Background

Johnnie Mae Cullins worked for MGM Grand Detroit, LLC, first as a pit clerk and later as a security officer. After knee-replacement surgery, she experienced difficulty standing for long periods and sought assignments requiring less standing. Under a collective bargaining agreement, security officers had to pass an annual physical-agility test without accommodation. Cullins failed the test twice in 2019 and was reassigned to an ID-checker position, which had less stringent physical requirements.

Cullins requested accommodations for restrictions involving standing, lifting, kneeling, running, and using stairs. She testified that MGM denied her repeated requests for a chair while she worked as an ID checker. After later taking medical leave for foot surgery and mental-health treatment, Cullins remained unable to return to work. MGM granted several leave extensions but terminated her employment in May 2022 after her physician reported that she remained totally vocationally disabled.

Cullins sued, alleging that MGM failed to accommodate her disability under Michigan’s Persons with Disabilities Civil Rights Act and retaliated against her for exercising rights under the Worker’s Disability Compensation Act. The Wayne Circuit Court granted MGM summary disposition, concluding that Cullins had not shown that her disability was unrelated to her ability to perform essential job duties, had not submitted a written request for a chair, and had not established a causal connection between protected workers’ compensation activity and her termination.

The Court’s Holding

The Michigan Court of Appeals affirmed. It agreed that the trial court had improperly treated as undisputed a statement in a psychiatric evaluator’s report suggesting that Cullins had worked four hours sitting and four hours standing. Cullins’s testimony created a factual dispute over whether MGM had provided such an accommodation. That error did not warrant reversal, however, because the disputed statement was immaterial to the trial court’s stated grounds for dismissing the disability-accommodation claim.

The court also rejected Cullins’s challenge to the trial court’s consideration of other employees’ agility-test results. The results could be considered at summary disposition because there was a plausible basis for admitting their substance at trial, even if the materials were not yet in admissible form. More importantly, the results were immaterial to the trial court’s reasons for dismissing the retaliation claim: Cullins had not established causation, and no reasonable factfinder could infer retaliatory motive from her termination after MGM repeatedly extended her leave while she remained medically unable to return.

Ultimately, Cullins’s appellate brief did not address the actual grounds on which the trial court dismissed either claim. Because her evidentiary arguments would not undermine those independent grounds even if successful, she was not entitled to appellate relief.

Key Takeaways

  • An appellant must directly challenge the trial court’s dispositive reasoning; attacking immaterial evidence does not establish entitlement to reversal.
  • Evidence considered at summary disposition must be substantively admissible, but it need not already be presented in admissible form if a plausible basis exists for its admission at trial.
  • A trial court’s factual error does not require reversal when the disputed fact played no role in the grounds supporting dismissal.

Why It Matters

The decision emphasizes the importance of matching appellate arguments to the precise grounds supporting the judgment below. Even potentially meritorious evidentiary objections will not produce reversal when they do not affect the trial court’s controlling analysis.

For employment litigants, the opinion also illustrates the evidentiary burdens attached to disability-accommodation and workers’ compensation retaliation claims, including proof that a disability is unrelated to essential job functions and that protected activity caused the challenged employment action.
