Eimer Stahl defends companies, boards, and individuals in government investigations and white collar criminal matters. Our clients face inquiries and enforcement actions brought by the U.S. Department of Justice, the SEC, other federal regulators, state Attorneys General, and state and local prosecutors, including matters involving alleged consumer protection, technology, financial services, privacy, healthcare, and other systemic misconduct claims.
Government investigations and white collar matters often turn on inflection points that occur before any public filing — the opening of an inquiry, the issuance of a grand jury subpoena or civil investigative demand, charging decisions, and parallel-proceeding coordination. At those stages, we engage directly with enforcement authorities through targeted presentations, disciplined fact development, and coordinated advocacy across parallel proceedings, including managing privilege and factual positions to avoid cross‑exposure.
Joseph Tartakovsky and Bradley Tucker, both former Assistant United States Attorneys, bring experience in investigating, charging, and trying complex federal criminal cases; four of the firm's lawyers — Ryan Walsh, Amy Miller, Tartakovsky, and James Barrett — previously served in senior roles within the Solicitor General offices of state Attorneys General; and Nathaniel Wackman previously served as General Counsel to the City of Chicago Office of Inspector General, overseeing legal strategy for criminal and administrative investigations.
Because we have led and resolved investigations from inside government, we know when enforcement authorities are testing theories, building cases, or making charging decisions — and we act at those moments. Our approach emphasizes early engagement with prosecutors, methodical evidence development, and careful management of privilege across parallel civil, regulatory, and criminal proceedings, alongside a realistic assessment of charging risk and sentencing exposure.
We also advise boards of directors, committees, and senior management on sensitive internal investigations, structuring investigations with a clear view of the questions prosecutors and regulators will ask, while accounting for parallel civil, regulatory, and reputational considerations.
The practice covers federal grand jury matters and trials, internal investigations, parallel civil-regulatory-criminal proceedings, and state attorney general enforcement.
