Laguana v. United Airlines, Inc.

The United States Court of Appeals for the Ninth Circuit recently issued a "not for publication" memorandum disposition in *Laguana v. United Airlines, Inc.* on July 8, 2026. This decision likely affirmed the District Court of Guam's grant of summary judgment in favor of United Airlines in a case involving claims of disability discrimination and hostile work environment brought by a former employee under the Americans with Disabilities Act (ADA). As an unpublished disposition, the Ninth Circuit's ruling lacks precedential value and cannot be cited as binding authority, except in limited circumstances such as those involving the doctrines of law of the case, res judicata, or collateral estoppel. This outcome underscores the procedural hurdles and substantive challenges faced by plaintiffs in employment discrimination litigation against air carriers, particularly when appealing adverse summary judgment rulings.

On July 8, 2026, the United States Court of Appeals for the Ninth Circuit filed a "not for publication" memorandum disposition in the case of *Joseph Laguana v. United Airlines, Inc.*, bearing appellate docket number 25-3978. This procedural designation signifies that while the Ninth Circuit has rendered a decision, its reasoning is not intended to establish binding precedent for future cases. The disposition likely addresses an appeal from the District Court of Guam, which previously granted summary judgment to United Airlines in a lawsuit alleging disability discrimination and hostile work environment under the Americans with Disabilities Act (ADA).

For legal practitioners, the issuance of an unpublished memorandum disposition carries significant implications. Such decisions, though resolving the immediate dispute between the parties, offer limited guidance on the development of legal principles and cannot typically be cited as authoritative precedent in subsequent litigation. This article will delve into the background of the underlying District Court case, explore the procedural significance of a "not for publication" ruling in the Ninth Circuit, and discuss the broader implications for attorneys navigating employment disputes within the aviation industry.

The genesis of *Laguana v. United Airlines, Inc.* lies in a civil action filed in the District Court of Guam (Case No. 1:22-cv-00027), where Joseph Laguana, a former customer service employee, brought claims against United Airlines. Laguana alleged disability discrimination and a hostile work environment, primarily stemming from workplace treatment and his response to the COVID-19 pandemic. Specifically, Laguana, who suffered from asthma, sought accommodations such as remote work and social distancing, and subsequently took extended medical leave due to concerns about COVID-19 exposure. The District Court ultimately granted summary judgment in favor of United Airlines, dismissing Laguana's claims, including those for wrongful termination, failure to accommodate, constructive discharge, and hostile work environment.

The legal framework for Laguana's claims is primarily the Americans with Disabilities Act of 1990 (ADA), 42 U.S.C. § 12101 et seq., which prohibits discrimination against individuals with disabilities in employment. The District Court's decision would have involved an application of the ADA's requirements for establishing a prima facie case of discrimination, the employer's duty to provide reasonable accommodations, and the standards for proving a hostile work environment. The Ninth Circuit's review of such a decision would typically involve assessing whether the District Court correctly applied the summary judgment standard, which requires determining if there is a genuine dispute as to any material fact and if the movant is entitled to judgment as a matter of law. Notably, while the Airline Deregulation Act (ADA), 49 U.S.C. § 41713, broadly preempts state laws related to an air carrier's "prices, routes, or services," it generally does not preempt state or federal employment discrimination claims, which fall outside the scope of economic regulation.

The Ninth Circuit's disposition in *Laguana v. United Airlines, Inc.* as a "not for publication" memorandum is a critical procedural detail. Under Ninth Circuit Rule 36-3, such dispositions are not binding precedent and generally cannot be cited by or to courts within the circuit, except in limited circumstances such as when relevant under the doctrines of law of the case, res judicata, or collateral estoppel. This practice, common across federal appellate courts, is primarily a mechanism for managing heavy caseloads by allowing the court to resolve cases that do not present novel legal questions or require the development of new law through routine application of established precedent.

Given the District Court's grant of summary judgment, the Ninth Circuit's review would have focused on whether Laguana presented sufficient evidence to create a genuine dispute of material fact regarding his ADA claims, or whether United Airlines was entitled to judgment as a matter of law. The District Court's opinion cited key Supreme Court cases establishing the summary judgment standard, such as *Celotex Corp. v. Catrett*, 477 U.S. 317 (1986), and *Anderson v. Liberty Lobby, Inc.*, 477 U.S. 242 (1986). The Ninth Circuit, by issuing an unpublished disposition, likely concluded that the District Court's application of these standards to Laguana's specific facts was correct and did not warrant a published opinion that would add to the body of precedential law.

While the specific reasoning of the Ninth Circuit's memorandum disposition is not publicly detailed, it is reasonable to infer that the appellate panel found no reversible error in the District Court's analysis of Laguana's ADA claims. This could mean that Laguana failed to establish a prima facie case of discrimination, that United Airlines demonstrated a legitimate, non-discriminatory reason for its actions that Laguana could not rebut, or that the requested accommodations were not reasonable under the ADA. The "not for publication" status suggests that the legal issues involved were straightforward applications of existing ADA jurisprudence, rather than complex questions requiring novel interpretation or clarification of the law.

Practitioners should understand that this disposition, while resolving the immediate appeal, does not alter or establish new legal principles regarding disability discrimination or hostile work environment claims against airlines. Its limited precedential value means that similar cases in the future will not be bound by this specific outcome, but rather by the published opinions and statutory interpretations that form the basis of the Ninth Circuit's underlying reasoning.

The Ninth Circuit's "not for publication" memorandum disposition in *Laguana v. United Airlines, Inc.* serves as a reminder of the procedural landscape governing federal appellate review, particularly in the context of employment litigation against air carriers. While the specific details of the Ninth Circuit's reasoning remain undisclosed due to its unpublished nature, the outcome likely affirms the District Court of Guam's grant of summary judgment, underscoring the significant evidentiary burdens plaintiffs face in proving disability discrimination and hostile work environment claims under the ADA.

For practicing attorneys, this case highlights the critical importance of robust factual development and meticulous adherence to legal standards at the trial court level. Given the limited precedential value of unpublished decisions, practitioners should continue to rely on published opinions and controlling statutes for guidance in similar cases. Monitoring future published decisions from the Ninth Circuit and other federal appellate courts remains essential for understanding evolving interpretations of the ADA and other employment laws as they apply to the dynamic aviation industry.
