Foundation (evidence)
In common law, a foundation is sufficient preliminary evidence of the authenticity and relevance for the admission of material evidence in the form of exhibits or testimony of witnesses. Although the word "Foundation" does not appear in the Federal Rules of Evidence, scholars have argued that its existence is displayed, albeit implicitly, when viewing all the rules in context. Material evidence is important evidence that may serve to determine the outcome of a case. Exhibits include real evidence, illustrative evidence, demonstrative evidence, and documentary evidence. The type of preliminary evidence necessary to lay the proper foundation depends on the form and type of material evidence offered. Further, a proper foundation must be laid with respect to witness testimony.Fed. R. Evid. 602. The type of questioning and evidence necessary to properly lay a witness foundation differs based on what the witness is testifying to, and in what capacity they are testifying.Fed. R. Evid. ...

Common Law (legal System)
Common law (also known as judicial precedent, judge-made law, or case law) is the body of law primarily developed through judicial decisions rather than statutes. Although common law may incorporate certain statutes, it is largely based on precedent—judicial rulings made in previous similar cases. The presiding judge determines which precedents to apply in deciding each new case. Common law is deeply rooted in ''stare decisis'' ("to stand by things decided"), where courts follow precedents established by previous decisions. When a similar case has been resolved, courts typically align their reasoning with the precedent set in that decision. However, in a " case of first impression" with no precedent or clear legislative guidance, judges are empowered to resolve the issue and establish new precedent. The common law, so named because it was common to all the king's courts across England, originated in the practices of the courts of the English kings in the centuries following t ...

Evidence (law)
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. The Quantum meruit, quantum of evidence is the amount of evidence needed; the quality of proof is how reliable such evidence should be considered. Important rules that govern Admissible evidence, admissibility concern hearsay, Authentication (law), authentication, Relevance (law), relevance, privilege (evidence), privilege, witnesses, opinions, Expert witness, expert tes ...

Authentication (law)
Authentication, in the law of evidence, is the process by which documentary evidence and other physical evidence is proven to be genuine, and not a forgery. Generally, authentication can be shown in one of two ways. First, a witness can testify as to the chain of custody through which the evidence passed from the time of the discovery up until the trial. Second, the evidence can be authenticated by the opinion of an expert witness examining the evidence to determine if it has all of the properties that it would be expected to have if it were authentic. Types of documents For handwritten documents, any person who has become familiar with the purported author's handwriting prior to the cause of action from which the trial arose can testify that a document is in that handwriting. Alternatively, a handwriting expert can be called to testify based on their expertise in the field and examination of samples that the handwriting on the document is authentic. There are several kinds of ...

Relevance (law)
Relevance, in the common law of evidence, is the tendency of a given item of evidence to prove or disprove one of the legal elements of the case, or to have probative value to make one of the elements of the case likelier or not. Probative is a term used in law to signify "tending to prove". Probative evidence "seeks the truth". Generally in law, evidence that is not probative (doesn't tend to prove the proposition for which it is proffered) is inadmissible and the rules of evidence permit it to be excluded from a proceeding or stricken from the record "if objected to by opposing counsel". A balancing test may come into the picture if the value of the evidence needs to be weighed versus its prejudicial nature. Under the Federal Rules of Evidence (United States) Until the Federal Rules of Evidence were restyled in 2011, Rule 401 defined relevance as follows: This definition incorporates the requirement that evidence be both material ("of consequence to the determination of the ...

Admissible Evidence
Admissible evidence, in a court of law, is any Testimony, testimonial, Documentary evidence, documentary, or tangible evidence (law), evidence that may be introduced to a Trier of fact, factfinder—usually a judge or jury—to establish or to bolster a point put forth by a party to the proceeding. For evidence to be admissible, it must be relevance (law), relevant and "not excluded by the rules of evidence", which generally means that it must not be unfairly Prejudice (legal term), prejudicial, and it must have some indicia of reliability. The general rule in evidence is that all relevant evidence is admissible and all irrelevant evidence is inadmissible, though some countries (such as the Law of the United States, United States and, to an extent, Australian legal system, Australia) proscribe the prosecution from exploiting evidence False evidence, obtained in violation of constitutional law, thereby rendering relevant evidence inadmissible. This law of evidence, rule of eviden ...

Testimony
Testimony is a solemn attestation as to the truth of a matter. Etymology The words "testimony" and "testify" both derive from the Latin word ''testis'', referring to the notion of a disinterested third-party witness. Law In the law, testimony is a form of evidence in which a witness makes a "solemn declaration or affirmation ... for the purpose of establishing or proving some fact". According to Bryan A. Garner, the editor of '' Black's Law Dictionary'', the word "testimony" is properly used as a mass noun (that is, always uninflected regardless of number), and not a count noun. Testimony may be oral or written, and it is usually made by oath or affirmation under penalty of perjury. Historically, to be admissible in court and to ensure maximum reliability and validity, written testimony presented in the form of an affidavit (i.e., the witness would not be appearing in court at the hearing at which the affidavit was considered as evidence) was usually witnessed by anot ...

Witness
In law, a witness is someone who, either voluntarily or under compulsion, provides testimonial evidence, either oral or written, of what they know or claim to know. A witness might be compelled to provide testimony in court, before a grand jury, before an administrative tribunal, before a deposition officer, or in a variety of other legal proceedings. A subpoena is a legal document that commands a person to appear at a proceeding. It is used to compel the testimony of a witness in a trial (law), trial. Usually, it can be issued by a judge or by the lawyer representing the plaintiff or the defendant in a civil trial or by the prosecutor or the defense attorney in a Criminal procedure, criminal proceeding, or by a government agency. In many jurisdictions, it is compulsory to comply with the subpoena and either take an oath or solemnly Affirmation in law, affirm to testify truthfully under penalty of perjury. Although informally a witness includes whoever perceived the event, in l ...

Materiality (law)
Materiality is the significance of facts to the matter at hand.Black's Law Dictionary, 7th ed. In the law of evidence An item of evidence is said to be material if it has some logical connection to a fact of consequence to the outcome of a case. Materiality, along with probative value, is one of two characteristics that make a given item of evidence relevant. This largely depends on the elements of the cause of action the plaintiff seeks to prove, or that the prosecutor must prove in a criminal case to secure a conviction. Which issues must be factually proven are therefore a product of the underlying substantive law. In corporate and securities law Within the context of corporate and securities law in the United States, a fact is defined as material if there is a substantial likelihood that a reasonable shareholder would consider it important in deciding how to vote their shares or invest their money. In this regard, it is similar to the accounting term of the same name. M ...

Real Evidence
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. In American law Tampering 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."67 Corpus Juris Secundum ''Obstructing Justice'' § 63 (footnotes omitted). This is also a crime under statutes of many U.S. states. A 2004 review found that 32 states had a statute "that prohibits, in some form, the concealment, destruction, or tampering with evidence."John F. Decker, ''The Varying Parameters of Obstruction of Justice in American Criminal Law'', 65 LA. L. Rev. 40, 83-84 (2004). Evidence tampering "generally refers to physical evidence and is no ...

Demonstrative Evidence
Demonstrative evidence is evidence in the form of a representation of an object. This is, as opposed to, real evidence, testimony, or other forms of evidence used at trial. Examples Examples of demonstrative evidence include photos, x-rays, videotapes, movies, sound recordings, forensic animation, diagrams, maps, drawings and other trial graphics, simulations, and models. It is useful for assisting a finder of fact in establishing context among the facts presented in a case. To be admissible, a demonstrative exhibit must “fairly and accurately” represent the real object at the relevant time. See Federal Rules of Evidence 901, 902, and 1001-1004 for an example from United States law. Other examples of demonstrative evidence include case specific medical exhibits, colorized diagnostic films, general anatomy and surgery exhibits. These forms of demonstrative evidence are commonly used as a personal injury lawyer resource. Demonstrative evidence with dramatic impact can ...

Documentary Evidence
Documentary evidence is any evidence that is, or can be, introduced at a trial in the form of documents, as distinguished from oral testimony. Documentary evidence is most widely understood to refer to writings on paper (such as an invoice, a contract or a will), but the term can also apply to any media by which information can be preserved, such as photographs; a medium that needs a mechanical device to be viewed, such as a tape recording or film; and a printed form of digital evidence, such as emails or spreadsheets. Normally, before documentary evidence is admissible as evidence, it must be proved by other evidence from a witness that the document is genuine, called " laying a foundation". As a general rule of evidence, a document shall be proved by primary evidence that is document itself. No oral evidence of content of documents shall be admissible. But in certain circumstances the secondary evidence of documents including the oral evidence can be given. For instance, when ...

Objection (United States Law)
In the law of the United States of America, an objection is a formal protest to evidence, argument, or questions that are in violation of the rules of evidence or other procedural law. Objections are often raised in court during a trial to disallow a witness's testimony, and may also be raised during depositions and in response to written discovery. During trials and depositions, an objection is typically raised after the opposing party asks a question of the witness, but before the witness can answer, or when the opposing party is about to enter something into evidence. At trial, the judge then makes a ruling on whether the objection is "''sustained''" (the judge agrees with the objection and disallows the question, testimony, or evidence) or "''overruled''" (the judge disagrees with the objection and allows the question, testimony, or evidence). An attorney may choose to "rephrase" a question that has been objected to, so long as the judge permits it. Lawyers should make ...
