We have a reputation for defending, prosecuting, and coordinating some of the largest, most complex cases ever filed in courts, before arbitration panels, or in private mediations.

Consequently, we have a long record of successfully resolving these proceedings on behalf of clients across industries, including retail and consumer products, energy, chemicals, media and entertainment, healthcare and life sciences, heavy manufacturing, insurance, technology, and financial services. Likewise, our experience covers a broad range of substantive areas of law, including fraud, bankruptcy, media and entertainment, trade secrets and restrictive covenants, unfair and deceptive trade practices, RICO, insurance and reinsurance, breach of contract, consumer protection, product liability, and antitrust, among many others.

The practice's comprehensive offerings are supported by a number of foundational capabilities:

Trial Ready Approach

In today’s risk-averse legal environment, there are few firms that can match Weil’s trial resume and breadth of practice. Drawing on the robust experience of leading trial lawyers across all of our practices and offices, our litigation attorneys possess the tools to take any matter to trial – and win. We seek always to find the most cost-effective, efficient and judicious solution from a business standpoint for our clients – but our clients and our adversaries always know we are prepared to advocate in the courtroom.

Class Action and Multi-District Litigation Experience

Weil has an excellent track record in defending complex, multi-plaintiff actions, including proceedings before the Judicial Panel on Multi-District Litigation (MDL) and under various state multi-district litigation statutes, as well as class and collective actions in state and federal courts around the United States. From multi-hundred-plaintiff MDLs regarding healthcare reimbursement rates to significant class actions challenging immunity under the Communications Decency Act, Weil’s Complex Commercial Litigators have extensive experience litigating high-value claims, cases of first impression and other significant issues in these contexts for clients across the industry spectrum.  Read more
