Obstruction of justice

Obstruction of justice, in United States jurisdictions, is an act that involves unduly influencing, impeding, or otherwise interfering with the justice system, especially the legal and procedural tasks of prosecutors, investigators, or other government officials. Common law jurisdictions other than the United States tend to use the wider offense of perverting the course of justice.

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 also applying to deliberate sedition against a court official to undermine the appearance of legitimate authority.

History[edit]

From the creation of the federal courts by the Judiciary Act of 1789, judges had the power to summarily punish those who obstructed justice by holding them in contempt of court.[19][20]


A scandal in 1830 led to reform of the contempt law and the creation of obstruction of justice as a separate offense. Federal judge James H. Peck imprisoned a lawyer for contempt for publishing a letter criticizing one of Peck's opinions. In an effort to prevent such abuses, Congress passed a law in 1831 limiting the application of the summary contempt procedures to offenses committed in or near the court. A new section, which survives today as the Omnibus Clause, was added to punish contempts committed outside of the court, but only after indictment and trial by jury.[19][20]


In 1982, in response to concerns that the obstruction law did not provide adequate protection to crime victims and other witnesses, Congress broadened the law against witness tampering and criminalized retaliation against witnesses, as part of the Victim and Witness Protection Act.[21]


The Sarbanes–Oxley Act of 2002 strengthened the obstruction laws regarding destruction of evidence before an investigation or proceeding has begun, in response to accounting firm Arthur Andersen's widely reported shredding of documents related to the Enron scandal.[22]
