White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
Allegations of obstruction of justice place an individual or organization under the full weight of the American justice system. These accusations are not treated as technical violations or procedural missteps; they strike at the heart of the judicial process itself. Prosecutors view obstruction as an attempt to distort truth, influence outcomes, or interfere with lawful investigations—making these cases among the most aggressively pursued at both the federal and state levels.
At The Chapman, Dowling & Mallek, we understand that obstruction allegations often arise in already high-pressure circumstances: federal investigations, grand jury proceedings, criminal prosecutions, or regulatory audits. In many cases, clients never intended to “obstruct” anything at all. Yet routine decisions, misunderstood communications, or poorly timed actions can quickly be reframed by the government as criminal interference. Defending against these claims requires immediate, strategic, and highly experienced federal counsel.
An obstruction of justice defense is not about reflexive denial—it is about dismantling the government’s narrative. Prosecutors must prove that the accused knowingly and corruptly interfered with a qualifying legal or governmental proceeding.

Obstruction cases are treated as priority matters by enforcement authorities.
These cases frequently escalate quickly, with prosecutors adding obstruction charges to increase leverage and sentencing exposure.
Obstruction of justice carries severe criminal and collateral consequences.
Most federal charges fall under 18 U.S. Code Chapter 73:
State obstruction charges range from misdemeanors to serious felonies, often carrying prison sentences, fines, and probation.
Beyond incarceration, convictions often result in:
