David A. Wolber is a Registered Foreign Lawyer (New York) and a partner of Gibson, Dunn & Crutcher LLP. He is a member of the firm’s International Trade, Financial Regulatory, and White Collar Defense and Investigations Practice Groups.

David assists clients around the world in understanding and navigating complex legal, compliance, reputational, political, and other risks arising out of the interplay of various international trade, national security, and financial crime laws and regulations, with particular expertise advising clients on economic and trade sanctions, export controls, foreign direct investment controls/CFIUS, U.S. outbound investment regulations, anti-money laundering (“AML”), and anti-bribery and anti-corruption (“ABC”) laws and regulations.

He routinely advocates on behalf of clients seeking CFIUS review, filing trade-related license applications, and U.S. outbound investment notifications, responding to governmental inquiries or subpoenas, submitting self-disclosures related to potentially non-compliant activity, and dealing with formal regulatory investigations or enforcement actions.

David is ranked as a leading International Trade attorney by Chambers Asia Pacific, Chambers Greater China Region, and Chambers Global: China. He is also ranked as a recommended lawyer for Regulatory by The Legal 500 Asia Pacific, in which interviewed clients remarked that David “is one of the rare lawyers in the region who has deep experience working in house on sanctions matters. He brings this experience to his practice to deliver workable advice that is a cut above,” and is “always reachable, contactable and offers very quick turnaround, sometimes within the day.” In the Chambers Greater China Region guide, a client noted that David “delivers practical, workable advice that is a cut above the textbook responses that other lawyers in the field may offer.”

David resumed his practice at Gibson Dunn in 2022 after taking a five-year hiatus to serve as in-house counsel to two major global financial institutions. From 2019 to 2022, he served as global financial crime counsel for HSBC, located in Hong Kong, where he advised the bank globally on compliance and risk mitigation strategies associated with various jurisdictions’ sanctions, export controls, AML, ABC, and national security laws and regulations, with particular focus on such issues affecting the bank in Asia. During his tenure with HSBC, David played a key role in advising and helping to guide the bank through the significant challenges posed to global financial institutions by the rising tensions in U.S.-China relations, and the related proliferation of law, regulation, and political action in the U.S., Hong Kong, and the People’s Republic of China.

From 2017 to 2019, David acted in a similar capacity at MUFG Bank, serving as sole financial crime counsel to the bank and key partner to the global financial crime compliance function headquartered in New York.

Prior to becoming an attorney, he spent more than 10 years in business strategy and development roles at Big Four accounting firms and major U.S. law firms.

David earned his Juris Doctor (magna cum laude) from Georgetown University Law Center in 2011. He received a Master of Science in Foreign Service from Georgetown University in 1997, where he focused on International Trade and Asian Political Economy, and his Bachelor of Arts from Rockhurst College in 1994.

David is a member of the New York State and District of Columbia Bars.

William E. Thomson is a litigation partner in the Los Angeles office of Gibson Dunn.  He is Co-Chair of the firm’s Transnational Litigation Practice Group, which Legal 500 US 2025 has again ranked Tier 1, International litigation.  He is also a member of the firm’s Appellate and Constitutional Law and Environmental Litigation and Mass Tort Practice Groups.  Bill’s practice focuses on federal and state appellate and Supreme Court litigation, and on strategic analysis and briefing in high-stakes cases in trial courts around the country.  Bill has extensive experience litigating and counseling on complex U.S. and cross-border matters before both trial and appellate courts in a broad range of contexts, including civil RICO, product liability and mass tort, foreign judgment recognition, First Amendment litigation, and class actions.  He has advised on and litigated matters implicating the competing laws of multiple U.S. jurisdictions and dozens of countries around the world, including supply chain liability risks, corporate separateness issues, and cross-border evidentiary actions pursuant to 28 U.S.C. § 1782.

In both the transnational and domestic contexts, clients regularly rely on Bill to help them develop comprehensive global strategies.  Bill has extensive experience with constitutional challenges to state and federal statutes and caselaw, including punitive damages and statutory penalties, and he works regularly with inside- and outside co-counsel to develop innovative, cutting-edge trial and appellate strategies to address such issues.  He has played a key role in a number of the firm’s most high-profile transnational, mass tort and product liability, and environmental matters.  Bill has been recognized as a Leading Partner by The Legal 500 US, named one of Lawdragon’s 500 Leading Global Litigators, and has been recognized in The Best Lawyers in America® since 2023 for his Appellate practice.  

• Bill is one of the principal lawyers representing Chevron Corporation in the large number of climate change actions that state and municipal governments have filed around the country pursuant to various state laws, alleging claims for public and private nuisance, product liability, and deceptive sales—attempting thereby to shift liability for national and international energy policy choices onto energy producers. To date, Chevron has prevailed in motions to dismiss in every court to reach the merits.  See, e.g., City of New York v. Chevron Corp., 993 F.3d 81,85 (2d Cir. 2021) (“The question before us is whether municipalities may utilize state tort law to hold multinational oil companies liable for the damages caused by global greenhouse gas emissions.  Given the nature of the harm and the existence of a complex web of federal and international environmental law regulating such emissions, we hold that the answer is “no.”).
• Bill represents Chevron Corporation in its multifaceted defense against purported environmental claims emanating from Ecuador, in which U.S. and Ecuadorian lawyers obtained a purported $18 billion judgment from an Ecuadorian court.  Among other things, Bill spearheaded the extensive briefing in Chevron’s RICO case in the Southern District of New York, in which the company successfully sued the U.S. and Ecuadorian lawyers and other agents for racketeering and fraud. In its 485-page opinion, the court described the case as “extraordinary” and “includ[ing] things that normally come only out of Hollywood,” such as “coded emails,” “payments out of a secret account,” videotaped evidence of crimes in progress, and blockbuster evidence that the defendants “wrote the [Ecuadorian] court’s Judgment themselves and promised $500,000 to the Ecuadorian judge to rule in their favor and sign their judgment.”  The New York Times described the result as a “major victory,” and the Washington Post called it “resounding.”  A unanimous Second Circuit Court of Appeals affirmed, noting that “[t]he record . . . reveals a parade of corrupt actions.” Bill continues to advise Chevron on a range of issues flowing from this high-stakes, complex matter and in related foreign enforcement and international arbitration matters.
• Bill regularly works with a broad variety of companies on strategies to assess and limit their product liability exposure, including in the on-line marketplace space.  Bill has deep experience developing and marshaling constitutional challenges to state-law regimes such as those governing punitive damages and their related underlying liability standards, especially in the product liability context. In this capacity, he works with companies to formulate both immediate-need and long-term trial and appellate strategies, briefing related motions and appeals in numerous jurisdictions around the country and acting as national appellate advisor to trial teams at all stages of the proceeding.  He played a principal role on behalf of Ford Motor Company in persuading the United States Supreme Court to vacate what had been the largest personal injury award ever affirmed in U.S. history—and on remand convinced the court of appeal to cut the award by over 90%—as well as convincing the California Supreme Court to reject the “aggregate profit disgorgement” theory of punitive damages.
• Bill has long played a leading role in defending Dole Food Company, Inc. in its national and international mass tort/product liability litigation involving the nematicide DBCP, brought by thousands of plaintiffs from Nicaragua, Costa Rica, Ecuador, Panama, Guatemala, Honduras, Panama, and the Ivory Coast.  Cases currently are pending in Hawaii and Delaware. He was a key member of the team that successfully represented Dole in both the district court and Eleventh Circuit in the Osorio v. Dole action filed in the Southern District of Florida, where plaintiffs sought to enforce a bellwether Nicaraguan judgment totaling approximately $100 million.  Bill was instrumental in obtaining the dismissal of three DBCP cases pending in the Los Angeles Superior Court as a terminating sanction for plaintiffs’ and their counsel’s fraud on the court in the widely noted Tellez, Mejia, and Rivera cases, and successfully defended the trial court decisions on appeal.
• In both the transnational and domestic settings, Bill has led numerous civil cases brought pursuant to the Racketeer & Corrupt Organizations Act (RICO), representing both civil RICO plaintiffs and defendants in a variety of industry contexts.  He has written and spoken frequently on RICO-related topics. Representative RICO matters include, in addition to Chevron’s lawsuit against the lawyers suing it in Ecuador, defending automaker Aston Martin (Fisker v. Aston Martin Lagonda, C.D. Cal. 2015) (voluntarily dismissed by Fisker, with no settlement); defending Chevron U.S.A. (Committee to Protect Our Agricultural Water v. Chevron, E.D. Cal. 2016) (court granted motion to dismiss; plaintiff dismissed rather than try to amend complaint); defending nursing home owners and officers (Kan-di-Ki v. Paulson, C.D. Cal. 2017) (motion to dismiss granted; affirmed on appeal); defending Lynn Tilton and Patriarch Partners Zohar CDO 2003-1 Ltd. et al. v. Patriarch Partners LLC et al.(S.D.N.Y. 2017) (motion to dismiss granted based on securities fraud bar of 18 U.S.C. §1964(c)).
• Bill also played a key role in Perez v. Dole Food Company, Inc., successfully defeating hundreds of false claims that Dole Food Company funded and directed the activities of AUC paramilitaries in the banana-growing regions of Colombia and was responsible for  hundreds of deaths in connection with Colombia’s internal conflict between warring paramilitaries and guerrillas in that region.  Plaintiffs voluntarily dismissed their claims with prejudice after Gibson Dunn uncovered evidence of improper interactions between plaintiffs’ counsel and jailed paramilitary witnesses.

Bill served as a judicial clerk to the Honorable Robert J. Kelleher in the U.S. District Court for the Central District of California.  He received his law degree from the University of California, Los Angeles, School of Law.  He earned a Ph.D. degree and an M.A. degree from the University of Chicago, and an A.B. degree from Princeton University, all in the field of political science.  At the University of Chicago he was a John M. Olin Fellow at the Center for Inquiry Into the Theory and Practice of Democracy.  For his dissertation on the political theory of Alexis de Tocqueville he conducted research in Paris.  He is fluent in French and conversant in Spanish.

Bill is admitted to practice before the Supreme Court of the United States, California Supreme Court, Second Circuit Court of Appeals, Third Circuit Court of Appeals, Fourth Circuit Court of Appeals, Fifth Circuit Court of Appeals, Sixth Circuit Court of Appeals, Ninth Circuit Court of Appeals, Tenth Circuit Court of Appeals, the Eleventh Circuit Court of Appeals, and the United States District Courts for the Central, Northern, Eastern, and Southern Districts of California.

Andrew Townsell is an associate in the New York office of Gibson Dunn and is a member of the firm’s Business Restructuring and Reorganization Practice Group. His practice focuses on corporate restructurings, distressed financing, liability management transactions, and other special situation transactions in acquisitions, out-of-court restructurings, and Chapter 11 cases.

His representative matters include:*

• Jervois Global Limited and its affiliates, an Australia-headquartered global supplier of advanced manufactured cobalt products with $195.5 million in funded debt, in their Chapter 11 cases in the U.S. Bankruptcy Court for the Southern District of Texas, which effectuated a recapitalization and take-private transaction by the company’s secured lenders.
• Eiger Biopharmaceuticals, Inc., a Palo Alto, California-based biopharmaceutical company that developed treatments for rare metabolic diseases, in its Chapter 11 cases in the U.S. Bankruptcy Court for the Northern District of Texas. The case involved three successful asset sales and the negotiation of a consensual plan of liquidation, resulting in the company’s prepetition secured lender and unsecured creditors being paid in full and distributions being made to equity holders.
• Casa Systems, Inc. and certain of its affiliates, a telecommunications hardware and software company, in their Chapter 11 cases in the U.S. Bankruptcy Court for the District of Delaware.

• West Marine, Inc. and its affiliates, the nation’s leading omnichannel provider in the marine aftermarket, in multiple transactions, including a comprehensive out-of-court restructuring of its existing capital structure supported by 100 percent of the Company’s existing lenders and its equity sponsor. The comprehensive transaction delevered the Company’s funded indebtedness by more than $500 million, provided the Company access to $125 million of new money term loan financing, and left trade claims unimpaired.
• Learfield Communications, LLC and its affiliates, a leading media and technology company in the college sports market, in a nearly $1 billion out-of-court restructuring with unanimous support from Learfield’s existing lenders and equity sponsors. The transactions substantially delevered Learfield’s balance sheet and provided access to significant new money equity investments, strengthening Learfield’s financial and liquidity positions.
• Genesis Care Pty Ltd and its affiliates, one of the world’s largest integrated oncology organizations and the world’s largest provider of radiotherapy, operating more than 400 cancer centers in the U.S., Australia, Spain, and the UK (which treated more than 450,000 patients annually), in their Chapter 11 cases in the U.S. Bankruptcy Court for the Southern District of Texas.  As of its Chapter 11 filing, GenesisCare’s funded debt totaled approximately $1.7 billion, including approximately $1.55 billion in secured term loan indebtedness. GenesisCare commenced its Chapter 11 cases to obtain access to debtor-in-possession financing, to conduct a marketing and sale process for its U.S. assets, and to restructure its financial obligations.
• Avaya Holdings Corp. and its affiliates, a global leader in solutions to enhance and simplify communications and collaboration, in their prepackaged Chapter 11 cases in the U.S. Bankruptcy Court for the Southern District of Texas. With overwhelming consensus from Avaya’s secured lenders and the support of its other key stakeholders, Avaya confirmed its prepackaged plan of reorganization just over a month after it commenced its Chapter 11 cases. The confirmed prepackaged plan reduced Avaya’s total debt by more than 75%, from approximately $3.4 billion to approximately $810 million, substantially increased Avaya’s liquidity position to approximately $650 million, decreased its net leverage to less than 1x, and provided substantial financial flexibility to accelerate Avaya’s investment in its innovative cloud-based communications portfolio. Avaya emerged from Chapter 11 protection as a privately held company approximately five weeks after the bankruptcy court confirmed Avaya’s prepackaged plan.
• Carestream Health, Inc. and its debtor affiliates, a Rochester, New York based global provider of medical imaging systems and non-destructive testing products, in their prepackaged Chapter 11 cases filed in the U.S. Bankruptcy Court for the District of Delaware. Carestream had more than $1.3 billion of prepetition funded debt obligations. Prior to commencing the Chapter 11 cases, Carestream entered into a restructuring support agreement with a majority of its secured creditors to implement the comprehensive restructuring, eliminate approximately $470 million of funded debt obligations, and provide the Company with new liquidity through an $85 million exit facility and $75 million equity rights offering.
• Service King Paint & Body LLC and certain of its affiliates, the third largest operator of auto body collision repair facilities in the U.S. (operating over 300 facilities across 24 states and Washington D.C.), in an out-of-court restructuring transaction involving the raise of $200 million in new capital, reduction of $500 million in net indebtedness, and extension of remaining existing funded debt maturities. The transaction was supported by substantially all of Service King’s funded debtholders in addition to the company’s equity sponsors.
• Envision Healthcare Corporation, a leading provider of physician staffing services and operator of ambulatory surgical centers, in first-of-their kind liability management transactions. The transactions injected $1.1 billion of new money to Envision’s balance sheet and de-leveraged more than $1.9 billion of secured and unsecured debt obligations.
• Premiere Global Services, Inc. and its affiliates and subsidiaries in connection with an out-of-court restructuring by which PGi’s first lien lenders consensually foreclosed upon and sold the equity of Premiere Global Services, Inc. to a third-party buyer. The transaction resulted in mutual releases between the Company’s’ first lien lenders and the Company and related parties and an incremental financing commitment from the Company’s first lien lenders.
• A consortium of bidders led by Flynn Restaurant Group LP, the largest restaurant franchisee in the United States, in their stalking horse bid to purchase certain assets of NPC International, Inc. and its debtor affiliates through a Chapter 11 sale under section 363 of the U.S. Bankruptcy Code. NPC, which operated more than 1,300 Pizza Hut and Wendy’s restaurants across the United States, filed voluntary Chapter 11 cases in the U.S. Bankruptcy Court for the Southern District of Texas in July 2020. Under the terms of the asset purchase agreement, which was approved by the Court in January 2021, the Flynn consortium acquired over 925 of NPC’s Pizza Hut restaurants, approximately half of NPC’s 393 Wendy’s locations, and substantially all of NPC’s shared services assets for $552.55 million.
• Selecta Group B.V in its Chapter 15 proceeding filed in the Southern District of Texas, part of a comprehensive restructuring strategy to deleverage Selecta’s balance sheet, increase liquidity, extend maturity dates on its revolver and its 3 tranches of senior secured notes, and to change the governing law for its funded debt obligations from New York to UK law. The overall restructuring involved out-of-court arrangements with the revolving credit facility lenders and liquidity facility lenders, a new equity investment by the private equity owner, a formal Scheme of Arrangement in the UK, and a US Chapter 15 proceeding to implement the foreign proceeding in the United States.
• Chesapeake Energy Corporation and 40 of its subsidiaries, a premier oil and natural gas exploration and production company with a high-quality, unconventional oil and natural gas asset portfolio, in their Chapter 11 cases in the U.S. Bankruptcy Court for the Southern District of Texas. Chesapeake and its debtor-affiliates had more than $9 billion of funded debt obligations as of the commencement of their Chapter 11 cases. Prior to commencing the Chapter 11 cases, Chesapeake obtained commitments from certain of its secured creditors for over $4 billion of new capital, including a $925 million new money debtor-in-possession financing facility, a $600 million fully backstopped rights offering, and $2.5 billion of exit facilities as part of a comprehensive restructuring support agreement that would eliminate approximately $7 billion of Chesapeake’s funded debt obligations.
• McDermott International, Inc. and 225 of its subsidiaries and affiliates (including 107 foreign domiciled entities) a premier, global upstream and downstream engineering, procurement, construction, and installation company that employs over 42,000 individuals across 54 countries and six continents, in their prepackaged Chapter 11 cases in the U.S. Bankruptcy Court of the Southern District of Texas. McDermott’s prepackaged Chapter 11 cases were confirmed in less than 60 days and contemplated a transaction that re-equitized the company, deleveraged over $4 billion of funded debt, preserved an unprecedented $2.4 billion in prepetition letters of credit, left trade claims unimpaired, and included a sale of McDermott’s Lummus technology business for $2.725 billion.
• Vanguard Natural Resources Inc. and its affiliates, an independent exploration and production company focused on the production and development of oil and natural gas properties in the United States with operations in the Gulf Coast, Permian, and Anadarko Basins, in their Chapter 11 cases in the U.S. Bankruptcy Court of the Southern District of Texas. Vanguard had approximately $850 million in debt at the time of filing and obtained a commitment for a $130 million debtor-in-possession financing facility, which included $65 million in new money.
• iHeartMedia, Inc. and certain subsidiaries, one of the world’s leading global multi-platform media, entertainment, and data companies, in their Chapter 11 restructuring. iHeart is the largest radio broadcaster in the United States and specializes in radio, digital, outdoor, mobile, social, live events, on-demand entertainment and information services for local and national communities. The Company had consolidated debts of over $20 billion, and the Chapter 11 cases restructured over $16 billion of that debt.
