Antitrust law
Practical advice for companies responding to civil antitrust subpoenas while preserving privilege and avoiding self incrimination.
In civil antitrust investigations, organizations should carefully balance cooperation with subpoenas against safeguarding privilege, privilege protections, and strategic disclosures that minimize self-incrimination while preserving litigation advantages.

When a company receives a civil antitrust subpoena, the initial response sets the tone for subsequent proceedings. The organization should appoint a dedicated internal team, including counsel with antitrust and privilege expertise, to assess the scope of the request, identify potentially privileged materials, and determine reporting lines. Early coordination with outside counsel is essential to ensure that privilege protections shield relevant documents and communications. A thorough record of internal communications about privilege decisions can be critical if a dispute arises about what must be produced. Companies should also map custodians, data systems, and stored information to understand where responsive material resides, including emails, chat threads, collaboration apps, and financial records.
In the first weeks after service, careful scoping is critical. Drafting a privilege log that is precise and complete helps prevent later disputes about what was withheld or produced. Privilege assertions must be based on established legal grounds such as attorney-client privilege, work product, and the common interest doctrine when appropriate. The privilege log should describe documents succinctly without disclosing sensitive legal strategy. Equally important is the decision whether to assert clawback protections under applicable rules for inadvertently produced privileged materials. Firms should implement a consistent process to review, mark, and segregate documents that could be privileged, ensuring compliant handling during production.
Safeguard privilege while meeting legitimate investigative needs.
A robust privilege plan begins with a clear policy on privilege-logging, redaction, and clawback procedures. It should specify who has authority to determine privilege, how to document the rationale, and what categories of materials will be withheld. The plan must address communications among in-house counsel, outside counsel, and executives to preserve confidentiality while allowing the company to respond efficiently. In practice, privilege defenses often hinge on the context of the document and the purpose of the communication. The team should distinguish strategic communications that anticipate litigation from ordinary business discussions. Documentation should reflect that legal advice was sought for the purpose of facilitating a legal defense, not for business as usual decisions.
Beyond privilege, companies must consider self-incrimination risks when responding to fact-finding questions or document requests. Providing information that could be used to infer illegal collusion requires careful navigation. Counsel should assess questions for potential misuse and implement objections where appropriate, citing relevant privilege and disclosure limitations. Where possible, responses should be tailored to factual information that does not reveal strategic deliberations or admission of conduct that could be construed as wrongdoing. In addition, corporate officers should be briefed on the importance of consistent messaging to avoid inadvertent admissions. A well-structured privilege and compliance program helps limit exposure while still satisfying legitimate investigative aims.
Implement staged production and timely negotiations with care.
For custodians and data teams, a defensible data-retention plan supports lawful production without compromising privilege. Data maps identify where communications and documents live, who has access, and how information flows through cloud services and on-site servers. Routine preservation notices should be drafted in collaboration with counsel to clarify that certain materials are protected and not subject to production, except as narrowed by court order or statutory demands. IT teams can assist by implementing workflows that preserve relevant metadata, maintain chain of custody, and facilitate secure transfer of documents to counsel. Clear protocols help prevent accidental disclosure that could undermine privilege or invite sanctions.
When preparing for production, organizations should implement a staged approach to avoid over-disclosure. Initially, produce non-privileged, responsive documents that are not sensitive, followed by a carefully controlled privilege-logged subset. If the request scope is broad, negotiate reasonable limits, focusing on time periods, topics, and custodian pools. Counsel may propose protective orders, sealing, or in-camera review to balance transparency with privilege protection. Throughout this process, maintain open lines of communication with the requesting party to manage expectations and reduce the risk of disputes. Demonstrating cooperation, while preserving privilege, can shorten resolution timelines.
Foster education on privilege, compliance, and risk.
Experience shows that proactive, transparent, but cautious cooperation pays dividends in civil antitrust matters. The company should prepare a concise narrative describing its business practices and how privilege was preserved in the production process. This narrative can aid the court or regulator in understanding the boundaries between permissible disclosures and protected communications. During meetings or correspondence with the subpoenaing party, legal teams should remain consistent in terminology and in claims of privilege. In addition, a documented communications plan helps ensure that business leaders understand what can be shared publicly and what must be kept confidential to protect privilege.
Internal education is a practical pillar of resilience. Regular training for executives, managers, and custodians on privilege, self-incrimination risks, and lawful responses reduces the likelihood of inadvertent disclosures. Training should cover how to identify sensitive communications, when to consult counsel, and how to document decisions properly. A culture that respects privilege reduces the chance of misinterpretation or overreach during production. Importantly, the training should also address the consequences of noncompliance with subpoenas, emphasizing the potential for sanctions, fines, or adverse inference that could complicate the company’s position.
Keep precise chronology and documented rationales.
In parallel with privilege-focused efforts, consider the potential role of compliance controls in the broader program. The company should review internal policies on antitrust compliance, governance, and whistleblower channels to ensure alignment with legal obligations. When responding to subpoenas, reference to these policies can demonstrate a good-faith effort to comply while resisting improper disclosures. Counsel can help craft responses that acknowledge lawful requirements without exposing sensitive strategies or admissions. A cohesive governance framework supports ongoing privilege protection and can reassure regulators that the organization is serious about compliance and ethical conduct.
As the process unfolds, maintain a transparent but careful record of every step taken. Document the dates of service, the scope of requested materials, privilege determinations, and any negotiations or disputes. This chronology is invaluable in case of later proceedings or appeals. A well-maintained record helps demonstrate that the company has acted responsibly, selectively, and with professional legal guidance. It also supports a reasoned defense against claims of discovery abuse or retaliation for pursuing legitimate privilege protections in response to the subpoena.
When issues arise, use formal, timely channels to resolve disputes. If the subpoenaing party challenges a privilege log entry or questions the scope of production, seek a prompt conference with the court or regulator. Propose a protective order, in-camera review, or limitations on the number of custodians to minimize disruption and controversy. Throughout such discussions, rely on clear, written explanations of why particular documents are privileged and why certain questions must remain unanswered or partially answered. Courts often appreciate a disciplined, disciplined approach that prioritizes accuracy and proportionality. A strong argument for privilege protection must be supported by established case law and the specific factual context.
Finally, plan for post-subpoena reflection and improvement. After the matter concludes, conduct a debrief to identify lessons learned about privilege protection, documentation practices, and coordination with outside counsel. Update policies, refine privilege logs, and adjust production workflows to reflect experience. Sharing insights with senior leadership fosters continuous improvement and helps strengthen future responses. A forward-looking posture reduces risk and positions the company to manage civil antitrust inquiries more efficiently. In the end, a disciplined program that protects privilege while fulfilling legitimate investigative obligations supports long-term resilience and lawful corporate conduct.
