Mens rea is the mental element of a person's intention to commit a crime; or knowledge that one's action or lack of action would cause a crime to be committed. It is a necessary element of many crimes.
Burden of proof is a legal duty that encompasses two connected but separate ideas that apply for establishing the truth of facts in a trial before tribunals in the United States: the "burden of production" and the "burden of persuasion." In a legal dispute, one party is initially presumed to be correct, while the other side bears the burden of producing evidence persuasive enough to establish the truth of facts needed to satisfy all the required legal elements of legal dispute. There are varying types of burden of persuasion commonly referred to as standards of proof, and depending on the type of case, the standard of proof will be higher or lower. Burdens of persuasion and production may be of different standards for each party, in different phases of litigation. The burden of production is a minimal burden to produce at least enough evidence for the trier of fact to consider a disputed claim. After litigants have met the burden of production, they have the burden of persuasion: that enough evidence has been presented to persuade the trier of fact that their side is correct. There are different standards of persuasiveness ranging from a preponderance of the evidence, where there is just enough evidence to tip the balance, to proof beyond a reasonable doubt, as in United States criminal courts.
In law, a verdict is the formal finding of fact made by a jury on matters or questions submitted to the jury by a judge. In a bench trial, the judge's decision near the end of the trial is simply referred to as a finding. In England and Wales, a coroner's findings used to be called verdicts but are, since 2009, called conclusions.
Apprendi v. New Jersey, 530 U.S. 466 (2000), is a landmark United States Supreme Court decision with regard to aggravating factors in crimes. The Court ruled that the Sixth Amendment right to a jury trial, incorporated against the states through the Fourteenth Amendment, prohibited judges from enhancing criminal sentences beyond statutory maxima based on facts other than those decided by the jury beyond a reasonable doubt. The decision has been a cornerstone in the modern resurgence in jury trial rights. As Justice Scalia noted in his concurring opinion, the jury-trial right "has never been efficient; but it has always been free."
Beyond a reasonable doubt is a legal standard of proof required to validate a criminal conviction in most adversarial legal systems. It is a higher standard of proof than the balance of probabilities and is usually therefore reserved for criminal matters where what is at stake is considered more serious and therefore deserving of a higher threshold.
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 judicial system of Israel consists of secular courts and religious courts. The law courts constitute a separate and independent unit of Israel's Ministry of Justice. The system is headed by the President of the Supreme Court and the Minister of Justice.
In law, a trial is a coming together of parties to a dispute, to present information in a tribunal, a formal setting with the authority to adjudicate claims or disputes. One form of tribunal is a court. The tribunal, which may occur before a judge, jury, or other designated trier of fact, aims to achieve a resolution to their dispute.
The criminal law of Canada is under the exclusive legislative jurisdiction of the Parliament of Canada. The power to enact criminal law is derived from section 91(27) of the Constitution Act, 1867. Most criminal laws have been codified in the Criminal Code, as well as the Controlled Drugs and Substances Act, Youth Criminal Justice Act and several other peripheral statutes.
R v Chaulk, [1990] 3 SCR 1303 is a leading decision of the Supreme Court of Canada on the interpretation and constitutionality of section 16(4) of the Criminal Code, which provides for a mental disorder defence. Two accused individuals challenged the section as a violation of their right to the presumption of innocence under section 11(d) of the Charter of Rights and Freedoms ("Charter"). The Court upheld the section and provided a basis on which to interpret the section.
Dunlop v R, [1979] 2 S.C.R. 881 is the leading decision of the Supreme Court of Canada on participating in a criminal act by aiding and abetting. The Court held that the mere presence of the accused at the scene of a criminal act is not sufficient to convict the person for aiding and abetting a criminal act. There must be something more.
A rape shield law is a law that limits the ability to introduce evidence or cross-examine rape complainants about their past sexual behaviour. The term also refers to a law that prohibits the publication of the identity of an alleged rape victim.
Old Chief v. United States, 519 U.S. 172 (1997), discussed the limitation on admitting relevant evidence set forth in Federal Rule of Evidence 403. Under this rule, otherwise relevant evidence may be excluded if the probative value of the evidence is substantially outweighed by the danger of unfair prejudice, confusion of the issues, misleading the jury, or considerations of undue delay, wasting time, or needless presentation of cumulative evidence. In this case, Old Chief offered to stipulate to the fact of a prior conviction, which was an element of the crime with which he was charged. The prosecution resisted this stipulation, arguing that it had the right to present its case in any manner it chose. In Old Chief, the Court applied Rule 403 to the particular situation presented by this case, and concluded that Rule 403 required the trial court to accept the defendant's stipulation to a prior conviction over the prosecution's objection.
The Williams Rule is based on the holding in the Florida state case of Williams v. State in which relevant evidence of collateral crimes is admissible at jury trial when it does not go to prove the "bad character" or "criminal propensity" of the defendant but is used to show motive, intent, knowledge, modus operandi, or lack of mistake.
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 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.
No case for the defendant to answer is a term in the criminal law of some Commonwealth states, whereby a defendant seeks acquittal without having to present a defence, because of the insufficiency of the prosecution's case. The motion is infrequently used in civil cases where the defendant asserts that the plaintiff's case is insufficient to prove liability.
United States criminal procedure derives from several sources of law: the baseline protections of the United States Constitution, federal and state statutes; federal and state rules of criminal procedure ; and state and federal case law. Criminal procedures are distinct from civil procedures in the US.
R v W (D), [1991] 1 S.C.R. 742 is a leading decision of the Supreme Court of Canada on assessing guilt based on the credibility of witnesses in a criminal trial. More specifically, W.D. examines sexual assault cases and burdens of proof in evidence law.
The Double Jeopardy Clause of the Fifth Amendment to the United States Constitution provides: "[N]or shall any person be subject for the same offence to be twice put in jeopardy of life or limb..." The four essential protections included are prohibitions against, for the same offense:
R v Hibbert, [1995] 2 SCR 973, is a Supreme Court of Canada decision on aiding and abetting and the defence of duress in criminal law. The court held that duress is capable of negating the mens rea for some offences, but not for aiding the commission of an offence under s. 21(1)(b) of the Criminal Code. Nonetheless, duress can still function as an excuse-based defence.
