PER CURIAM.
In this case involving a claim for unemployment benefits, we must determine whether the lower courts applied the proper standard for reviewing determinations made by an administrative agency. Specifically, claimant was terminated from her employment for willfully violating her employer's computer use policy. The state's unemployment agency denied her claim for unemployment benefits and this decision was affirmed by an administrative law judge (ALJ). In turn, the Michigan Compensation Appellate Commission (MCAC) affirmed the ALJ's decision, holding that the decision was made in conformity with the facts as developed at the hearing and properly applied the law to the facts. On appeal to the circuit court, however, the court concluded that, because claimant violated her employer's policy to assist a customer, the conduct did not warrant a denial of unemployment benefits. The Court of Appeals, in a published opinion, affirmed the circuit court, agreeing that claimant's violation of her employer's rules was not sufficiently egregious to deny the claimant benefits.
We reverse the judgment of the Court of Appeals and we reinstate the judgment of the MCAC. Both the Wayne Circuit Court and the Court of Appeals applied an incorrect standard of review by substituting their own assessment of the relative severity of the claimant's violation of her employer's rules for the assessment of the MCAC. The MCAC's assessment of the claimant's conduct was made within the correct legal framework and, therefore, was authorized by law and was not contrary to law, and the courts below improperly reweighed the evidence in order to reach a different assessment in violation of Const. 1963, art. 6, § 28 and MCL 421.38(1).
I. BASIC FACTS AND PROCEEDINGS
Claimant, Carnice Hodge, was employed as a security guard with U.S. Security Associates, Inc (USSA). On November 11, 2008, shortly after being hired, Hodge signed an acknowledgement of USSA's "Security Officer's Guide," which provided, in relevant part, that the "[u]nauthorized use of client facilities or equipment, including copiers, fax machines, computers, the internet, forklifts, and vehicles" may result in immediate termination. USSA had a contract to provide security at Detroit Metropolitan Airport, and she was assigned to work at the airport. Despite acknowledgement of USSA's "Security Officer's Guide," on January 27, 2011, Hodge accessed the airport's computer system in order to assist a passenger by retrieving departure information.
The parties agree to the following facts: (1) USSA had a policy that prohibited employees from accessing airport computers, (2) Hodge knew of this policy, (3) Hodge had violated this policy on some occasions in the past, (4) Hodge never received any instruction or approval to violate this policy, and (5) Hodge violated this policy on January 27, 2011, when she accessed the airport's computer system in order to retrieve departure data for a passenger.
Given these facts, the ALJ concluded that Hodge's reason for using the airport computer was irrelevant because USSA's policy prohibited computer access for any reason. The ALJ concluded that the unauthorized computer access constituted misconduct, disqualifying Hodge from benefits under MCL 421.29(1)(b), because Hodge "was discharged for reasons which would constitute behavior beneath the standard the [e]mployer had reason to expect...."1
The MCAC upheld that decision, ruling that the ALJ's decision conformed to the facts as developed at the administrative hearing and that the ALJ properly applied the law to the facts.
II. APPLICABLE STANDARDS OF REVIEW
Michigan's Constitution sets forth the guiding principles of how courts should review a decision of an administrative body. It provides:
All final decisions, findings, rulings and orders of any administrative officer or agency existing under the constitution or by law, which are judicial or quasi-judicial and affect private rights or licenses, shall be subject to direct review by the courts as provided by law. This review shall include, as a minimum, the determination whether such final decisions, findings, rulings and orders are authorized by law; and, in cases in which a hearing is required, whether the same are supported by competent, material and substantial evidence on the whole record.[2]
Consistent with this provision, the Michigan Employment Security Act, MCL 421.1 et seq., expressly provides for the direct review of unemployment benefit claims. Specifically, MCL 421.34 addresses an appeal from an ALJ to the MCAC. MCL 421.38 then addresses an appeal from the MCAC to a circuit court:
The circuit court ... may review questions of fact and law on the record made before the administrative law judge and the Michigan compensation appellate commission involved in a final order or decision of the [MCAC], ... but the [circuit] court may reverse an order or decision only if it finds that the order or decision is contrary to law or is not supported by competent, material, and substantial evidence on the whole record.[3]
Using this standard, a circuit court must affirm a decision of the ALJ and the MCAC if it conforms to the law, and if competent, material, and substantial evidence supports it. A reviewing court is not at liberty to substitute its own judgment for a decision of the MCAC that is supported with substantial evidence.4 The Court of Appeals then reviews a circuit court's decision "to determine whether the lower court applied correct legal principles and whether it misapprehended or misapplied the substantial evidence test to the agency's factual findings...."5
III. ANALYSIS
We conclude that both the circuit court and Court of Appeals erred by departing from the applicable standard of review.
The circuit court determined that Hodge ultimately had to make a decision between two conflicting policies: one, to not use the airport's computer system, and two, to assist passengers by retrieving departure information.6 The lower court record, however, does not contain any evidence of a stated policy to assist passengers by retrieving departure information. Even if such a policy can be implied from the record, the ALJ determined, in a factual finding, that the most weight should be given to the expressly stated policy against access of the airport's computer system. Thus, the circuit court erred when it discounted the stated policy of Hodge's employer and, instead, credited Hodge with complying with a nonexistent policy of assisting passengers by retrieving departure information.
Likewise, the Court of Appeals erred by determining that Hodge's act of helping a passenger actually benefitted USSA.7 The panel reached this conclusion despite the ALJ's contrary finding that Hodge's violation was so severe that it went against USSA's interest. Instead of determining whether factual assessments made by the agency were supported by substantial evidence, both the lower courts engaged in an unbridled effort to reevaluate the ALJ's factual findings.
The ALJ, the only adjudicator who actually heard testimony and observed the demeanor of the witnesses while testifying, reviewed all the evidence in the record and made findings of fact based on the credibility of witnesses and weight of the evidence. The ALJ ultimately determined that Hodge's violation of the computer policy was a deliberate disregard of USSA's interest and that Hodge was discharged for reasons that would constitute behavior beneath the standard expected of employees. Thus, the ALJ disqualified Hodge from unemployment benefits for committing misconduct, in accordance with MCL 421.29(1)(b), and most prominently defined in Carter, 364 Mich. at 541, 111 N.W.2d 817.8
"The ALJ reached this conclusion by giving weight to evidence within the lower record. The lower courts should have given deference to the ALJ and the MCAC by reviewing those decisions only to ensure conformity with the law and the existence of competent, material, and substantial evidence. In sum, the lower courts improperly discounted the ALJ's findings to apply their own factual assessments, in violation of Const. 1963, art. 6, § 28 and MCL 421.38(1).
IV. CONCLUSION
The application for leave to appeal the July 15, 2014 judgment of the Court of Appeals is considered and, pursuant to MCR 7.302(H)(1), in lieu of granting leave to appeal, we reverse the judgment of the Court of Appeals and we reinstate the judgment of the Michigan Compensation Appellate Commission.
