Stengel was employed by Swire. The relevant part of the release states as follows:
FOR AND IN CONSIDERATION OF the payment to me/us of the sum of $50,000.00 FIFTY THOUSAND & NO/100 Dollars, and other good and valuable consideration, I/we, being of lawful age, have released and discharged, and by these presents do for myself/ourselves, my/our heirs, executors, administrators and assigns, release, acquit and forever discharge Thomas & Susan Stengel and Nationwide Mutual Co. (reserving, however, our rights to, be made whole through our uninsured motorist coverage under our auto insurer, American States Ins. Company ) and any and all other persons, firms and corporations, whether herein named or referred to or not, of and from any and all past, present and future actions, causes of action, claims, demands, damages, costs, loss of services, expenses, compensation, third party actions, suits at law or in equity, including claims or suits for contribution and/or indemnity, of whatever nature, and all consequential damage on account of, or in any way growing out of any and all known and unknown personal injuries, death and/or property damage resulting or to result from an accident that occurred on or about the 18th day of Feb 19 92, at or near 2800 S. & 9th E-SLC Utah.
T4 After settling with Stengel, Peterson obtained $300,000 for his injuries from Peterson's underinsured motorist carrier, American States Insurance (American). Peterson first learned of Stengel's employment with Swire during finalization of negotiations with American. ©
{5 On February 9, 1996, this lawsuit was filed, and on December 8, 1997, Gayle Peterson was appointed Stephen Peterson's conservator and guardian because of his incapacity.
T6 The trial court granted Swire's motion for summary judgment, concluding that: (1) the August 4, 1998 release entered into by Peterson was valid and relieved Swire of lability for all claims involving vicarious liability and respondeat superior; (2) there was no evidentiary or legal basis for reforming, voiding, or otherwise failing to enforce the release entered into by Peterson; and (8) if the release does not release Swire from vicarious liability, then Swire is entitled to a $350,000 credit for the money already received by Peterson from his own underin-sured motorist carrier. 1 Peterson appealed.
STANDARD OF REVIEW
17 Summary judgment is proper only where "there is no genuine issue as to any material fact and ... the moving party is entitled to a judgment as a matter of law." Utah R. Civ P. 56(c). In considering a grant of summary judgment, "we review the court's legal decision for correctness, giving no deference, and review 'the facts and inferences to be drawn therefrom in the light most favorable to the nonmoving party'" Booth v. Attorneys' Title Guaranty Fund, Inc.,
"ANALYSIS
4 8 On appeal, Peterson argues that partial summary judgment should not have been *945 granted. He asserts that (1) the release was not valid to relieve Swire from vicarious liability; (2) the release should have been voided or reformed; and (8) Swire should not have been granted a $350,000 credit toward its liability. ~
I. APPLICABILITY OF THE, RELEASE TO SWIRE
19 Under Utah law, "Releases are contractual provisions and should be interpreted according to well-developed rules of contract interpretation." - Ward - v. Intermountain Farmers Ass'n,
110 In addition to the general rules of contract construction that apply to releases, there are statutory provisions that govern them. The two relevant statutes are section 78-27-42 of the Liability Reform Act (the LRA release clause) and section 15-4-4 of the Joint Obligations Act (the JOA release clause). The LRA release clause provides:
A release given by a person seeking recovery to one or more defendants does not discharge any other defendant unless the release so provides.
Utah Code Ann. § 78-27-42 (1996).
The JOA release clause provides:
[TThe obligee's release or discharge of one or more of several obligors, or of one or more of joint or of joint and several obli-gors, shall not discharge co-obligors against whom the obligee in writing and as part of the same. transaction as the release or discharge expressly reserves his rights; and in the absence of such a reservation of rights shall discharge co-obligors only to the extent provided in Section 15-4-5.
Utah Code Ann. § 15-4-4 (1999).
Both acts similarly provide that "the release of one obligor does not discharge co-obligors against whom the obligee in writing expressly reserves his rights." Nelson v. Corporation of Presiding Bishop of Church of Jesus Christ of Latter-day Saints,
{11 In determining the reach of these two statutes, this court has previously observed that the LRA is a pro tanto repeal of the JOA as it applies to regular co-defendants, but that the JOA still applies to vicariously liable parties. See Nelson,
T 12 We find that the release is unambiguous because it is not "capable of more than one reasonable interpretation." Wine gar,
II. ENFORCEABILITY OF THE RELEASE
{13 Peterson argues that the release is void or should have been reformed because (1) Swire was an undisclosed principal at the time the release was signed and therefore should not be allowed to take advantage of the release; (2) Peterson was incompetent to sign the release; (8) mutual mistake of the parties requires the release's reformation; and (4) applying the JOA instead of the LRA to vicariously liable parties is unconstitutional.
A. Undisclosed Principal
T14 At the time Peterson signed the release agreement with Stengel, he did not know that Stengel was employed by Swire. Peterson argues that because Swire was Stengel's principal, Swire could not be released from vicarious liability for the accident without first disclosing its relationship to Stengel. Swire bases this argument on our decision in Garland v. Fleischmann,
It is well established in the law that a principal is liable for the acts of his agent within the seope of the agent's authority, irrespective of whether the principal is disclosed or undisclosed. The fact that an agent acts in his own name without disclosing his principal does not preclude liability on the part of the principal when he is discovered to be such by a third party who has dealt with the agent. $ Am.Jur2d Agency § 320 (1986). This is true even though the third person dealing with the agent did not learn of the existence of the principal until after the bargain was completed. Holman-O.D. Baker Co. v. Pre-Design, Inc., 104 NH. 116, 118,179 A2d 454 , 455 (1962).
' 15 Peterson's reliance on Garland is misplaced. Garland stands for the proposition that disclosure or nondisclosure of a principal will not absolve the principal of responsibility for an agent's actions. See id. However, the present case does not involve a question of agency or the existence of vicarious lability. Instead, it depends on the interpretation of a contractual release. For purposes of summary judgment, Swire conceded that Stengel was its agent acting in the course of his employment. - Swire does not argue that it is free from liability for its agent's actions based on anything other than the release.
116 Peterson argues that his lack of knowledge of Stengel's agency justifies voiding or reforming the release. " 'If a party's manifestation of assent is induced by either a fraudulent or a material misrepresentation by the other party upon which the recipient is justified in relying, the contract is voidable by the recipient.'" Miller v. Celebration Mining Co.,
B. Competence
117 Peterson argues that the release he signed with Stengel and Stengel's insurer should be voided because of Peterson was incompetent at the time of the contract. Competency to enter a contract is measured by whether "'the mental facilities [were] so deficient or impaired that there was not sufficient power to comprehend the subject of the contract, its nature and its probable consequences, and to act with discretion in relation thereto, or with relation to the ordinary affairs of life'" Walker v. U.S. General Inc.,
118 Peterson offered no evidence before the trial court indicating that he was unable to understand the nature of the release at *947 the time he signed it. He relied on his wife's appointment as his general guardian in 1997 to demonstrate incompetence. The release, however, was signed by Peterson on August 4, 1998, more than four years before the guardianship appointment. Although Mrs. Peterson's appointment as Peterson's general guardian is evidence of incompetence in 1997, it is not evidence that he was incompetent in 1998. Peterson's argument is particularly tenuous in light of the fact that neither Mrs. Peterson, Peterson's lawyer, Stengel, or Stengel's insurance carrier raised any concerns about Peterson's mental capacity at the time the release was signed.
C. Mutual Mistake
119 Peterson next argues that the release should be voided due to mutual mistake. Mutual mistake warrants the reformation of written instruments if the complaining party can show:
(1) that the instrument as made failed to conform to what both parties intended; or (2) that the claiming party was mistaken as to its actual content and the other party, knowing of this mistake, kept silent; or (8) that the claiming party was mistaken as to actual content because of fraudulent affirmative behavior.
Mabey v. Kay Peterson Constr. Co.,
$20 Peterson argues that neither of the parties intended to release Swire; so the release must fail. However, his characterization of the intent of Stengel and his insurance carrier is entirely speculative. Although upon summary judgment the court must view all facts and inferences in favor of the nonmoving party, it may not assume facts for which no evidence is offered. "Allegations or denials in the pleadings are not a sufficient basis for opposing summary judgment." Hall v. Fitzgerald,
D. Constitutionality of the operation of the JOA and the LRA -
121 In general " '[A] constitutional question is not to be reached if the merits of the case in hand may be fairly determined on other than constitutional issues'" State v. Webster,
{22 As mentioned above, in Nelson we held that the release clause of the Joint Obligations Act applies to releases dealing with vicariously liable parties, while the release clause of the Liability Reform Act applies to all other co-defendants. See Nelson,
1283 Article I, Section 24 provides that: "All laws of a general nature shall have uniform operation." Utah Const. art. I, § 24. Under the uniform operation of laws clause, we utilize a lower standard of review unless the statute infringes a "fundamental or critical right ... [or creates] classifications considered impermissible or suspect in the abstract." Ryan v. Gold Cross Services, Inc.,
$24 The first question is whether there is anything inherently unreasonable in the legislature's decision to treat vicariously liable defendants differently than other co-defendants. See Ryan,
125 The second issue is whether the legislative purpose in separating vicariously liable defendants from regular co-defendants is legitimate. "[The court will sustain legislative action if it can reasonably conceive of facts which would justify. the classifications made by the legislation." Ryan,
126 The LRA was intended "only to abolish the joint and several liability of 'defendants' ... but that does not affect an employer, who being only vicariously liable is not a 'defendant.'
2
Nelson,
127 The last issue is whether there is a reasonable relationship between the statutory classification and the legislative purpose. We conclude that the classification is not an unreasonable means of achieving fairness in the apportionment of damages between different kinds of defendant.
3
Even though the legislative distinction between at-fault co-defendants and vicariously liable co-defendants requires two separate standards for the creation and interpretation of releases, it is not the court's place "to defend the merits,
*949
desirability, or rationality of legislative action." Eyan,
128 Peterson extends his uniform operation of laws argument to plaintiffs who are disparately affected in their ability to collect damages by virtue of different standards governing releases under the JOA and the LRA. We disagree with the argument that the disparity is unconstitutional. In reality, both the JOA and the LRA provide a plaintiff with equal opportunity to pursue all liable parties. Neither the JOA nor the LRA will release either an at fault co-defendant or a vicariously liable one where the release expressly reserves the plaintiff's rights to pursue those parties. See Nelson,
III THE EXTENT OF SWIRE'S LIABILITY
129 In view of our holding regarding the applicability of the JOA to this release and its. constitutionality, we affirm the trial court's dismissal of Swire by summary judgment. The issue of credit for underinsured motorist payments is thus moot.
CONCLUSION
1 80 We affirm the district court's grant of summary judgment regarding the validity of the release signed by Peterson, as well as the lack of evidentiary or legal basis to void or reform it. We vacate the district court's grant of summary judgment regarding the extent of Swire's lability as the issue is moot.
Notes
. The district court also found that punitive damages were not permissible in this case. This ruling has not been challenged.
. Section 78-27-37 of the LRA states: "(1) 'Defendant' means a person, other than a person immune from suit ..., who is claimed to be liable because of fault to any person seeking recovery. (2) 'Fault' means any actionable breach of legal duty, act, or omission proximately causing or contributing to injury or damages sustained by a person seeking recovery, including negligence in all its degrees, contributory negligence, assumption of risk, strict liability, breach of express or implied warranty of a product, products liability, and misuse, modification or abuse of a product."
. Other state legislatures have made an explicit distinction between vicariously liable defendants and regular co-defendants when abrogating joint and several liability. See Ariz.Rev.Stat. Ann. § 12-2506(D)(2001); Idaho Code § 6-803(5) (2000); Wash. Rev.Code Ann. § 4.22.070(1)(a) (2002).
