New DOJ-DHS Trade Fraud Task Force Signals Increased Tariff and False Claims Act Enforcement [Alert]

Calli Padilla, Micah Myers, Arthur Fritzinger, and Nicole Sprinzen discuss the new DOJ-DHS Trade Fraud Task Force aims to aggressively enforce import laws and regulations, including collecting tariffs and penalties from importers who attempt to evade them.

As a member in the firm’s White Collar Defense & Investigations practice group, Calli delivers exceptional representation to corporate and individual clients in criminal matters and regulatory and enforcement actions.  Her practice includes advising clients in matters arising under the False Claims Act (FCA), the Foreign Corrupt Practices Act (FCPA), health care fraud, financial services fraud, securities fraud, mail and wire fraud, antitrust violations, and pandemic-related fraud.  She is the co-author of the firm’s Whistleblower Watch, a quarterly publication presenting notable FCA enforcement actions, settlements, and legal trends.     

Calli also devotes a significant portion of her practice to conducting internal investigations.  She has led investigations pertaining to allegations of workplace harassment and hostile work conditions and allegations of harassment and assault in athletic programs and academic institutions.  To that end, Calli frequently advises clients regarding implementation of remedial measures, recommendations, and corporate governance and compliance programs.

Calli also maintains a robust civil practice, representing corporations and individuals in complex commercial and business litigation matters.  She has represented clients in both state and federal courts in a variety of disputes, including breach of contract, common law fraud, antitrust, casualty defense, and catastrophic tort matters, among others. Calli guides her clients through all stages of complex litigation – initial pleadings through discovery, motion practice, mediation, trial, and even appeals. She has tried several cases to verdict or judgment and has secured numerous dismissals, judgments, and favorable settlements for her clients.

Calli also has significant experience advising NCAA coaches and student-athletes on NCAA matters pertaining to eligibility, recruiting, and amateurism. As a former student athlete herself, she has successfully counseled several clients through NCAA enforcement proceedings.

Calli is also a committed firm leader.  She is currently the co-chair of the Women’s Initiative, dedicated to the development and enhancement of professional and personal relationships among female attorneys and clients. She has served as the firm’s hiring partner and, prior to that, chaired the firm’s Associate Committee. Calli remains actively involved in summer associate and lateral recruiting, as well as in the mentoring of junior attorneys. As someone who is committed to serving her community, Calli regularly represents clients on a pro bono basis. She serves on the Eastern District of Pennsylvania’s Attorney Panel for Pro Se Prisoner Civil Rights Cases and does work with the Pennsylvania Innocence Project and the Support Center for Child Advocates.

Prior to joining Cozen O’Connor as an associate, Calli participated in the firm’s Summer Associate Program. Calli received her law degree, cum laude, from the Villanova University School of Law, where she was a managing editor of the Villanova Law Review and the president of the Women’s Law Caucus.  Calli received a degree in politics from Princeton University, where she served as the captain of the women’s varsity softball team
