In evidence law, physical evidence (also called real evidence or material evidence) is any material object that plays some role in the matter that gave rise to the litigation, introduced as evidence in a judicial proceeding (such as a trial) to prove a fact in issue based on the object's physical characteristics.
It is an offense at common law "to tamper with, conceal, or destroy evidence knowing that it may be wanted in a judicial proceeding or is being sought by law enforcement officers." [1] This is also a crime under statutes of many U.S. states. [1] A 2004 review found that 32 states had a statute "that prohibits, in some form, the concealment, destruction, or tampering with evidence." [2] Evidence tampering "generally refers to physical evidence and is not founded on false statements or the concealment of information by false statements." [1] It falls within the broader set of obstruction of justice-related offenses; others include perjury, bribery, destruction of government property, contempt, and escape. [2]
Generally, the elements of the offense are: that the person had "knowledge that an official proceeding or investigation is in progress or is likely to be instituted"; that the person took (2) "overt action to alter, destroy, conceal, or remove evidence"; and that (3) the person had the "purpose of impairing the value or availability of the evidence in the proceeding or investigation." [1]
In Pennsylvania v. Muniz (1990), the U.S. Supreme Court "distinguished 'physical' and 'demeanor' evidence from 'testimonial' evidence, holding that evidence of the former does not engender Fifth Amendment protection" against self-incrimination. [3] The U.S. Court of Appeals for the Ninth Circuit has held that "physical evidence includes one's fingerprints, handwriting, vocal characteristics, stance, stride, gestures, or blood characteristics." [3]
Perjury is the intentional act of swearing a false oath or falsifying an affirmation to tell the truth, whether spoken or in writing, concerning matters material to an official proceeding.
Forgery is a white-collar crime that generally refers to the false making or material alteration of a legal instrument with the specific intent to defraud anyone. Tampering with a certain legal instrument may be forbidden by law in some jurisdictions but such an offense is not related to forgery unless the tampered legal instrument was actually used in the course of the crime to defraud another person or entity. Copies, studio replicas, and reproductions are not considered forgeries, though they may later become forgeries through knowing and willful misrepresentations.
Obstruction of justice, in United States jurisdictions, is a crime consisting of obstructing 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.
The Starr Report, officially the Referral from Independent Counsel Kenneth W. Starr in Conformity with the Requirement of Title 28, United States Code, Section 595(c), is a United States federal government report by Independent Counsel Ken Starr concerning his investigation of President Bill Clinton. Delivered to the United States Congress on September 9, 1998, the allegations in the report led to the impeachment of Bill Clinton and the five-year suspension of Clinton's law license.
Contempt of Congress is the act of obstructing the work of the United States Congress or one of its committees. Historically, the bribery of a U.S. senator or U.S. representative was considered contempt of Congress. In modern times, contempt of Congress has generally applied to the refusal to comply with a subpoena issued by a congressional committee or subcommittee—usually seeking to compel either testimony or the production of requested documents.
A miscarriage of justice occurs when a grossly unfair outcome occurs in a criminal or civil proceeding, such as the conviction and imprisonment of a person for a crime they did not commit. Miscarriages are also known as wrongful convictions. Innocent people have sometimes ended up in prison for years before their conviction has eventually been overturned. They may be exonerated if new evidence comes to light or it is determined that the police or prosecutor committed some kind of misconduct at the original trial. In some jurisdictions this leads to the payment of compensation.
False arrest is a common law tort, where a plaintiff alleges they were held in custody without probable cause, or without an order issued by a court of competent jurisdiction. Although it is possible to sue law enforcement officials for false arrest, the usual defendants in such cases are private security firms.
A crime scene is any location that may be associated with a committed crime. Crime scenes contain physical evidence that is pertinent to a criminal investigation. This evidence is collected by crime scene investigators (CSIs) and law enforcement. The location of a crime scene can be the place where the crime took place or can be any area that contains evidence from the crime itself. Scenes are not only limited to a location, but can be any person, place, or object associated with the criminal behaviours that occurred.
Witness tampering is the act of attempting to improperly influence, alter or prevent the testimony of witnesses within criminal or civil proceedings.
A false statement is a statement that is not true. Although the word fallacy is sometimes used as a synonym for false statement, that is not how the word is used in philosophy, mathematics, logic and most formal contexts.
The law of evidence, also known as the rules of evidence, encompasses the rules and legal principles that govern the proof of facts in a legal proceeding. These rules determine what evidence must or must not be considered by the trier of fact in reaching its decision. The trier of fact is a judge in bench trials, or the jury in any cases involving a jury. The law of evidence is also concerned with the quantum (amount), quality, and type of proof needed to prevail in litigation. The rules vary depending upon whether the venue is a criminal court, civil court, or family court, and they vary by jurisdiction.
Making false statements is the common name for the United States federal process crime laid out in Section 1001 of Title 18 of the United States Code, which generally prohibits knowingly and willfully making false or fraudulent statements, or concealing information, in "any matter within the jurisdiction" of the federal government of the United States, even by merely denying guilt when asked by a federal agent. A number of notable people have been convicted under the section, including Martha Stewart, Rod Blagojevich, Michael T. Flynn, Rick Gates, Scooter Libby, Bernard Madoff, and Jeffrey Skilling.
Title VIII: Strengthening the criminal laws against terrorism is the eighth of ten titles which comprise the USA PATRIOT Act, an anti-terrorism bill passed in the United States one month after the September 11, 2001 attacks. Title VIII contains 17 sections and creates definitions of terrorism, and establishes or re-defines rules with which to deal with it.
In United States criminal procedure terminology, a process crime is an offense against the judicial process. These crimes include failure to appear, false statements, obstruction of justice, contempt of court and perjury.
Tampering with evidence, or evidence tampering, is an act in which a person alters, conceals, falsifies, or destroys evidence with the intent to interfere with an investigation (usually) by a law-enforcement, governmental, or regulatory authority. It is a criminal offense in many jurisdictions.
Yates v. United States, 574 U.S. 528 (2015), was a United States Supreme Court case in which the Court construed 18 U.S.C. § 1519, a provision added to the federal criminal code by the Sarbanes-Oxley Act, to criminalize the destruction or concealment of "any record, document, or tangible object" to obstruct a federal investigation. By a 5-to-4 vote, the Court stated that the term "tangible object" as used in this section means an object used to record or preserve information, and that this did not include fish.
The Penal Code is a law that codifies most criminal offences and procedures in Malaysia. Its official long title is "An Act relating to criminal offences" [Throughout Malaysia—31 March 1976, Act A327; P.U. (B) 139/1976]. The sole jurisdiction of Parliament of Malaysia is established over criminal law in Malaysia.
Kingsley Books, Inc. v. Brown, 354 U.S. 436 (1957), was a Supreme Court case that addressed issues of obscenity, free speech, and due process. The case stemmed from the confiscation and destruction of books from a New York City bookstore. The court's determination was that:
A state injunction against distribution of material designated as "obscene" does not violate freedom of speech and press protected by the First Amendment and the Due Process Clause of the Fourteenth Amendment.
Conspiracy against the United States, or conspiracy to defraud the United States, is a federal offense in the United States of America under 18 U.S.C. § 371. The crime is that of two or more persons who conspire to commit an offense against the United States, or to defraud the United States.
Corruptly obstructing, influencing, or impeding an official proceeding is a felony under U.S. federal law. It was enacted as part of the Sarbanes–Oxley Act of 2002 as a reaction to the Enron scandal, and closed a legal loophole on who could be charged with evidence tampering by defining the new crime very broadly. It later became known for its use as a charge against defendants associated with the 2021 U.S. Capitol attack for attempting to obstruct that year's Electoral College vote count.
