Learned treatise

Last updated

A learned treatise, in the law of evidence, is a text that is sufficiently authoritative in its field to be admissible as evidence in a court in support of the contentions made therein.

Law System of rules and guidelines, generally backed by governmental authority

Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. It has been defined both as "the Science of Justice" and "the Art of Justice". Law is a system that regulates and ensures that individuals or a community adhere to the will of the state. State-enforced laws can be made by a collective legislature or by a single legislator, resulting in statutes, by the executive through decrees and regulations, or established by judges through precedent, normally in common law jurisdictions. Private individuals can create legally binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process. The formation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people.

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.

Court judicial institution with the authority to resolve legal disputes

A court is any person or institution with authority to judge or adjudicate, often as a government institution, with the authority to adjudicate legal disputes between parties and carry out the administration of justice in civil, criminal, and administrative matters in accordance with the rule of law. In both common law and civil law legal systems, courts are the central means for dispute resolution, and it is generally understood that all people have an ability to bring their claims before a court. Similarly, the rights of those accused of a crime include the right to present a defense before a court.

Under the common law, such evidence was at one time considered hearsay - a statement made out of court being introduced to prove the truth of the statement - and was not admissible except to rebut the testimony of an opposing expert witness. There were four ways to introduce such evidence:[ citation needed ]

Common law Law developed by judges

In law, common law is that body of law derived from judicial decisions of courts and similar tribunals. The defining characteristic of “common law” is that it arises as precedent. In cases where the parties disagree on what the law is, a common law court looks to past precedential decisions of relevant courts, and synthesizes the principles of those past cases as applicable to the current facts. If a similar dispute has been resolved in the past, the court is usually bound to follow the reasoning used in the prior decision. If, however, the court finds that the current dispute is fundamentally distinct from all previous cases, and legislative statutes are either silent or ambiguous on the question, judges have the authority and duty to resolve the issue. The court states an opinion that gives reasons for the decision, and those reasons agglomerate with past decisions as precedent to bind future judges and litigants. Common law, as the body of law made by judges, stands in contrast to and on equal footing with statutes which are adopted through the legislative process, and regulations which are promulgated by the executive branch. Stare decisis, the principle that cases should be decided according to consistent principled rules so that similar facts will yield similar results, lies at the heart of all common law systems.

Hearsay evidence is "an out-of-court statement offered to prove the truth of the matter asserted therein." In certain courts, hearsay evidence is inadmissible unless an exception to the Hearsay Rule applies.

An expert witness, in England, Wales and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized opinion about evidence or about facts before the court within the expert's area of expertise, referred to as an "expert opinion". Expert witnesses may also deliver "expert evidence" within the area of their expertise. Their testimony may be rebutted by testimony from other experts or by other evidence or facts.

  1. Adduce testimony that the opposing expert witness actually used that text to reach his conclusions;
  2. Adduce testimony by the opposing expert admitting that the text is an authority in the field;
  3. Have a friendly expert witness testifying against the opposing expert witness attest to the authoritativeness of the text.
  4. Have the judge take judicial notice of the text, if it is sufficiently notable that the average person would know that it is an authority (for example, Gray's Anatomy [1] [2] ).

Under the Federal Rules of Evidence 803 (18), either party can introduce a learned treatise as evidence, irrespective of whether it is being used to rebut the opposing party. Such texts are now considered an exception to hearsay, with two limitations: [3]

First adopted in 1975, the Federal Rules of Evidence codify the evidence law that applies in United States federal courts. In addition, many states in the United States have either adopted the Federal Rules of Evidence, with or without local variations, or have revised their own evidence rules or codes to at least partially follow the federal rules.

  1. For the learned treatise to be introduced, there must be an expert witness on the stand;
  2. Like a recorded recollection, the actual learned treatise does not go to the jury, but instead comes into evidence only by being read to the jury.

A witness is someone who has, who claims to have, or is thought, by someone with authority to compel testimony, to have knowledge relevant to an event or other matter of interest. In law a witness is someone who, either voluntarily or under compulsion, provides testimonial evidence, either oral or written, of what he or she knows or claims to know about the matter before some official authorized to take such testimony.

Hearsay is an out-of-court statement being offered to prove the truth of the matter asserted. The Federal Rules of Evidence prohibit introducing hearsay statements during applicable federal court proceedings, unless one of nearly thirty exemptions or exceptions applies. The Federal Rules of Evidence define hearsay as:

A statement that: (1) the declarant does not make while testifying at the current trial or hearing; and (2) a party offers in evidence to prove the truth of the matter asserted in the statement..

Crawford v. Washington, 541 U.S. 36 (2004), is a United States Supreme Court decision that reformulated the standard for determining when the admission of hearsay statements in criminal cases is permitted under the Confrontation Clause of the Sixth Amendment. The Court held that cross-examination is required to admit prior testimonial statements of witnesses who have since become unavailable.

The party admission, in the law of evidence, is a type of statement that appears to be hearsay but is generally exempted (excluded) from the definition of hearsay because it was made by a party to the litigation adverse to the party introducing it into evidence.

Admissible evidence, in a court of law, is any testimonial, documentary, or tangible evidence that may be introduced to a 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 relevant and "not excluded by the rules of evidence", which generally means that it must not be unfairly 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 proscribe the prosecution from exploiting evidence obtained in violation of constitutional law, thereby rendering relevant evidence inadmissible. This rule of evidence is called the exclusionary rule. In the United States this was effectuated federally in 1914 under the Supreme Court case Weeks v. United States and incorporated against the states in 1961 in the case Mapp v. Ohio, both of which involving law enforcement conducting warrantless searches of the petitioners' homes, with incriminating evidence being descried inside them.

Witness impeachment, in the law of evidence of the United States, is the process of calling into question the credibility of an individual testifying in a trial. The Federal Rules of Evidence contain the rules governing impeachment in US federal courts.

<i>R v Starr</i>

R v Starr [2000] 2 SCR 144 is a leading Supreme Court of Canada decision that re-evaluated several principles of evidence. In particular, they held the "principled approach" hearsay evidence under R v Khan and R v Smith (1992) can be equally used to exclude otherwise admissible hearsay evidence. In addition, the Court examined the judge's charge to the jury on the standard of beyond a reasonable doubt.

The Confrontation Clause of the Sixth Amendment to the United States Constitution provides that "in all criminal prosecutions, the accused shall enjoy the right…to be confronted with the witnesses against him." Generally, the right is to have a face-to-face confrontation with witnesses who are offering testimonial evidence against the accused in the form of cross-examination during a trial. The Fourteenth Amendment makes the right to confrontation applicable to the states and not just the federal government. The right only applies to criminal prosecutions, not civil cases or other proceedings.

The hearsay provisions of the Criminal Justice Act 2003 reformed the common law relating to the admissibility of hearsay evidence in criminal proceedings begun on or after 4 April 2005.

Prior consistent statements and prior inconsistent statements, in the law of evidence, occur where a witness, testifying at trial, makes a statement that is either consistent or inconsistent, respectively, with a previous statement given at an earlier time such as during a discovery, interview, or interrogation. The examiner can impeach the witness when an inconsistent statement is found, and may conversely bolster the credibility of an impeached witness with a prior consistent statement.

In the law of the United States of America, an objection is a formal protest raised in court during a trial to disallow a witness's testimony or other evidence which would be in violation of the rules of evidence or other procedural law. 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. The judge then makes a ruling on whether the objection is "sustained" or "overruled". An attorney may choose to "rephrase" a question that has been objected to, so long as the judge permits it. Lawyers should make an objection before there is an answer to the question.

The business records exception to the U.S. hearsay rule is based on Rule 803(6) of the Federal Rules of Evidence (FRE). It is sometimes referred to as the business entry rule.

<i>Commonwealth v. Brady</i>

Commonwealth v. Brady, 510 Pa. 123, 507 A.2d 66, is a case decided by the Supreme Court of Pennsylvania in 1986 which overruled close to two centuries of decisional law in Pennsylvania and established a common law exception to the rule against hearsay.

Tome v. United States, 513 U.S. 150 (1995), was a case decided by the Supreme Court of the United States that held that under Federal Rules of Evidence Rule 801(d)(1)(B), a prior consistent statement is not hearsay only if the statement was made before the motive to fabricate arose.

The role of expert witnesses in English law is to give explanations of difficult or technical topics in civil and criminal trials, to assist the fact finding process. The extent to which authorities have been allowed to testify, and on what topics, has been debated, and to this end a variety of criterion have evolved throughout English case law.

Beech Aircraft Corporation v. Rainey, 488 U.S. 153 (1988), was a United States Supreme Court case that addressed a longstanding conflict among the Federal Courts of Appeals over whether Federal Rule of Evidence 803(8)(C), which provides an exception to the hearsay rule for public investigatory reports containing "factual findings," extends to conclusions and opinions contained in such reports. The court also considered whether the trial court abused its discretion in refusing to admit, on cross-examination, testimony intended to provide a more complete picture of a document about which the witness had testified on direct.
