Commonwealth v. York, 50 Mass. (9 Metcalf) 93 (1845), is a precedent-setting American criminal case that established the principle that although the prosecution must prove all elements of a crime beyond a reasonable doubt, the defendant bears the burden of proving the defense of provocation, which pertains to the defendant's mental state. [1] : 17 This ruling was consistent with Blackstone's Commentaries, which held that prosecution must prove the defendant committed a criminal act, and the defendant must then prove "circumstances of justification, excuse and alleviation". [1] : 17 [2] However, in federal courts, but not state all courts, this precedent was later modified by Davis v. United States (1895), which established the presumption of innocence regarding a defendant's mental state of being "legally capable of committing crime". [1] : 17
The insanity defense, also known as the mental disorder defense, is an affirmative defense by excuse in a criminal case, arguing that the defendant is not responsible for their actions due to a psychiatric disease at the time of the criminal act. This is contrasted with an excuse of provocation, in which the defendant is responsible, but the responsibility is lessened due to a temporary mental state. It is also contrasted with the justification of self defense or with the mitigation of imperfect self-defense. The insanity defense is also contrasted with a finding that a defendant cannot stand trial in a criminal case because a mental disease prevents them from effectively assisting counsel, from a civil finding in trusts and estates where a will is nullified because it was made when a mental disorder prevented a testator from recognizing the natural objects of their bounty, and from involuntary civil commitment to a mental institution, when anyone is found to be gravely disabled or to be a danger to themself or to others.
In law, a plea is a defendant's response to a criminal charge. A defendant may plead guilty or not guilty. Depending on jurisdiction, additional pleas may be available, including nolo contendere, no case to answer, or an Alford plea.
The Sixth Amendment to the United States Constitution sets forth rights related to criminal prosecutions. It was ratified in 1791 as part of the United States Bill of Rights. The Supreme Court has applied all but one of this amendment's protections to the states through the Due Process Clause of the Fourteenth Amendment.
Criminal procedure is the adjudication process of the criminal law. While criminal procedure differs dramatically by jurisdiction, the process generally begins with a formal criminal charge with the person on trial either being free on bail or incarcerated, and results in the conviction or acquittal of the defendant. Criminal procedure can be either in form of inquisitorial or adversarial criminal procedure.
In criminal law, mens rea is the mental state of a defendant who is accused of committing a crime. In common law jurisdictions, most crimes require proof both of mens rea and actus reus before the defendant can be found guilty.
In a legal dispute, one party has the burden of proof to show that they are correct, while the other party has no such burden and is presumed to be correct. The burden of proof requires a party to produce evidence to establish the truth of facts needed to satisfy all the required legal elements of the dispute.
Civil procedure is the body of law that sets out the rules and regulations along with some standards that courts follow when adjudicating civil lawsuits. These rules govern how a lawsuit or case may be commenced; what kind of service of process is required; the types of pleadings or statements of case, motions or applications, and orders allowed in civil cases; the timing and manner of depositions and discovery or disclosure; the conduct of trials; the process for judgment; the process for post-trial procedures; various available remedies; and how the courts and clerks must function.
The presumption of innocence is a legal principle that every person accused of any crime is considered innocent until proven guilty. Under the presumption of innocence, the legal burden of proof is thus on the prosecution, which must present compelling evidence to the trier of fact. If the prosecution does not prove the charges true, then the person is acquitted of the charges. The prosecution must in most cases prove that the accused is guilty beyond a reasonable doubt. If reasonable doubt remains, the accused must be acquitted. The opposite system is a presumption of guilt.
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.
In the legal system of the United States, a Brady disclosure consists of exculpatory or impeaching information and evidence that is material to the guilt or innocence or to the punishment of a defendant. The term comes from the 1963 U.S. Supreme Court case Brady v. Maryland, in which the Supreme Court ruled that suppression by the prosecution of evidence favorable to a defendant who has requested it violates due process.
Lemuel Shaw was an American jurist who served as chief justice of the Massachusetts Supreme Judicial Court (1830–1860). Prior to his appointment he also served for several years in the Massachusetts House of Representatives and as a state senator. In 1847, Shaw became the father-in-law of author Herman Melville. He ruled on prominent cases involving slavery, segregation, and religion.
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 standard of balance of probabilities commonly used in civil cases because the stakes are much higher in a criminal case: a person found guilty can be deprived of liberty or, in extreme cases, life, as well as suffering the collateral consequences and social stigma attached to a conviction. The prosecution is tasked with providing evidence that establishes guilt beyond a reasonable doubt in order to get a conviction; albeit prosecution may fail to complete such task, the trier-of-fact's acceptance that guilt has been proven beyond a reasonable doubt will in theory lead to conviction of the defendant. A failure for the trier-of-fact to accept that the standard of proof of guilt beyond a reasonable doubt has been met thus entitles the accused to an acquittal. This standard of proof is widely accepted in many criminal justice systems, and its origin can be traced to Blackstone's ratio, "It is better that ten guilty persons escape than that one innocent suffer."
Actual innocence is a special standard of review in legal cases to prove that a charged defendant did not commit the crimes that they were accused of, which is often applied by appellate courts to prevent a miscarriage of justice.
The Domestic Violence, Crime and Victims Act 2004 is an Act of the Parliament of the United Kingdom. It is concerned with criminal justice and concentrates upon legal protection and assistance to victims of crime, particularly domestic violence. It also expands the provision for trials without a jury, brings in new rules for trials for causing the death of a child or vulnerable adult, and permits bailiffs to use force to enter homes.
In the law of England and Wales, fitness to plead is the capacity of a defendant in criminal proceedings to comprehend the course of those proceedings. The concept of fitness to plead also applies in Scots and Irish law. Its United States equivalent is competence to stand trial.
Criminal damage in English law was originally a common law offence. The offence was largely concerned with the protection of dwellings and the food supply, and few sanctions were imposed for damaging personal property. Liability was originally restricted to the payment of damages by way of compensation.
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:
Leland v. Oregon, 343 U.S. 790 (1952), was a United States Supreme Court case in which the Court upheld the constitutionality of placing the burden of persuasion on the defendant when they argue an insanity defense in a criminal trial. This differed from previous federal common law established in Davis v. United States, in which the court held that if the defense raised an insanity defense, the prosecution must prove sanity beyond a reasonable doubt, but Davis was not a United States constitutional ruling, so only limited federal cases, but not state cases. Oregon had a very high burden on defense, that insanity be proved beyond a reasonable doubt. At that time, twenty other states also placed the burden of persuasion on the defense for an insanity defense.
Intoxication in English law is a circumstance which may alter the capacity of a defendant to form mens rea, where a charge is one of specific intent, or may entirely negate mens rea where the intoxication is involuntary. The fact that a defendant is intoxicated in the commission of a crime — whether voluntarily or not — has never been regarded as a full defence to criminal proceedings. Its development at common law has been shaped by the acceptance that intoxicated individuals do not think or act as rationally as they would otherwise, but also by a public policy necessity to punish individuals who commit crimes.
The Taney Court heard thirty criminal law cases, approximately one per year. Notable cases include Prigg v. Pennsylvania (1842), United States v. Rogers (1846), Ableman v. Booth (1858), Ex parte Vallandigham (1861), and United States v. Jackalow (1862).
