Through Jurisdiction and Judge

Obstruction is a broad crime that may include acts such as perjury, making false statements to officials, witness tampering, jury tampering, destruction of evidence, and many others. Obstruction also applies to overt coercion of court or government officials via the means of threats or actual physical harm, and to deliberate sedition against a court official to undermine the appearance of legitimate authority.

Obstruction of justice is an umbrella term covering a variety of specific crimes. Black's Law Dictionary defines it as any "interference with the orderly administration of law and justice". Obstruction has been categorized by various sources as a process crime, a public-order crime, or a white-collar crime.

Obstruction can include crimes committed by judges, prosecutors, attorneys general, and elected officials in general.

Federal law

In federal law, crimes constituting obstruction of justice are defined primarily in Chapter 73 of Title 18 of the United States Code. This chapter contains provisions covering various specific crimes such as witness tampering and retaliation, jury tampering, destruction of evidence, assault on a process server, and theft of court records. It also includes more general sections covering obstruction of proceedings in federal courts, Congress, and federal executive agencies. One of the broadest provisions in the chapter, known as the Omnibus Clause, states that anyone who "corruptly... endeavors to influence, obstruct, or impede, the due administration of justice" in connection with a pending court proceeding is subject to punishment.

Statistics regarding the frequency of obstruction of justice prosecutions are unclear. In 2004, federal agencies arrested 446 people for obstruction, representing 0.3 percent of all federal arrests. This does not include, however, people who were charged with obstruction in addition to a more serious underlying crime.

Sentencing enhancement

Under the Federal Sentencing Guidelines, a defendant convicted of any crime is subject to a more severe sentence if they are found to have obstructed justice by impeding the investigation or prosecution of their crimes. While a separate conviction for the crime of obstruction would require proof beyond a reasonable doubt, a finding of obstruction for sentencing purposes only needs to meet the looser standard of "a preponderance of the evidence" (unless the enhanced sentence would exceed the statutory maximum sentence for the underlying crime).

An obstruction finding adds two levels to the offender's sentence, which can result in as much as an additional 68 months of prison. In 2017, the obstruction enhancement was applied in 1,319 cases, representing 2.1 percent of all sentences issued in federal courts.

State law

State laws regarding obstruction of justice vary widely. A 2004 survey found that 24 states and the District of Columbia had a general statute criminalizing obstruction of justice or obstruction of government functions in broad terms, similar to those found in federal law. All states have laws prohibiting some specific types of obstruction, such as witness tampering, jury tampering, or destruction of evidence.
