In Firsov v. United Airlines, Judge Freeman denied Firsov’s sanctions motion but granted Lufthansa’s sanctions request and ordered briefing on fees.

Who this affects

Sergey Firsov’s sanctions motion was denied, and the court granted Lufthansa’s request for sanctions against him. Lufthansa was ordered to submit information about the attorneys’ fees incurred in opposing the motion, with Firsov allowed to respond.

What happened

In Sergey Firsov v. United Airlines, Inc., et al., pro se plaintiff Sergey Firsov asked the court to sanction Lufthansa’s lawyers under Federal Rule of Civil Procedure 11. He challenged their use of public litigation records, their handling of a hearing-date request, and an address in a filing.

The court found that none of Firsov’s reasons supported sanctions. It also found that Firsov had inaccurately described the ruling in a prior related proceeding and agreed that filing this sanctions motion warranted sanctions against him.

Judge Freeman denied Firsov’s motion, granted Lufthansa’s request for sanctions, and ordered Lufthansa to provide information about the attorneys’ fees it incurred opposing the motion. The court did not set a fee amount in this order.

Case
Firsov v. Airlines · No. 5:25-cv-03784
Judge

Date
Dec. 1, 2025

Background

Pro se plaintiff Sergey Firsov moved for sanctions against counsel for Defendant Deutsche Lufthansa Aktiengesellschaft under Federal Rule of Civil Procedure 11. Lufthansa opposed the motion.

Firsov raised four grounds. He argued that Lufthansa’s counsel improperly investigated his family life by filing a declaration attaching the California Judicial Council List of Vexatious Litigants, which included his name. He also argued that counsel acted in bad faith by attaching a LexisNexis summary of litigation involving him. Firsov further argued that counsel ignored his request to change a hearing date because he would be on vacation. Finally, he asserted that counsel misstated Lufthansa’s registered-agent address by omitting “Suite 700.”

Legal standard

Rule 11 requires attorneys to certify that pleadings and motions are supported by the facts, have a reasonable legal basis, and are not filed for an improper purpose. Sanctions are reserved for rare cases involving clearly frivolous, legally unreasonable, unsupported, or improperly motivated filings. The court also stated that a groundless Rule 11 motion can itself be sanctionable and that Rule 11 sanctions may apply to a person proceeding without a lawyer.

Court’s analysis

The court rejected all four grounds in Firsov’s motion. It said that the vexatious-litigant list and the LexisNexis litigation summary were matters of public record. The court also stated that Lufthansa’s failure to agree to a hearing-date change was not sanctionable because Firsov could have filed an administrative motion requesting a new date. Regarding the registered-agent address, the court found that Firsov offered no factual support for inferring that counsel intentionally misrepresented the address by omitting “Suite 700.”

The court then considered Lufthansa’s request to sanction Firsov for filing the motion. It found that Firsov falsely represented that another court had ruled that he could seek emotional-distress damages for his dogs. According to the court, the cited prior related proceeding instead involved permission to amend claims after Firsov initially named the wrong defendant. The court also noted that Firsov had recently been sanctioned in that earlier round of the case for misrepresenting the court’s rulings. The court agreed that sanctions were required to deter what it called Firsov’s vexatious and abusive conduct.

Disposition

The court denied Firsov’s motion for sanctions. It granted Lufthansa’s request for sanctions based on Firsov’s filing of the motion and warned that future abusive or bad-faith filings could result in additional sanctions. The court ordered Lufthansa to file, within seven days, a brief and counsel’s declaration addressing the reasonable attorneys’ fees incurred in opposing the sanctions motion, including counsel’s hourly rates and hours worked. Firsov was given one week to respond. The order did not determine the amount of fees.
