ON MOTION FOR REHEARING
CARROLL, Chief Justice.
The opinion and judgment of the Court in this cause handed down on January 13, 1993, are withdrawn and the following opinion substituted therefor.
Kawasaki Motors Corp. U.S.A. ("Kawasaki") appeals from the judgment of the district court affirming a final order of the Texas Motor Vehicle Commission ("the Commission"). We will reverse the district court's judgment and will render judgment remanding this proceeding to the Commission for further proceedings consistent with this opinion.

BACKGROUND
This dispute arises out of a franchise relationship between Kawasaki and D.K.D. Investments, d/b/a Humble Kawasaki ("D.K.D."). In 1986, D.K.D. purchased an existing Kawasaki motorcycle dealership in Humble, Texas and entered into a franchise agreement with Kawasaki. The franchise agreement included a floorplan-financing agreement and granted Kawasaki a security interest in the financed vehicles. By separate agreement, D.K.D. leased a computer system and software package from Kawasaki. This system was specifically designed for placing merchandise and parts orders with Kawasaki. Almost immediately, the parties quarrelled over the inclusion of older model vehicles in the initial inventory and the hourly rate for warranty work. Later, other disagreements developed concerning unauthorized "drop-shipments" of motorcycles and multiple-unit inventory purchasing requirements.
D.K.D. soon developed financial troubles. By late summer of 1987, D.K.D. had defaulted on its floorplan financing, had failed to make payments for vehicles sold, and had given Kawasaki several "hot" checks. On August 26, 1987, representatives of Kawasaki appeared at D.K.D.'s place of business and effected a self-help repossession of the motorcycle inventory. Kawasaki's representatives also removed the leased computer system and the dealership files. Kawasaki canceled D.K.D.'s unfilled parts orders, and Kawasaki's representatives allegedly instructed D.K.D. that it could no longer submit orders or warranty work claims to Kawasaki.
D.K.D. initiated the underlying action with the Texas Motor Vehicle Commission as an administrative-complaint proceeding. D.K.D. complained that the actions taken by Kawasaki constituted a wrongful termination *794 of D.K.D.'s franchise under section 5.02(3) of the Texas Motor Vehicle Commission Code ("the Code").[1] Act of May 20, 1987, 70th Leg., R.S., ch. 357, sec. 24, § 5.02(3), 1987 Tex.Gen.Laws 1781, 1789 (Tex.Rev.Civ.Stat.Ann. art. 4413(36), § 5.02(3), since amended). D.K.D. also complained that (1) Kawasaki had failed to repurchase vehicles, parts, and advertising signs upon termination as required under section 5.02(14);[2] (2) Kawasaki had required D.K.D. to accept delivery of unordered vehicles in violation of section 5.02(1);[3] (3) Kawasaki had failed to deliver reasonable quantities of motorcycle inventories in violation of section 5.02(2);[4] and (4) Kawasaki had failed to fully compensate D.K.D. for warranty work in violation of section 5.02(9).[5]
After a two-day hearing, the hearings examiner found that Kawasaki had violated the Code and recommended that civil penalties and damages be awarded. The Commission adopted the findings and conclusions of the hearings examiner and issued a final order against Kawasaki for (1) $22,000.00 in civil penalties for violations of the Code; (2) $684.64 in damages to D.K.D. for warranty work performed but not compensated; (3) $51,895.71 in damages to D.K.D. for claims under section 5.02(14); and (4) the cost of the transcript of the hearing.
After exhausting its administrative remedies, Kawasaki brought this action for judicial review under section 19 of the Administrative Procedure and Texas Register Act, Tex.Rev.Civ.Stat.Ann. art. 6252-13a (West Supp.1992) ("APTRA"), by filing its original petition in the district court of Travis County. The district court upheld the order of the Commission, and Kawasaki appeals the district court's judgment.

DISCUSSION AND HOLDING

Inventory, Shipment and Warranty Work Complaints
Kawasaki's third and fourth points of error turn on the same standards of review; therefore, we will discuss them together. The Commission found that Kawasaki required D.K.D. to accept undesired merchandise as its initial inventory, required D.K.D. to accept undesirable merchandise to obtain the more popular vehicles, and delivered unordered vehicles to D.K.D. Kawasaki challenges the Commission's resulting conclusions that Kawasaki violated sections 5.02(1) and (2) and the associated assessment of civil penalties as arbitrary and capricious and not supported by substantial evidence.
Kawasaki also challenges the Commission's finding that Kawasaki failed to pay for warranty work as required by section 5.02(9) and the Commission's related assessment of civil penalties as not supported by substantial evidence and as an unwarranted exercise of discretion.
To determine whether an agency's action is arbitrary and capricious, we generally need only determine whether its actions are supported by substantial evidence, for an agency's actions are generally considered arbitrary and capricious under APTRA § 19(e)(6) if they are not supported by substantial evidence. Texas Health Facilities Comm'n v. Charter Medical-Dallas, Inc., 665 S.W.2d 446, 454 (Tex.1984).
This Court extensively discussed the substantial evidence test in Lone Star Salt Water Disposal Co. v. Railroad Commission of Texas:
*795 To determine whether an agency's decision is supported by substantial evidence, as APTRA § 19(e)(5) requires, we must determine whether, in considering the record upon which the decision is based, the evidence as a whole is such that reasonable minds could have reached the conclusion which the Commission must have reached in order to justify its action. In determining whether there is substantial evidence to support the order, the reviewing court may not substitute its judgment for the Commission's, and must consider only the record upon which the decision is based. The evidence in the agency record may actually preponderate against the Commission's decision, but still amount to substantial evidence supporting it. The burden is on the complaining party to demonstrate an absence of substantial evidence.
Final orders of the Commission are presumed to be valid. Where the evidence in the record before an agency will support either an affirmative or a negative finding, the agency order must be upheld. Any conflict in the evidence must be resolved in favor of the agency's decision.
Lone Star Salt Water Disposal Co. v. Railroad Comm'n, 800 S.W.2d 924, 928 (Tex.App.Austin 1990, no writ) (citations omitted).
In some instances, an agency decision which is supported by substantial evidence is nonetheless arbitrary and capricious. To determine whether an agency action is the type of arbitrary conduct that violates APTRA, even though supported by substantial evidence, we must ascertain whether (1) the agency denied a litigant due process, Lewis v. Metropolitan Sav. & Loan Ass'n, 550 S.W.2d 11, 16 (Tex.1977); (2) the agency completely failed to make findings of fact and instead based its decision on findings in another case, Railroad Comm'n v. Alamo Express, 308 S.W.2d 843, 846 (Tex.1958); (3) the agency improperly based its decision on non-statutory criteria, Public Util. Comm'n v. South Plains Elec. Coop., Inc., 635 S.W.2d 954, 957 (Tex.App.Austin 1982, writ ref'd n.r.e.); or (4) the agency abused its discretion by basing its decision on legally irrelevant factors, or by failing to consider legally relevant factors. Consumers Water, Inc. v. Public Util. Comm'n, 774 S.W.2d 719, 721 (Tex.App.Austin 1989, no writ); Starr County v. Starr Indus. Servs., Inc., 584 S.W.2d 352, 355-56 (Tex.Civ.App. Austin 1979, writ ref'd n.r.e.).
Another court of appeals has suggested an additional hurdle for demonstrating a violation of the arbitrary and capricious standardfor a finding, which is supported by substantial evidence, to be arbitrary and capricious, it must be based on a violation of due process or some other unfair or unreasonable conduct that shocks the conscience. Texas State Bd. of Dental Examiners v. Silagi, 766 S.W.2d 280, 285 (Tex. App.El Paso 1989, writ denied).
Upon examination of the record, we conclude that substantial evidence exists to support the Commission's findings. While the record contains conflicting evidence concerning the violations of sections 5.02(1), (2) and (9), reasonable minds could have reached the conclusion that the Commission reached and we will not substitute our judgment for that of the Commission. Additionally, we conclude that the Commission's findings were not arbitrary and capricious. We overrule Kawasaki's third and fourth points of error.

Termination Without Statutory Notice
In its first point of error, Kawasaki challenges the Commission's finding that Kawasaki terminated D.K.D.'s franchise without 60-days written notice, as section 5.02(3) requires. To support this argument Kawasaki urges two theoriesthat the Commission exceeded its statutory and constitutional authority and that the Commission misconstrued the Code.
Under its first argument, Kawasaki contends that it was merely exercising its rights as a secured creditor, that its actions did not terminate D.K.D.'s franchise, and that its actions were proper under article 9 of the Uniform Commercial Code, Tex.Bus. & Com.Code Ann. §§ 9.101-.507 (West *796 1991). Kawasaki contends that the Commission's order limits the valid exercise of its right as a secured creditor to protect its interests, and, therefore, was outside the Commission's statutory authority. Kawasaki interprets the Commission's decision to imply that a franchisor-secured creditor could not repossess collateral without first giving the franchisee-debtor 60-days written notice. Such a requirement, Kawasaki argues, would impair the creditor's contractual security interest and, thus, would violate the creditor's substantive and procedural due-process rights and the constitutional prohibition of impairment of contracts. See Tex. Const. art. I, § 16.
We decline to interpret the Commission's order or its implications so broadly. We conclude that the Commission based its finding of de facto termination not merely on Kawasaki's repossession of the motorcycles, but on the totality of Kawasaki's actions. The hearings examiner stated in his proposal for decision "that an effective termination took place on August 26, 1987 when Kawasaki repossessed the Complainant's inventory of motorcycles, computer terminal, and records" and that "the facts presented in this case show more than just a repossession having occurred and it is these additional elements that make up a finding of wrongful termination." The hearings examiner expressly limited his proposal to "not ... imply that a creditor may not repossess secured property when circumstances warrant." Kawasaki undertook more than a self-help repossession; it seized D.K.D.'s dealership files, it repossessed the leased computer although the record reflected no default under the lease agreement, it canceled unfilled parts orders, and it instructed D.K.D. not to place orders or submit warranty-work claims. We conclude that the Commission's order did not exceed its statutory authority or conflict with Kawasaki's rights as a secured creditor.
In its second argument, Kawasaki contends that the Commission failed to recognize that Kawasaki had not terminated D.K.D.'s right to sell Kawasaki products at the time of the repossession, and therefore, misconstrued the Code. Kawasaki refers to the definition of "franchise" in section 1.03(8), which describes a franchise, in part, as a contractual right to sell a product.[6] Kawasaki argues that since D.K.D. retained the right to sell Kawasaki products after the repossession and since no "contracts" were terminated, the franchise, as defined by the Code, still existed. We disagree. As stated above, the Commission found that there was a de facto termination of the franchise. This finding was based on the totality of Kawasaki's actions and did not depend on a formal cancellation of D.K.D.'s intangible right to sell Kawasaki products or the termination of a contract.
Kawasaki also argues that this finding was not supported by substantial evidence. Kawasaki concedes that, in addition to repossession of the motorcycles, it seized the computer system and the dealership files and canceled all unfilled parts orders. While there is conflicting evidence on the representations Kawasaki's agents made concerning D.K.D.'s right to order on cash and to submit warranty-work claims, we will not substitute our judgment on the weight to be given the evidence for that of the Commission. Based upon the above-stated standards, we conclude that substantial evidence exists to support the Commission's finding that a de facto termination occurred.
We conclude, under the facts of this case, that the Commission did not exceed its statutory or constitutional authority in finding that Kawasaki's actions constituted *797 a termination of D.K.D.'s franchise without the 60-days written notice section 5.02(3) requires and in imposing civil penalties for this violation of the Code. Accordingly, we overrule Kawasaki's first point of error.

Agency Adjudication of Private Claims
In its second point of error, Kawasaki contends that the trial court erred in failing to determine that the Commission exceeded its statutory and constitutional authority in adjudicating D.K.D.'s claims under section 5.02(14). See APTRA § 19(e)(2). Kawasaki asserts that these claims for payment of parts, accessories, and signs are contract claims that the Commission has no authority to adjudicate. The Commission determined that Kawasaki had not made the payments, as the Code required, and ordered the company to pay D.K.D. the amount of $51,895.71.
The relevant version of section 5.02(14) provides that it is unlawful for a manufacturer to fail to pay the dealer, upon termination of the franchise, for unsold new motor vehicles, parts, accessories, signs, special tools and service equipment, and the costs of the repurchase. A manufacturer that fails to make such payments within six months of termination is liable for "the greatest of dealer cost, fair market value, or current price of the inventory," interest, attorney's fees, and costs. Act of May 20, 1987, 70th Leg., R.S., ch. 357, sec. 24, § 5.02(14), 1987 Tex.Gen.Laws, 1781, 1790-91 (Tex.Rev.Civ.Stat.Ann. art. 4413(36), § 5.02(14), since amended, current version at § 5.02(16)). Kawasaki argues that neither this section nor other Code provisions grant the Commission authority to order payment to the dealer. We agree.
Kawasaki first argues that the Code does not grant the Commission authority to order payments under section 5.02(14). Second, even if the Commission had that authority, Kawasaki asserts that the adjudication of these private claims is left to the courts and that the Commission's adjudication of private claims violates the doctrine of separation of powers. See Tex. Const. art. II, § 1 & art. V, § 1.
An agency may exercise only those specific powers that the law confers upon it in clear and express language. As a general rule, the legislature impliedly intends that an agency should have whatever power is reasonably necessary to fulfill a function or perform a duty that the legislature has expressly placed in the agency. Texas Dep't of Human Servs. v. Christian Care Ctrs., Inc., 826 S.W.2d 715, 719 (Tex. App.Austin 1992, writ denied); Sexton v. Mount Olivet Cemetery Ass'n, 720 S.W.2d 129, 137-38 (Tex.App.Austin 1986, writ ref'd n.r.e.). Here, Kawasaki argues that the remedy the Commission ordered is not within the agency's authority.
The Commission replies that the Legislature has either expressly or impliedly authorized the Commission to adjudicate claims under section 5.02(14). The Commission argues that the grant of powers contained in sections 3.01 and 3.03 of the Code constitutes specific statutory authority to adjudicate section 5.02(14) claims.[7] Alternatively, the Commission argues that the power to adjudicate these claims is implied by the Commission's duties to administer the Code provisions and to insure that the distribution and sale of motor vehicles is conducted in compliance with the Code. The Commission further argues that the issues adjudicated under section 5.02(14) concerned rights created by statute rather than common-law rights and, thus, could be properly delegated to an agency *798 without violation of separation of powers principles.
The legislature has expressly provided mechanisms by which the Commission may enforce violations of Code provisions. Pursuant to section 6.01, the Commission may assess a civil penalty against a person who the Commission finds has violated the Code.[8] Pursuant to section 6.01A, the Commission may also issue a cease and desist order to stop ongoing violations of the Code.[9] The Legislature has not, however, expressly granted the Commission authority to order a distributor to pay the dealer amounts owed pursuant to section 5.02(14).[10]
In the immediate case, the statute contains only general grants of authority and does not provide a procedure to compel compliance with section 5.02(14).[11] This Court has previously discussed the general authority of administrative agencies:
It is axiomatic that such agencies are creatures of statute and have no inherent authority. They may, therefore, exercise only those specific powers conferred upon them by law in clear and express language, and no additional authority will be implied by judicial construction. However, with respect to a power specifically granted the agency, the full extent of that power must be ascertained with due regard for the rule that the Legislature generally intends that an agency should have by implication such authority as may be necessary to carry out the specific power delegated, in order that the statutory purpose might be achieved. Moreover, the Legislature impliedly intends, as a general rule, that an agency should have whatever power is necessary to fulfill a function or perform a duty placed expressly in the agency by the Legislature. The Legislature does not intend that agency functions be an exercise in futility....
The agency may not, however, on a theory of necessary implication from a specific power, function, or duty expressly delegated, erect and exercise what really amounts to a new and additional power or one that contradicts the statute, no matter that the new power is viewed as being expedient for administrative purposes.
Sexton v. Mount Olivet Cemetery Ass'n, 720 S.W.2d 129, 137-38 (Tex.App.Austin 1986, writ ref'd n.r.e.) (emphasis in original) (citations omitted); see also Texas Dep't of Human Servs. v. Christian Care Ctrs., Inc., 826 S.W.2d 715, 719-20 (Tex.App. Austin 1992, writ denied). We conclude that the grant of powers to the Commission in sections 3.01 and 3.03 is general in nature and does not convey the express power to order payments to dealers pursuant to section 5.02(14) in Commission proceedings. We now must examine whether these sections imply such a power. The actions of the Commission in ordering Kawasaki to make payments to D.K.D. can be described as enforcement or adjudicatory in nature.
Generally, enforcement powers cannot be implied. Harrington v. Railroad Comm'n, 375 S.W.2d 892, 894-95 (Tex. 1964); Public Util. Comm'n v. Houston Lighting & Power Co., 715 S.W.2d 98, 103 (Tex.App.Austin 1986), modified on other grounds, 748 S.W.2d 439 (Tex.1988), appeal dism'd, 488 U.S. 805, 109 S.Ct. 36, 102 L.Ed.2d 16 (1988) (absent express authority Commission had no implied power to impose a rate-of-return penalty for utility mismanagement); but see City of Brownsville *799 v. Public Util. Comm'n, 616 S.W.2d 402, 408 (Tex.Civ.App.Texarkana 1981, writ ref'd n.r.e.); Gluck v. Texas Animal Health Comm'n, 501 S.W.2d 412, 414-15 (Tex.Civ.App.San Antonio 1973, writ ref'd n.r.e.). The courts have also declined to imply the power to adjudicate private claims. Absent statutory authority, the Railroad Commission has not been allowed to adjudicate contractual rights of individuals or title to land. See Trapp v. Shell Oil Co., 198 S.W.2d 424, 437 (Tex.1946); Railroad Comm'n v. Rau, 45 S.W.2d 413, 416 (Tex.Civ.App.Austin 1931, writ dism'd).
We believe that the adjudication of claims under section 5.02(14) is not necessary either to carry out any specific power granted the Commission, or to fulfill any function or duty expressly imposed on the Commission. Absent an express delegation by the Legislature, we decline to imply such a power. The Commission clearly could make a finding of violations of section 5.02(14) and impose civil penalties for such violations pursuant to section 6.01. However, it could not adjudicate the private dispute between Kawasaki and D.K.D. We conclude that the Legislature did not expressly or impliedly grant to the Commission the power to adjudicate claims between franchisors and franchisees under section 5.02(14) or to enforce that section by ordering payment by the franchisor to the franchisee. Therefore, we sustain Kawasaki's second point of error.
Having reversed the trial court's judgment as to the section 5.02(14) claims for the above reasons, we do not reach Kawasaki's remaining arguments under this point.

CONCLUSION
We reverse the district court's judgment and render judgment that the proceeding be remanded to the Commission for further proceedings consistent with this opinion.
