When the Investigation File Cannot Prove the Investigation: Lessons from Brenyah v. Columbia Hospital

Most employers assume that if they respond to a harassment complaint by investigating promptly, interviewing employees, coaching the people responsible, and reporting back to the complainant, they have done what the law asks.

Most of the time, they are right.

In Brenyah v. Columbia Hospital, No. 25-40200 (5th Cir. June 23, 2026), however, the Fifth Circuit reversed summary judgment on a nurse’s hostile work environment claims even though the employer had taken many of those steps. The hospital’s problem was not simply whether it investigated. The problem was that, years later, it could not prove enough about what the investigation involved.

The case offers an uncomfortable but clarifying lesson: an investigation is only as strong as the record it leaves behind. And a response that does not actually end the harassment may turn out to be no remedy at all.

What Happened in Brenyah v. Columbia Hospital?

The complaint came from a registered nurse, a Black woman from Ghana, who reported that co-workers in her unit mocked her accent and food, made derogatory comments about Black employees, and treated other groups more favorably. She alleged that the conduct occurred regularly. A second Black nurse in the same unit raised similar allegations, and two managers handled the investigation.

For present purposes, that is the background that matters. The complainant filed suit, alleging a long list of claims, including discrimination, retaliation, and disability claims. The employer won summary judgment on most of the claims, and the Fifth Circuit affirmed those rulings on appeal. The hostile work environment claims were different. Those claims survived because the record left room for a reasonable jury to question whether the employer’s response was adequate.

Where Did the Investigation Fall Apart?

On paper, the managers’ response looks familiar: they investigated promptly, interviewed employees in the unit, coached the nurses who allegedly made the comments, met with the complainant about the findings, and offered her a transfer.

The difficulty was that the plaintiff produced evidence attacking the investigation’s credibility at nearly every step, and the employer’s own records could not answer back.

Start with the file. One investigator testified that there was an investigation file and that he had taken interview notes. But no investigation file or notes were produced in discovery. When an investigator testifies that documentation exists and the employer cannot produce it, the missing record becomes its own credibility problem.

The witness list also created problems. A Black employee in the unit, someone positioned to confirm or refute the allegations, was not interviewed. The investigation summary also omitted statements that allegedly corroborated the nurses’ complaints. A summary that includes only the evidence pointing one way begins to look less like diligence and more like advocacy.

The employer also appeared to drift from its usual practice. The complainants were not permitted to review or sign their interview statements, and no interview summaries were created, despite evidence that this departed from ordinary procedure. The investigators then gave conflicting testimony about the investigation and their interview records. Each discrepancy became another fact a jury could weigh.

The final problem was remedial. The managers told the complainant that “the cliques were not going anywhere,” and she testified that the behavior continued. That mattered because the legal question was not only whether the employer responded quickly. It was whether the response was reasonably calculated to end the harassment.

What Does “Prompt Remedial Action” Actually Require?

One of the legal elements of a hostile work environment claim asks whether the employer knew or should have known of the harassment and failed to take prompt remedial action. Employers often interpret that as a timing requirement. But prompt remedial action is also a quality requirement.

The response must be reasonably calculated to end the harassment. That means two things: (1) the employer must take steps designed to stop the conduct; and (2) the employer must be able to prove what it did through a reliable, contemporaneous record.

Notice what the Fifth Circuit did not hold. It did not decide that the investigation was inadequate as a matter of law. It held that a reasonable jury could find it inadequate. For the employer, that distinction offers little comfort. The difference between dismissal and trial turned on missing notes, an uninterviewed witness, omitted corroboration, deviations from normal practice, conflicting testimony, and evidence that the conduct continued.

How Do You Build an Investigation That Can Prove Itself?

Imagine the complaint you closed this morning becomes a lawsuit two years from now.

Could you produce a file that matches what your investigators will say under oath?

That file should show what was done, why it was done, and what the organization did next. It should include notes or summaries for each interview, a witness list that accounts for both corroborating and contrary evidence, and an explanation for why some witnesses were interviewed while others were not. It should show that statements were reviewed, signed, or memorialized consistently with ordinary practice.

It should also address the evidence that complicated the outcome, not just the evidence that supported it. And it should document the remedial plan, including any follow-up steps taken to determine whether the conduct actually stopped.

The point is not to create a perfect file for its own sake. The point is to create a file that can prove what the organization knew, what it did, why it did it, and whether the response worked.

The employer in Brenyah prevailed on most claims. But the hostile work environment claims survived because the record left too many questions about what the investigation involved and whether the response was adequate.

Before closing your next investigation, read the file the way a stranger will read it years from now, with the investigators’ depositions open beside it. The investigation you conducted matters less than the investigation you can prove.
