Discovery is the engine behind successful antitrust cases. Whether you're investigating price-fixing, bid rigging, or abuse of market dominance, strategic discovery reveals the patterns and communications that shape competitive harm.

Discovery plays a pivotal role in antitrust litigation by enabling plaintiffs and regulators to uncover hidden agreements, market manipulation, or exclusionary practices. Because antitrust claims often involve secret conduct—like horizontal conspiracies or unilateral exclusion—discovery becomes the primary tool for surfacing evidence of unlawful competition.

These cases are highly fact-intensive. Proving violations of the Sherman Act, Clayton Act, or state equivalents requires digging deep into business records, emails, market data, and internal analyses. Discovery requests must be crafted with precision to identify key actors, timelines, and economic indicators relevant to alleged anticompetitive conduct.

❗The stakes are significant. Inadequate discovery can allow coordinated conduct to remain concealed, while overbroad or unfocused requests can result in costly delays, motion practice, and judicial pushback.

✅ When discovery is targeted and strategic, it becomes the gateway to revealing unlawful market behaviors—and securing justice for impacted parties.

🎯 Why This Guide Matters

Antitrust discovery demands a deep understanding of both legal standards and economic frameworks. Legal teams must uncover direct and circumstantial evidence that may be buried in millions of documents and complex data sets.

This article equips you to:
• ✅ Draft discovery requests that target collusive or monopolistic practices
• ✅ Uncover economic and market evidence essential for proving harm
• ✅ Navigate confidentiality concerns tied to business strategy and pricing
• ✅ Use discovery to expose unlawful restraints on trade

1. The Foundations of Antitrust Discovery

Antitrust discovery focuses on three primary categories of violations:

• Horizontal restraints (e.g., price-fixing, bid-rigging, market allocation)

• Vertical restraints (e.g., exclusive dealing, resale price maintenance)

• Monopolization or attempted monopolization under Section 2 of the Sherman Act

Discovery requests are vital to establishing critical elements such as:

• Agreements or coordinated conduct between competitors

• Market definitions and barriers to entry

• Pricing strategies, internal economic modeling, and profit margins

• Communications that show intent to exclude or fix prices

💡 Tip: Don’t rely solely on requests for production. Combine RFPs with interrogatories and requests for admission to extract a complete narrative.

2. Targeting Documents that Reveal Anticompetitive Intent

Antitrust violations often live in internal communications and economic records. Effective RFPs should seek:

• Board meeting minutes and strategy decks discussing competitors

• Pricing and discount policies, especially if “most favored nation” clauses exist

• Communications with competitors, trade associations, or industry groups

• Documents analyzing market share, customer allocation, or new entrants

• Emails and chat logs referencing competitor pricing or exclusion strategies

📋 Practice Tip: Use date ranges tied to known market shifts or alleged conduct to streamline production and avoid unnecessary disputes.

3. Leveraging Economic Data for Competitive Analysis

Economic evidence can make or break an antitrust case. Seek discovery of:

• Sales data by region, product line, or customer category

• Pricing changes following key competitor moves

• Cost structures and margins relevant to predatory pricing claims

• Internal market share reports or forecasts

• Contracts and rebate agreements that may restrict competition

🧠 Strategy Insight: Use economist input when drafting discovery. Their models often dictate what data is essential for proving anticompetitive effects.

4. Identifying Key Custodians and Collaborators

Success in antitrust discovery depends on identifying the right sources of information. Be sure to include:

• Executives involved in pricing, sales, and market strategy

• In-house economists or strategic planning teams

• Representatives attending trade association meetings

• External consultants or PR firms assisting with competitive positioning

• IT custodians managing internal communications platforms

🎯 Effective RFPs should name specific individuals or roles and include metadata requests to capture timelines and communication patterns.

5. Navigating Confidentiality and Trade Secret Concerns

Antitrust discovery frequently involves sensitive business intelligence. To safeguard it:

• Seek or agree to protective orders that shield pricing, strategy, and forecasting data

• Use “attorney’s eyes only” designations for highly sensitive content

• Redact customer-identifying data when needed but push for transparency where critical

• Set ESI protocols that restrict how competitive data is accessed and stored

💡 Best Practice: Coordinate with opposing counsel early to avoid delays and motion practice over confidentiality disputes.

6. Proactive Use of RFAs and Interrogatories

While documents and data are foundational in antitrust discovery, interrogatories and requests for admission (RFAs) serve a different but equally strategic function: pinning down the other side’s story early, precisely, and under oath. They are powerful tools for obtaining admissions, clarifying factual ambiguities, and forcing parties to commit to positions that can be tested later in depositions or trial.

These tools are especially valuable in antitrust litigation, where parties often resist disclosing collusive intent and market motivations. Used thoughtfully, interrogatories and RFAs can surface admissions that documents alone may not clearly establish.

✅ Examples of high-impact RFAs and interrogatories in antitrust cases include:
• Asking the defendant to admit or deny direct communications with named competitors, including emails, texts, or meetings related to pricing, bidding, or territorial strategy
• Requiring explanations for price changes, rebate structures, or exclusive supply contracts—especially when those coincide with alleged anticompetitive conduct
• Probing the company’s awareness of competitors’ conduct, including how pricing decisions were influenced by external market signals
• Seeking the identification of employees involved in decisions regarding customer allocation, distribution limitations, or membership in industry groups

📋 Practice Insight: Interrogatories are especially useful when trying to understand the rationale behind non-public business decisions. For instance, if the plaintiff alleges price coordination, interrogatories can demand a breakdown of each pricing decision, who approved it, and how it was justified internally.

🧠 Strategic Use Case:
Start with RFAs to test the waters—get the opposing party on record about whether key communications or meetings occurred. Then follow up with interrogatories to dig deeper into the purpose and content of those interactions. If discrepancies emerge, use depositions to confront and undermine their credibility.

🔍 Example Workflow:

1. RFA: Admit or deny that you communicated with XYZ Corp. regarding pricing in Q1 2023.

2. Interrogatory: If denied, describe all pricing discussions your company had in Q1 2023 involving the widget market, identifying participants and documentation.

3. Deposition: Use the interrogatory answer and email metadata to question inconsistencies and challenge vague justifications.

📌 Bonus Tip: Combine RFAs with Rule 30(b)(6) depositions to box in corporate representatives. Once admissions are made, you can press for detailed factual testimony that aligns (or conflicts) with earlier responses.

7. Case Examples: Discovery That Uncovered Antitrust Misconduct

🔍 Case 1 – Email Evidence of Bid Rigging
Internal emails between rival contractors revealed coordinated bids to inflate government contract pricing—core evidence that led to treble damages under the Sherman Act.

🔍 Case 2 – Exclusive Dealing Strategy Exposed
Discovery revealed that a dominant supplier used rebates to foreclose competitors from access to distribution—evidence that supported a successful Section 2 claim.

🔍 Case 3 – Pricing Model Discrepancies
Sales data showed below-cost pricing in targeted markets, helping prove predatory intent. Expert economic analysis was made possible by well-scoped discovery.

Practical Tips for Antitrust Discovery

• 🎯 Align requests with legal theories: conspiracy, exclusion, or monopoly
• 📋 Use ESI and search terms strategically to surface collusion evidence
• 🤝 Be aggressive in meet-and-confer but open to phased production
• 🔍 Involve economists early to define relevant market and data needs
• 🧠 Know your judge’s history on antitrust scope and confidentiality issues

FAQs

Q1: What types of documents are most valuable in antitrust discovery?
Internal communications, pricing models, and economic strategy documents are often the most revealing.

Q2: How do I prove a conspiracy without a written agreement?
Use circumstantial evidence such as parallel behavior, inter-competitor communications, and industry association records.

Q3: Can I request competitor communications directly?
Yes—especially if the competitor is a party or if the communications relate to the conduct at issue.

Q4: How do I protect trade secrets during antitrust discovery?
Negotiate protective orders and limit access to essential parties, such as outside counsel or designated experts.
