Few court opinions teach as much in as few pages as this one. A Secret Service employee complained about discrimination, her complaint went up on the office intranet, and her workload ballooned. Researchers who type “mogenhan v. napolitano 613 f.3d 1162 d.c. cir. 2010 retaliation” into a search bar usually want the same thing: what the court decided and why lawyers still cite it. Here is the plain-English version.

What Is Mogenhan v. Napolitano?
Mogenhan v. Napolitano is a 2010 federal appeals court decision on workplace retaliation. The D.C. Circuit reversed summary judgment on Ann Marie Mogenhan’s retaliation claim and sent it back for further proceedings.
The full citation is 613 F.3d 1162 (D.C. Cir. 2010), docket number 08-5457. Judge Merrick Garland wrote the opinion, decided July 27, 2010. Janet Napolitano is named only because she was Secretary of Homeland Security, the agency that oversees the Secret Service.
What Happened to Ann Marie Mogenhan?
Mogenhan worked for the Secret Service and had been hired in 1990 as a GS-9 management analyst. She suffered from migraines and filed complaints alleging discrimination.
Two events drove her retaliation claim. First, her supervisor posted her full complaint on a work intranet page. Second, less than a month later he raised her workload to five or six times that of her coworkers.
She said the extra work was meant to keep her too busy to file more complaints. The timeline is long. She sued in March 1998, and the appeals court ruled twelve years later.
What Did the Court Decide About Retaliation?
The court held that both actions could qualify as retaliation. A jury, not a judge, should decide whether they were retaliatory.
The lower court had granted summary judgment to the government. That means it ended the case before trial. The appeals court called that a mistake because the district court measured the conduct against the wrong yardstick. On the retaliation claim, the panel stressed that a reasonable employee might be dissuaded from filing a complaint if she feared being buried in work.
How Does the “Materially Adverse” Test Work?
An action is materially adverse if it might dissuade a reasonable worker from making or supporting a discrimination charge. Courts across the country quote this standard from the case.
The test comes from the Supreme Court’s Burlington Northern v. White decision in 2006. Mogenhan applied it to a federal employee’s claim. The key point is that retaliation does not need a firing or a demotion. Retaliatory conduct need not be as serious as discriminatory conduct to be actionable.
Why Did Her Accommodation Claim Fail?
The court affirmed summary judgment against her on the accommodation claim. It found no genuine dispute that the Service reasonably accommodated her disability.
That split result matters for anyone reading the case. Mogenhan lost one claim and won the other. Retaliation law protects the act of complaining, even when the underlying complaint does not succeed.
Why Does Mogenhan v. Napolitano Still Matter?
Courts still use the case to evaluate retaliation claims across the country. Other courts have cited it in disputes over increased workloads. The First Circuit later relied on it to explain that revealing an employee’s discrimination complaint to coworkers may chill protected activity.
Anyone tracking the mogenhan v. napolitano 613 f.3d 1162 d.c. cir. 2010 retaliation holding will find it in decisions well beyond Washington. The ruling also shows up in federal-employee cases, though it rests on a general retaliation standard.
A Reader Story
A reader we’ll call Dana worked in a county records office. Two weeks after she filed an internal complaint, her manager started assigning her every backlog project. Her coworkers’ desks stayed clear. Dana kept a dated log of each assignment. That log later helped her lawyer show a pattern, and the timing echoed the fact pattern in Mogenhan.
