A federal appeals court has ruled that a law firm's use of artificial intelligence (AI) tools does not automatically mean its legal fees should be reduced. The court rejected an argument from a losing party that the technology had led to inflated legal bills. The decision by the 10th US Circuit Court of Appeals upholds a legal fee award of $114,663.11 given to defence lawyers in a trade-secrets dispute. The court said anyone challenging a legal bill must provide clear evidence of overcharging. Simply pointing out that a law firm used automated legal software is not enough. Writing for a unanimous three-judge panel, Circuit Judge Carolyn McHugh said AI can make legal research and document writing faster. However, the responsibility to prove that using the technology resulted in unreasonable charges lies with the party challenging the bill. The ruling sets an early example of how courts may deal with the use of automated tools in the legal profession. It makes clear that courts will not automatically assume that using software means lawyers have charged for too many hours.
Dismissal leads to fee battle
The dispute over legal fees began with a trade-secrets lawsuit filed by Flux Drive Inc. The company sued defendants from another state, accusing them of taking its privately owned technology without permission. The case never went to trial on the main claims. A federal district court judge in Colorado dismissed the lawsuit after finding that the court did not have legal authority over the Illinois-based defendants. After the case was dismissed, the defendants asked to recover the money they had spent defending themselves. They were represented by the law firm Brownstein Hyatt Farber Schreck, which submitted detailed records of its legal work and charges to the district court. The trial judge reviewed the records and found that the hours worked and hourly rates were reasonable under federal rules. The judge then ordered Flux Drive to pay $114,663.11 in legal fees. Flux Drive appealed the decision to the 10th Circuit. The company argued that the law firm had used artificial intelligence software while handling the case. It claimed that because AI tools can complete tasks faster, the number of hours charged by the lawyers was too high and placed an unreasonable financial burden on the company.
Burden of proof on challenger
The 10th Circuit rejected Flux Drive's argument and upheld the district court's original legal fee award in full. The panel included Circuit Judges Scott Matheson and Richard Federico, along with Judge McHugh. The judges stressed that trial courts have wide powers to decide whether legal fees are reasonable because they directly oversee the cases. "The district court reviewed the time entries and found them reasonable," the panel stated in its opinion. It also noted that Flux Drive had failed to point to specific billing entries that were repeated, false or inflated because of the use of technology. Reuters reported on 2 November that the ruling sets a clear standard for future disputes over legal fees involving technology. Although judges recognise that AI can speed up legal work, anyone seeking to reduce a legal fee award must provide direct evidence showing that the hours charged were unreasonable. Legal analysts say the ruling does not give law firms complete freedom to charge clients for AI-assisted work without question. If someone challenging a bill can show that software completed most of a task in a few minutes while the law firm charged for several hours of manual work, courts still have the power to reduce the fees. However, under the 10th Circuit's standard, simply showing that a law firm used AI software is not enough to overturn a trial court's decision on legal fees.
Growing scrutiny of legal technology
The decision comes at a time when courts are paying closer attention to how law firms use artificial intelligence in their daily work. Over the past two years, federal and state courts across the United States have introduced stricter reporting requirements. These steps followed several cases in which lawyers submitted court documents containing fake legal references generated by AI chatbots that had not been properly checked. The 10th Circuit has also recently proposed changes to its rules. Under these proposed changes, lawyers would have to formally confirm that a human attorney had independently checked all legal authorities cited in their appeals court filings. These administrative rules are aimed at maintaining accuracy and preventing lawyers from misleading courts. However, the Flux Drive case deals with a different issue. It focuses on how law firms charge clients when they use technology to complete legal work. By upholding the $114,663 award, the court confirmed that existing methods for deciding reasonable legal fees remain valid, whether a law firm uses traditional research methods or modern software. The 10th Circuit's formal order leaves the district court's fee decision unchanged, bringing the legal dispute between Flux Drive and the defence lawyers to an end.
