An article in the Daily Journal about the recent Friends of the Los Angeles County Law Library gala, where Gibson Dunn partner Theane Evangelis and retired U.S. District Judge Dean Pregerson were honored with the 2026 Beacon of Justice Award, quotes extensively from Theane’s acceptance remarks.
The Daily Journal reports Theane’s emphasis on the broader responsibility of lawyers; she stated that “the law is a tool for justice” and that lawyers must “do good beyond the courtroom and in society as a whole.” It also notes that Theane underscored the importance of access to justice, describing the library as “a lifeline” for people seeking legal help. “The cornerstone for access to justice,” she said, “is access to reliable information.”
One of the country’s leading litigators, Theane is Co-Chair of Gibson Dunn’s global Litigation Practice Group and serves on the firm’s Executive Committee. She represents clients in federal and state courts throughout the nation and has argued and won high-profile, groundbreaking appeals across the country, including in the Supreme Court of the United States. She also serves on several non-profit and civic boards and is deeply committed to public service.
The Beacon of Justice Award recognizes contributions to the legal profession and to public service. Proceeds from the Friends of the Los Angeles County Law Library gala support the library’s free Access to Justice programs, which serve more than 120,000 people each year.
Gibson Dunn represented Cytokinetics, Incorporated in a public offering of 11,338,028 shares of common stock, including the full exercise of the underwriters’ option to purchase an additional 1,478,873 shares. The offering generated aggregate gross proceeds of approximately $805 million to Cytokinetics. Morgan Stanley, Goldman Sachs & Co. LLC, J.P. Morgan, and Jefferies acted as joint book-running managers for the offering.
Cytokinetics is a specialty cardiovascular biopharmaceutical company, building on its over 25 years of pioneering scientific innovations in muscle biology and advancing a pipeline of potential new medicines for patients suffering from diseases of cardiac muscle dysfunction.
The firm’s team included partners Ryan Murr and Branden Berns, of counsel Marie Kwon, and associates Jasmine Vitug and Kriti Hannon.
Partner Hillary Holmes recently told International Financing Review (subscription required) that the U.S. Securities and Exchange Commission’s proposal on optional semi-annual reporting would create a lighter burden for smaller companies: “Theoretically, it reduces the fees you’re paying your outside auditors, reduces the fees you’re paying your lawyers and all the things that go with quarterly reporting, and the cycle is less burdensome.”
Hillary also observed that, “For a small company, there is a particular crunch between the deadline for filing the annual report, which comes in mid-February, and the end of the first quarter when preparation for the quarterly report begins. Add in proxy season and the burden is heavy for small companies.”
In his article “AI Hones Bet-the-Company Cases Early, Scaling Back Discovery Woes” [PDF] for Bloomberg Law, partner Trey Cox writes that in large-scale litigation, general counsel must know “which 20 percent of the case will determine 80 percent of the risk rather than know about every document in a file.” He argues that “the rule is simple: Use AI to apply the 80/20 rule, then concentrate legal and business resources on those critical facts with ruthless discipline.”
Partner Patrick Pearsall has authored “The International Compensation Mechanism for Ukraine: Update on the Convention Establishing an International Claims Commission and the Register of Damage for Ukraine” for Just Security. Patrick was nominated by Ukraine’s President Zelensky to develop an international compensation mechanism for Ukraine and led the effort to propose and design Ukraine’s civil reparations strategy soon after Russia’s full-scale invasion.
He notes that Ukraine “is now transformed from a political proponent of the reparations framework into a formal participant in the legal architecture designed to implement it” and adds that “as the institutional architecture for deciding claims is consolidated, the evidentiary base feeding into it is being rapidly scaled up. Together, they signal a shift from largely symbolic institution-building toward a more functional system capable of handling the full scope—and scale—of Ukraine’s prospective reparations claims.”

Shout-out to Jeffrey Wall and Morgan Ratner, part of a group that recently left Sullivan & Cromwell to join Gibson, Dunn & Crutcher.

This week, the Eighth Circuit unanimously vacated the rules, holding Congress did not authorize the agency’s adoption of “disparate impact” liability. Ratner argued for the petitioners seeking to vacate the rule.

During a wide-ranging interview with Commercial Observer [PDF], partner Krystyna Blakeslee spoke about her work at Gibson Dunn on complex real estate transactions and how her experience as a former U.S. Marine instilled in her a sense of discipline and purpose that has provided stark advantages for herself, her colleagues, and her clients.
Krystyna also stressed that people always matter most, that “you have to both maintain and have really good relationships, and also do good work. You have to do both of those things.” She added: “The difference between a transaction that feels like a home run and one that just feels closed is how everyone behaved during the transaction, and how everyone feels about each other after that. I always want everyone, especially the people working directly for me, to feel really good about the work they did.”
A member of the firm’s Real Estate practice in New York, Krystyna focuses on commercial real estate finance and investment. She has led some of the country’s largest and most high-profile commercial real estate transactions in recent years.
