Areas of Practice
Antitrust
Antitrust enforcement today is defined by complexity— multiple jurisdictions, shifting priorities, and various theories of harm. Clients turn to Lindsay Cooley Law for strategic clarity across that landscape. We bridge the gap between enforcement theory and practical outcomes, helping clients evaluate merger risk, structure remedies, and anticipate multistate coordination before it takes shape. Advice is grounded in firsthand understanding of how Attorneys General and federal agencies approach competition policy and evidence. Whether transactional, developing advocacy strategies, or responding to investigative demands, we offer practical and clear commercially attuned guidance.
The goal is not simply to predict enforcement, but to shape how it perceives the facts—turning insight into advantage.
Litigation Advice
Navigating complex litigation requires knowledgeable “words out loud in court” trial experience, not just a famous name and some speeches.
Lindsay Cooley Law provides strategic advisory support to law firms and litigation teams confronting those issues. We integrate enforcement context into motion practice, discovery strategy, and remedy design, ensuring arguments resonate with regulators and courts alike. Clients benefit from concise, actionable analysis that connects economic theory, legal precedent, and agency behavior. Engagements are collaborative and confidential, designed to strengthen existing trial strategy rather than replace it. The result is litigation advice that is both realistic and forward-looking—focused on credibility, coherence, and long-term positioning.
Attorneys General Intelligence
Understanding the Attorneys General is essential to managing antitrust risk. Lindsay Cooley Law monitors multistate priorities, leadership transitions, and coordination trends to help clients anticipate enforcement before it materializes. We provide tailored intelligence on how state coalitions form, how priorities evolve, and how federal–state relationships shape outcomes. This perspective informs transaction planning, compliance design, and negotiation strategy. Clients gain not only early warning of potential investigations, but a framework for constructive engagement with enforcers. In an environment where state action can redefine national policy, informed insight is a competitive advantage.
A single courageous state may, if its citizens choose, serve as a laboratory, and try novel social and economic experiments without risk to the rest of the country.
- Justice Louis Brandeis, New State Ice v. Leibmann, 285 US 262 (1932)
