Mark Filip - Kirkland & Ellis LLP

Within: Corporate investigations and white-collar criminal defense

Excellent in every respect’, the team at Kirkland & Ellis LLP have recently welcomed back a number of key partners: In Washington DC, William Barr re-joined after serving as US Attorney General, Neil Eggleston re-joined after serving as White House Counsel to President Barack Obama, and Erica Williams re-joined from an associate counsel position in the Obama White House. The Chicago-based Mark Filip leads the team; he acted alongside Andrew Genser in New York and Viet Dinh in Washington DC for a Chinese real estate billionaire in a criminal case alleging conspiracy to violate the FCPA. The practice is also representing Allergan in various state and federal investigations, congressional inquiries and civil suits related to its sale and marketing of opioid painkillers. It also acted for General Motors in the high-profile ignition switch litigation and related government investigations, leading to a corporate criminal resolution with the DOJ.

Financial services litigation

Within: Financial services litigation

Leveraging its heavyweight general commercial litigation reputation, and also calling upon the expertise of practitioners within the firm’s government and internal investigations team, Kirkland & Ellis LLP provides a ‘top-notch’ service to clients that include Hercules Capital, Deloitte Tax and Citigroup Global Markets as a result of its ‘excellent understanding of the law and ability to create innovative arguments and develop case strategy’. The firm’s added credibility on the appellate front following the recent absorption of Bancroft PLLC has also led to some notable financial services-related mandates. Paul Clement, the former US solicitor general and previously a partner at legacy firm Bancroft, secured a notable victory on behalf of HSBC when the appellate court blocked the release of the bank’s money laundering report which had been prepared under a deferred prosecution agreement (DPA). Other recommended partners include Mark Filip, Robert Kopecky and Neil Eggleston, who recently returned to the firm following a tenure as White House counsel to President Obama. Former director of enforcement at the SEC Robert Khuzami left the firm in January 2018 to take up the position of deputy US attorney for the Southern District of New York.

General commercial disputes

Within: General commercial disputes

Among the best for highly complex and potentially "bet the company" legal issues’, Kirkland & Ellis LLP’s litigation team is ‘client-oriented, creative and smart’. With 500 attorneys in the litigation practice firmwide, it is one of the largest groups in the market. Of particular note is the team’s broad experience in state and federal courts - including at appellate level - and in arbitration proceedings. A team that includes Mark Filip, Donna Welch, Leslie Smith and Jennifer Levy is representing Allergan in the closely watched opioids investigations, which span state and federal governmental investigations, congressional inquiries and civil lawsuits. Elsewhere, James Hurst and Andrew Kassof secured a victory for Abbott Laboratories in a False Claims Act (FCA) jury trial in the Northern District of Texas, which was affirmed by the Fifth Circuit in May 2017. Richard Godfrey is a ‘brilliant class action lawyer’. Andrew McGaan and Washington DC-based Eugene Assaf are also recommended. Above-named partners are based in Chicago unless otherwise stated. In April 2018, star litigator Sandra Goldstein joined from Cravath, Swaine & Moore LLP.

The team at Kirkland & Ellis LLP is ‘extremely knowledgeable, has great judgment and is a pleasure to work with’. The firm has recognized strengths in investigation and enforcement actions, accountant liability matters and securities class actions. Mark Filip, who works from Chicago and Washington DC, leads the government enforcement and defense practice. He recently advised Rio Tinto on a securities fraud case arising from a fall in its stock price following the disclosure of a corruption investigation involving its operations in the Simandou iron mine. Matthew Solum represented private equity firm Advent International in a class action arising from Party City Holdco Inc’s IPO, in which plaintiffs alleged the company failed to disclose the impact of a decline in Frozen merchandise sales. Chicago-based Joshua Rabinovitz and John Hartmann acted for FTD Companies in multiple class actions regarding accusations of making false and misleading statements in connection with an acquisition. DC-based litigator Neil Eggleston, who was White House Counsel to President Obama until 2017, is recommended. In April 2018, top-flight litigator Sandra Goldstein joined from Cravath, Swaine & Moore LLP.
