March 12, 2026 — This Women’s History Month, Kellogg Hansen partner Alejandra Ávila spoke with The Appellate Project about her career and shared her advice for how to build a sustainable appellate practice. In “A Day in the Life of a Partner,” Alejandra reflects on her work at the firm.  “[T]here is no ‘typical’ day or week,” she explained.  “I manage all kinds of cases. One day I’m writing a Supreme Court brief about bankruptcy, the next day I’m defending a deposition in an antitrust case, and the next day I’m working with an expert on a question of foreign law. I chose this job because it keeps me on my toes, every day is different, and I am always learning something new.” Alejandra also emphasized the importance of mentoring and strengthening advocacy skills.  As a partner, Alejandra tries to emulate the balanced managerial approach that helped her grow and improve, entrusting associates and staff with substantive responsibilities and empowering them with the tools they need to handle their matters. “I strongly believe that cultivating young talent is an investment that pays off because it allows upper management to delegate efficiently, increases morale across the team, and improves work product overall. Most important of all: it’s good practice to be kind to your colleagues.” Kellogg Hansen is a preeminent trial and appellate litigation firm founded on the idea that talent, creativity, and hard work achieve the best results for clients. Formed in the spring of 1993 by law school classmates Michael Kellogg, Peter Huber, and Mark Hansen, our firm has grown over the past 31 years–with each year proving that our founding principle holds true. Today, Kellogg Hansen has more than 100 attorneys, and boasts an extensive record of success for our clients. Our highly credentialed and motivated lawyers offer businesses, individuals, and governments sound counsel and innovative solutions to complex disputes and high-stakes matters. We have substantial experience trying cases to verdict at trial, arguing matters before the United States Supreme Court and other appellate courts, and representing businesses and individuals in parallel proceedings before state and federal courts, agencies, and arbitration panels. We represent both plaintiffs and defendants, providing our clients with a balanced view of both sides of litigation. We are most proud of the exceptional results we achieve for our clients–we have won multiple verdicts in excess of $1 billion, and successfully defended clients against similarly large damages claims.

February 3, 2026 — Partner Josh Branson and the Kellogg Hansen team have been spotlighted in Law.com’s Litigator of the Week coverage for their work in long-running Antiterrorism Act litigation arising from terrorist attacks in Iraq. On January 23, 2026, the D.C. Circuit delivered a crucial victory for Gold Star Families and wounded veterans in an important Antiterrorism Act case concerning 2008-era Iraq.  Kellogg Hansen, along with co-counsel Sparacino PLLC, represents the families of nearly 400 Americans who were killed or wounded in Iraq; clients sued five major pharmaceutical and medical equipment companies for allegedly making corrupt payments to the terrorist group responsible for those attacks.  After the district court dismissed the claims, the D.C. Circuit reversed in full.  The next steps should be discovery, summary judgment, and trial. The American Lawyer previously recognized Josh as Litigator of the Week for this case in 2022, when the D.C. Circuit first reversed the dismissal of these claims. Kellogg Hansen has been leading the case since 2017.  During the course of the eight-years-and-counting litigation, more than 20 plaintiffs have died.  The Kellogg Hansen team includes David Frederick, Andrew Goldsmith, and Derek Reinbold. The case and this most recent appellate victory have also drawn attention from leading legal media, including coverage as Ruling of the Week in Original Jurisdiction\'s Judicial Notice and recognition in Law360’s Legal Lions feature. Kellogg Hansen is honored to continue representing the families of Americans injured or killed by terrorist attacks. Atchley v. AstraZeneca UK Ltd., No. 20-7077 (D.C. Cir. Jan. 23, 2026)..

January 16, 2026 — The recent ruling by Judge James Boasberg, which found that the FTC failed to demonstrate that Meta illegally monopolized the personal social networking market, marks a landmark moment in modern antitrust litigation. In a recent interview with Global Competition Review, Kellogg Hansen partner Aaron Panner shared his reflections on the five-year journey as outside counsel for Meta. The victory, he notes, was not just a win for the company, but a testament to the evolving nature of Section 2 cases. A Team Effort Under Pressure: Panner emphasized that the \"gratifying\" result was the product of a massive collaborative effort. Led by Mark Hansen, the legal team worked hand-in-hand with Meta’s in-house counsel and executives. This synergy allowed the team to develop the complex facts necessary to navigate a trial of this magnitude. The Weight of Data: Why Meta Won: What resonated most with the court? According to Panner, it came down to \"quantitative evidence of substitution.\" Natural Experiments: Data from events like the TikTok outage provided a real-world look at how users shift their time between apps. Empirical Analysis: Controlled experiments (such as those by Professor List) offered the court concrete proof of a competitive market. Competitive Reality: Documents and testimony showed that Meta’s investment decisions were driven by the need to respond to intense pressure from rivals. The Human Element of the Trial: Beyond the data, Panner highlighted the importance of executive testimony. Working with Meta’s top executives allowed the legal team to translate a \"very complicated\" business into an educational experience for the court. And cross-examination of competitors revealed the \"intense competition\" Meta faces—facts that were ultimately reflected in the competitors\' own internal documents. The Future of Section 2 Cases: The implications of this ruling extend far beyond Meta. Panner predicts that Judge Boasberg’s focus on market definition and empirical evidence will influence how antitrust lawyers develop and try cases for years to come. In an era of \"big tech\" scrutiny, this case reinforces that at the end of the day, hard data and a clear narrative of competitive response remain the strongest defense.
