Murder is the unlawful killing of another human without justification or valid excuse, especially the unlawful killing of another human with malice aforethought. This state of mind may, depending upon the jurisdiction, distinguish murder from other forms of unlawful homicide, such as manslaughter. Manslaughter is killing committed in the absence of malice, brought about by reasonable provocation, or diminished capacity. Involuntary manslaughter, where it is recognized, is a killing that lacks all but the most attenuated guilty intent, recklessness.
The gay panic defense is a legal strategy in which a defendant claims they acted in a state of violent temporary insanity, committing assault or murder, because of unwanted same-sex sexual advances. Broadly, a defendant may allege to have found the same-sex sexual advances so offensive or frightening that they were provoked into reacting, were acting in self-defense, were of diminished capacity, or were temporarily insane, and that this circumstance is exculpatory or mitigating.
In English law, the benefit of clergy was originally a provision by which clergymen could claim that they were outside the jurisdiction of the secular courts and be tried instead in an ecclesiastical court under canon law. Various reforms limited the scope of this legal arrangement to prevent its abuse. Eventually the benefit of clergy evolved into a legal fiction in which first-time offenders could receive lesser sentences for some crimes. The legal mechanism was abolished in 1827 with the passage of the Criminal Law Act 1827
In law, provocation is when a person is considered to have committed a criminal act partly because of a preceding set of events that might cause a reasonable person to lose self control. This makes them less morally culpable than if the act was premeditated (pre-planned) and done out of pure malice. It "affects the quality of the actor's state of mind as an indicator of moral blameworthiness".
Actual malice in United States law is a legal requirement imposed upon public officials or public figures when they file suit for libel. Unlike other individuals who are less well-known to the general public, public officials and public figures are held to a higher standard for what they must prove before they may succeed in a defamation lawsuit.
Furman v. Georgia, 408 U.S. 238 (1972), was a criminal case in which the United States Supreme Court struck down all death penalty schemes in the United States in a 5–4 decision, with each member of the majority writing a separate opinion. Following Furman, in order to reinstate the death penalty, states had to at least remove arbitrary and discriminatory effects, to satisfy the Eighth Amendment to the United States Constitution.
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."
Malice is a legal term referring to a party's intention to do injury to another party. Malice is either expressed or implied. Malice is expressed when there is manifested a deliberate intention to unlawfully take away the life of a human being. Malice is implied when no considerable provocation appears, or when the circumstances attending the killing show an abandoned and malignant heart. Malice, in a legal sense, may be inferred from the evidence and imputed to the defendant, depending on the nature of the case.
Malice aforethought is the "premeditation" or "predetermination" required as an element of some crimes in some jurisdictions and a unique element for first-degree or aggravated murder in a few. Insofar as the term is still in use, it has a technical meaning that has changed substantially over time.
Manslaughter is a common law legal term for homicide considered by law as less culpable than murder. The distinction between murder and manslaughter is sometimes said to have first been made by the ancient Athenian lawmaker Draco in the 7th century BC.
Jones v. United States, 526 U.S. 227 (1999), is a United States Supreme Court case interpreting the federal carjacking statute, 18 U.S.C. § 2119, to set forth three distinct crimes, each with distinct elements. The Court drew this conclusion from the structure of the statute, under which two subsections provided for additional punishment if the defendant inflicts more serious harm. The Court also distinguished Almendarez-Torres v. United States, 523 U.S. 224 (1998), because that case allowed for sentencing enhancement based on a prior conviction.
Patterson v. New York, 432 U.S. 197 (1977), is a legal case heard by the United States Supreme Court regarding the constitutionality under the Fourteenth Amendment's Due Process Clause of burdening a defendant with proving the affirmative defense of extreme emotional disturbance as defined by New York law.
The origins of the United States' defamation laws pre-date the American Revolution; one influential case in 1734 involved John Peter Zenger and established precedent that "The Truth" is an absolute defense against charges of libel. Though the First Amendment of the U.S. Constitution was designed to protect freedom of the press, for most of the history of the United States, the U.S. Supreme Court failed to use it to rule on libel cases. This left libel laws, based upon the traditional "Common Law" of defamation inherited from the English legal system, mixed across the states. The 1964 case New York Times Co. v. Sullivan, however, radically changed the nature of libel law in the United States by establishing that public officials could win a suit for libel only when they could prove the media outlet in question knew either that the information was wholly and patently false or that it was published "with reckless disregard of whether it was false or not". Later Supreme Court cases barred strict liability for libel and forbid libel claims for statements that are so ridiculous as to be patently false. Recent cases have added precedent on defamation law and the Internet.
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:
In the United States, the law regarding murder varies by jurisdiction. In most US jurisdictions there is a hierarchy of acts, known collectively as homicide, of which first degree murder and felony murder are the most serious, followed by second degree murder, followed by voluntary manslaughter and involuntary manslaughter which are not as serious, and ending finally in justifiable homicide, which is not a crime. However, because there are at least 52 relevant jurisdictions, each with its own criminal code, this is a considerable simplification.
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 (1895), 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.
Responsibility for criminal law and criminal justice in the United States is shared between the states and the federal government.
Manslaughter is a crime in the United States. Definitions can vary among jurisdictions, but manslaughter is invariably the act of causing the death of another person in a manner less culpable than murder.
Smith v. United States, 568 U.S. 106 (2013), was a case decided by the Supreme Court of the United States of America. The case was argued on November 6, 2012 and decided on January 9th, 2013.
