Steadfast defense for individuals and corporations in even the most high-profile and challenging government investigations, criminal prosecutions, and other regulatory enforcement actions.

Our team of former Department of Justice lawyers and seasoned litigators brings decades of experience to help clients navigate the complexities of government enforcement actions, internal investigations, and high stakes litigation. We provide strategic counsel and vigorous advocacy to corporations, executives, healthcare providers, and other professionals facing regulatory scrutiny, criminal charges, or civil liability under civil enforcement statutes such as the False Claims Act. 

Building on our experience inside the government and as outside counsel for businesses and individuals, Parker Hudson has credibility with federal and state agencies throughout the country.

We leverage that credibility to conduct measured and efficient investigations, provide guidance through government enforcement actions, mount strategic defenses, and work with clients to help minimize any collateral harm that may come with a government investigation or enforcement action.

  • Appointed by the United States District Court, Northern District of Georgia, to defend a former employee of an automotive dealership against federal criminal conspiracy and theft charges. After the close of the government's case during a week-long jury trial, successfully argued that the lead count in the indictment should be dismissed because the government failed to present sufficient evidence to sustain a conviction. After presenting defense case, the jury found client not guilty on the remaining three counts, thereby completely exonerating the client. All of the other defendants in the case either pled guilty or were convicted at trial.
  • Defended former company president of a major food processing company who received a "target" letter from the government in connection with a nationally publicized investigation into possible criminal immigration offenses. Through a series of presentations, convinced the government to rescind the target letter and bestow derivative and use immunity upon client.
  • Represented a hospital in significant litigation against a former physician employee and executive. The case involves several claims and counterclaims relating to the physician's departure from employment with our client and his decision to work for a competitor hospital in violation of his non-competition covenant, as well as disputes relating to compensation issues. After extensive discovery, defeated the physician's motion for summary judgment as to the alleged unenforceability of his non-competition covenant and convinced the Court to grant summary judgment for the hospital on physician’s tort claims. The case is pending before the Georgia Court of Appeals.
  • Represented the interests of a hospital system that was the victim of a complex investment fraud scheme. Worked with attorneys from the United States Securities and Exchange Commission and the United States Attorney's Office in civil and criminal enforcement actions brought against investment manager and investment consultant and prosecuted a private civil action directly against investment consultant.
  • Represented the interests of a co-owner of a hedge fund in a criminal insider trading investigation. Convinced the Department of Justice not to indict our client even though the Department of Justice indicted the other owner of the hedge fund.
  • Represented a law firm in a government investigation and related civil proceedings involving allegations that deceased managing partner stole millions of dollars of client trust funds over many years.
  • Litigated lengthy evidentiary hearing in habeas case filed by individual sentenced to 30 years in prison for a large fraud scheme and argued case on appeal, which resulted in a published Eleventh Circuit decision.*
