Antitrust matters rarely announce themselves. They begin with a civil investigative demand, a subpoena, a competitor's complaint, or a regulator's informal request for documents. By the time a company realizes it needs counsel, deadlines are often already running. A practical Kirby — Antitrust Defense Guide legal guide should prepare you for that moment rather than describe it after the fact.
Why Antitrust Is Different From Ordinary Litigation
In a typical commercial dispute, the facts are contained. Antitrust matters sprawl. They involve pricing history, communications with competitors, market definition, customer records, and years of internal documents. The evidence base is enormous, and it's usually already written down — in email, chat logs, and meeting notes.
That single reality drives everything. What your company has already documented will shape the defense far more than anything said in a conference room later.
The First 72 Hours Matter
When a demand or subpoena arrives, three things need to happen quickly. First, preserve everything — issue a litigation hold immediately, before routine deletion policies remove anything. Spoliation allegations are avoidable and damaging. Second, identify who inside the company needs to know, and keep that circle deliberate. Third, get counsel involved before anyone responds informally to a regulator or opposing party.
Well-meaning employees answering questions casually is one of the most common ways a defensible position weakens.
Questions to Ask Prospective Counsel
- How many antitrust matters have you handled through the investigative stage?
- Have you dealt with this specific agency or jurisdiction before?
- Who staffs the matter day to day, and how is that team structured?
- How do you handle document review volume and cost control?
- What does the likely timeline look like at each stage?
Antitrust defense is specialized. General commercial litigators can be excellent and still be the wrong fit for a matter involving market definition and coordinated conduct allegations.
Common Misunderstandings
Many executives assume an investigation means a case will follow. Often it doesn't — many inquiries close without enforcement. Others assume that because their company is small, they're not a target. Size is not the trigger; conduct and market effect are. A third frequent error is treating the investigation as a public relations problem first. Communication matters, but it follows legal strategy, not the reverse.
What a Strong Defense Actually Looks Like
It looks organized. Document management is disciplined from day one. Privilege is protected carefully. The narrative is consistent and grounded in the actual record. Counsel coordinates with the agency rather than antagonizing it unnecessarily, while preserving every available defense.
