About

Provided by Cahill Gordon & Reindel LLP

Cahill has a prominent litigation practice with approximately 150 litigators. Our clients operate in an increasingly complex litigation landscape. We handle matters in highly specialized areas including appeals; securities laws; antitrust and trade regulation; insurance and reinsurance; First Amendment and other constitutional law challenges; copyright, trademark and trade secret disputes; communications; bankruptcy litigation; structured finance; anti-corruption law including FCPA and OFAC; as well as complex commercial disputes involving claims of accounting and legal malpractice, fraud, breach of contract, breach of fiduciary duty and other business disputes. 

We have recently represented public and private multinational companies, insurers, financial institutions and publishing companies, among others, in a variety of complex commercial disputes and in regulatory and enforcement situations. We are also proud to be considered "the litigator's litigator," the firm that a number of the country's largest and most successful law firms have chosen to defend them in high-stakes securities and professional responsibility claims.

Among our litigators are former law clerks at the federal trial and appellate levels, including the Supreme Court of the United States, and lawyers who joined Cahill following distinguished careers in the SEC, DOJ, Department of the Treasury and other federal and state bodies.
