Derrick McCoy v. Markwayne Mullin

This article examines the hypothetical appeal of *Derrick McCoy v. Markwayne Mullin, Secretary of Homeland Security*, before the United States Court of Appeals for the Seventh Circuit. While the named defendant, Markwayne Mullin, is not the current or a former Secretary of Homeland Security, the case provides a valuable framework for discussing the intricate legal landscape governing judicial review of federal agency decisions. The analysis delves into the procedural and substantive standards applied by federal courts, particularly the Seventh Circuit, when scrutinizing actions taken by the Department of Homeland Security under the Administrative Procedure Act. It highlights the critical importance of proper party identification, the standards of review, and the practitioner implications for challenging agency determinations.

The United States Court of Appeals for the Seventh Circuit is presented with a compelling, albeit hypothetical, case in *Derrick McCoy v. Markwayne Mullin, Secretary of Homeland Security*, No. 25-1533. This appeal, originating from a district court, ostensibly challenges a decision rendered by the Department of Homeland Security (DHS). While the named defendant, Markwayne Mullin, is a sitting U.S. Senator and has never served as the Secretary of Homeland Security, this article proceeds on the assumption that the case represents a challenge to an official action of the DHS, with the Secretary named in their official capacity. This discrepancy, while notable, does not diminish the opportunity to explore the substantive legal principles at play in federal appeals concerning administrative agency decisions.

Challenges to federal agency actions, such as those potentially arising from the Department of Homeland Security, are primarily governed by the Administrative Procedure Act (APA), 5 U.S.C. §§ 701-706. The APA establishes the framework for judicial review of agency decisions, allowing courts to set aside agency actions found to be arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law; contrary to constitutional right, power, privilege, or immunity; in excess of statutory jurisdiction, authority, or limitations, or short of statutory right; without observance of procedure required by law; unsupported by substantial evidence in a case subject to sections 556 and 557 of this title or otherwise reviewed on the record of an agency hearing provided by statute; or unwarranted by the facts to the extent that the facts are subject to trial de novo by the reviewing court. This statutory scheme ensures accountability and adherence to legal principles by federal agencies. Appeals from district court decisions concerning such agency actions then proceed to the circuit courts, where the appellate court reviews the district court's application of these APA standards.

In an appeal like *McCoy v. Mullin*, the Seventh Circuit would primarily review the district court's decision, not the agency's directly, applying established standards of review. Legal conclusions of the district court are reviewed *de novo*, while factual findings are reviewed for clear error. When assessing the underlying agency action, the Seventh Circuit would apply the APA's standards. For instance, an agency's factual findings are often reviewed under the 'substantial evidence' standard if the agency action was based on a formal adjudicatory hearing, or the 'arbitrary and capricious' standard for informal rulemaking and adjudication. The 'arbitrary and capricious' standard requires the agency to articulate a rational connection between the facts found and the choice made, ensuring the agency has examined the relevant data and articulated a satisfactory explanation for its action. The Seventh Circuit has consistently upheld that courts are not to substitute their judgment for that of the agency but must ensure the agency acted within its statutory authority and followed proper procedures.

Furthermore, the issue of the misnamed defendant, Markwayne Mullin, raises important procedural considerations. Federal Rule of Civil Procedure 25(d) addresses the substitution of a public officer who sues or is sued in an official capacity. It states that when a public officer ceases to hold office, the officer's successor is automatically substituted as a party. However, if the initial naming of the defendant was fundamentally incorrect (i.e., Markwayne Mullin was never the Secretary of Homeland Security), the plaintiff would likely face challenges regarding proper service and naming of the correct party. This could lead to dismissal if not rectified, as the proper defendant in a suit against a federal agency is typically the agency itself or the head of the agency in their official capacity. The Seventh Circuit would scrutinize whether the plaintiff exhausted all administrative remedies before seeking judicial review, a common prerequisite for challenging agency decisions.

Another critical aspect would be the level of deference afforded to the agency's interpretation of statutes it administers. Under the principles established in *Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc.*, courts generally defer to an agency's reasonable interpretation of an ambiguous statute, provided Congress has not directly spoken to the precise question at issue. This deference significantly impacts the scope of judicial review, limiting the court's ability to substitute its own interpretation for that of the agency. The Seventh Circuit, like other federal appellate courts, applies *Chevron* deference rigorously, particularly in complex areas of law such as immigration or national security, which often fall under DHS's purview.

The hypothetical appeal in *Derrick McCoy v. Markwayne Mullin, Secretary of Homeland Security* underscores the complexities inherent in challenging federal agency decisions in the U.S. judicial system. Practitioners must meticulously navigate the procedural requirements of the Administrative Procedure Act, including the exhaustion of administrative remedies and the precise identification of the proper governmental defendant. The standards of review applied by the Seventh Circuit—ranging from *de novo* for legal questions to the deferential 'arbitrary and capricious' or 'substantial evidence' standards for agency findings—demand a thorough understanding of administrative law principles and appellate procedure. Attorneys representing clients in such matters must be prepared to demonstrate not only that the agency erred but that its error falls within the narrow grounds for judicial intervention established by the APA and interpreted by controlling precedent. The outcome of such appeals often hinges on the agency's ability to articulate a reasoned basis for its decision, and the appellant's ability to demonstrate a clear legal or factual infirmity in that reasoning.
