JUSTICE JAGHER LONDON & MILLEN
Antitrust
Challenging Conduct That Undermines Competition.
Competition is the foundation of a fair marketplace. When it breaks down, the consequences are widespread.
For more than four decades, our attorneys have represented businesses and consumers harmed by anticompetitive conduct. From nationwide price-fixing conspiracies to dominant firms abusing market power, JJLM focuses on cases where unlawful behavior distorts markets at scale.
We combine deep litigation experience with a clear understanding of how modern markets operate to deliver results that not only compensate those harmed but restore competitive balance.

A Principled Approach to Antitrust Enforcement.
Our approach is grounded in three core pillars: Integrity. Innovation. Impact.
Protecting the Foundations of Competition.
Antitrust laws exist to ensure that competition, not collusion, drives the marketplace. We serve as a critical check on anticompetitive conduct, from straightforward price-fixing agreements to complex, multi-participant coordination.
Our work focuses on uncovering and challenging conduct that distorts markets, including price-fixing, bid-rigging, market allocation, monopolization, and exclusionary practices.
Addressing Modern Market Realities.
Antitrust violations are often self-concealing and increasingly sophisticated. Today’s cases arise in complex, interconnected markets shaped by technology, data, and global supply chains.
We approach these matters with a modern, strategic lens — combining legal insight and creative litigation strategies with economic analysis to identify patterns of unlawful conduct that are designed to remain hidden.
Our work spans digital platforms, supply chains, financial markets, and commodity products — including emerging issues such as algorithmic price coordination and data-driven market power.
Delivering Results That Shift the Balance.
Antitrust litigation is about more than recovery — it is about restoring the integrity of the marketplace.
JJLM attorneys have helped secure billions of dollars in recoveries and have served in leadership roles in some of the most significant antitrust cases in the country.
Our focus is on outcomes that deliver meaningful compensation, deter unlawful conduct, and drive lasting change in how markets operate.
Modern Markets
Antitrust issues arise in dynamic and evolving markets. We regularly handle matters involving digital platforms, data-driven ecosystems, supply chains, and financial markets - where traditional forms of coordination and market power take new and often less visible forms.
We ground our work in understanding how these markets actually function and where they break down.
Our Approach
We build every case with the expectation that it may proceed to trial. From investigation through discovery, class certification, and trial, we bring rigorous analysis, practical judgment, and innovative litigation strategy to build cases designed to succeed at every stage.
We Level The Playing Field
When companies collude or abuse market power, the consequences are rarely isolated. Entire markets can be affected - raising prices, limiting choice, and excluding competitors.
We bring the experience, resources, and trial-focused strategy necessary to take on complex, high-stakes antitrust cases. Our work is grounded in a clear understanding of how markets function and a commitment to holding powerful actors accountable.
We do not approach these cases as routine litigation. We approach them as matters that shape markets.
Restoring competition is only part of the work. Antitrust enforcement must also deliver recovery to those harmed. Our practice is built to achieve both.
