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 ...

Exclusionary Rule
In the United States, the exclusionary rule is a legal rule, based on constitutional law, that prevents evidence collected or analyzed in violation of the defendant's constitutional rights from being used in a court of law. This may be considered an example of a prophylactic rule formulated by the judiciary in order to protect a constitutional right. The exclusionary rule may also, in some circumstances at least, be considered to follow directly from the constitutional language, such as the Fifth Amendment's command that no person "shall be compelled in any criminal case to be a witness against himself" and that no person "shall be deprived of life, liberty or property without due process of law". The exclusionary rule is grounded in the Fourth Amendment in the Bill of Rights, and it is intended to protect citizens from illegal searches and seizures. The exclusionary rule is also designed to provide a remedy and disincentive for criminal prosecution from prosecutors and po ...

Scientific Evidence
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, although scientists also use evidence in other ways, such as when applying theories to practical problems. "Discussions about empirical evidence have tended to focus on epistemological questions regarding its role in theory testing ... even though empirical evidence also plays important and philosophically interesting roles in other areas including scientific discovery, the development of experimental tools and techniques, and the application of scientific theories to practical problems." Such evidence is expected to be empirical evidence and interpretable in accordance with the scientific method. Standards for scientific evidence vary according to the field of inquiry, but the strength of scientific evidence is generally based on the results of Statistics, statistical analysis and the strength of scientific controls. Principles of inference A person's assumptions or ...

Daubert V
In United States federal law, the ''Daubert'' standard ( ) is a rule of evidence regarding the admissibility of expert witness testimony. A party may raise a ''Daubert'' motion, a special motion ''in limine'' raised before or during trial, to exclude the presentation of unqualified evidence to the jury. The ''Daubert'' trilogy are the three United States Supreme Court cases that articulated the ''Daubert'' standard: *'' Daubert v. Merrell Dow Pharmaceuticals, Inc.'' (1993), which held that Rule 702 of the Federal Rules of Evidence did not incorporate the ''Frye'' standard as a basis for assessing the admissibility of scientific expert testimony, but that the rule incorporated a flexible reliability standard instead; *'' General Electric Co. v. Joiner'' (1997), which held that a district court judge may exclude expert testimony when there are gaps between the evidence relied on by an expert and that person's conclusion, and that an abuse-of-discretion standard of review is the pro ...

Chain Of Custody
Chain of custody (CoC), in legal contexts, is the chronological documentation or paper trail that records the sequence of custody, control, transfer, analysis, and disposition of materials, including physical or electronic evidence. Of particular importance in criminal cases, the concept is also applied in civil litigation and more broadly in drug testing of athletes and in supply chain management, e.g. to improve the traceability of food products, or to provide assurances that wood products originate from sustainably managed forests. It is often a tedious process that has been required for evidence to be shown legally in court. Now, however, with new portable technology that allows accurate laboratory quality results from the scene of the crime, the chain of custody is often much shorter which means evidence can be processed for court much faster. The term is also sometimes used in the fields of history, art history, and archives as a synonym for provenance (meaning the chron ...

Hearsay
Hearsay, in a legal forum, is an out-of-court statement which is being offered in court for the truth of what was asserted. In most courts, hearsay evidence is Inadmissible evidence, inadmissible (the "hearsay evidence rule") unless an exception to the hearsay rule applies. For example, to prove that Tom was in town, a witness testifies, "Susan told me that Tom was in town." Because the witness's evidence relies on an out-of-court statement that Susan made, if Susan is unavailable for cross-examination, the answer is hearsay. A justification for the objection is that the person who made the statement is not in court and thus not available for cross-examination. Note, however, that if the matter at hand is not the truth of the assertion about Tom being in town but the fact that Susan said the specific words, it may be acceptable. For example, it would be acceptable to ask a witness what Susan told them about Tom in a defamation case against Susan. Now the witness is asked about the ...

Lay A Foundation
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. ...

Consciousness Of Guilt
In the law of evidence, consciousness of guilt is a type of circumstantial evidence that judges, prosecutors, and juries may consider when determining whether a defendant is guilty of a criminal offense. It is often admissible evidence, and judges are required to instruct juries on this form of evidence. Deceptive statements or evasive actions made by a defendant after the commission of a crime or other wrongdoing are seen as evidence of a guilty conscience. These are not the typical behaviors of an innocent person, and a "defendant's actions are compared unfavorably to what a normal, innocent person would have done, with the implication that the discrepancy indicates guilt". Descriptions and definitions Consciousness of guilt law and legal definition: Criminal defense attorney Stephen G. Rodriguez describes it thus: The New York State Unified Court System discusses false alibis (in the context of "consciousness of guilt") as a form of admissible evidence: Haim Co ...

Warrantless Searches In The United States
Warrantless searches are Search and seizure, searches and seizures conducted without court-issued search warrants. In the United States, warrantless searches are restricted under the Fourth Amendment to the United States Constitution, part of the United States Bill of Rights, Bill of Rights, which states, "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by oath or Affirmation in law, affirmation, and particularly describing the place to be searched, and the persons or things to be seized." History In the Thirteen Colonies, agents of the British Empire utilized general warrants to authorize searches in the homes of colonists. Such warrants allowed the holder to search any place for any thing at any time. They were viewed as abuses of power, contributing to increased tensions that ultimately led to the American Revolut ...

Weeks V
A week is a unit of time equal to seven days. It is the standard time period used for short cycles of days in most parts of the world. The days are often used to indicate common work days and rest days, as well as days of worship. Weeks are often mapped against yearly calendars. There are just over 52 weeks in a year. The term "week" may also be used to refer to a sub-section of the week, such as the workweek and weekend. Ancient cultures had different "week" lengths, including ten days in Egypt and an eight-day week for Etruscans. The Etruscan week was adopted by the ancient Romans, but they later moved to a seven-day week, which had spread across Western Asia and the Eastern Mediterranean due to the influence of the Christian seven-day week, which is rooted in the Jewish seven-day week. In AD 321, Emperor Constantine the Great officially decreed a seven-day week in the Roman Empire, including making Sunday a public holiday. This later spread across Europe, then the rest of the ...
