This is a list of the laws of murder by country. The legal definition of murder varies by country: the laws of different countries deal differently with matters such as mens rea (how the intention on the part of the alleged murderer must be proved for the offence to amount to murder) and sentencing.
Capital punishment, also known as the death penalty and formerly called judicial homicide, is the state-sanctioned practice of deliberately killing a person as a punishment for an actual or supposed crime, usually following an authorized, rule-governed process to conclude that the person is responsible for violating norms that warrant said punishment. The sentence ordering that an offender be punished in such a manner is known as a death sentence, and the act of carrying out the sentence is known as an execution. A prisoner who has been sentenced to death and awaits execution is condemned and is commonly referred to as being "on death row".
In jurisprudence, double jeopardy is a procedural defence that prevents an accused person from being tried again on the same charges following an acquittal or conviction and in rare cases prosecutorial and/or judge misconduct in the same jurisdiction. Double jeopardy is a common concept in criminal law. In civil law, a similar concept is that of res judicata. Variation in common law countries is the peremptory plea, which may take the specific forms of autrefois acquit or autrefois convict. These doctrines appear to have originated in ancient Roman law, in the broader principle non bis in idem.
Euthanasia is the practice of intentionally ending life to eliminate pain and suffering.
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.
A statute of limitations, known in civil law systems as a prescriptive period, is a law passed by a legislative body to set the maximum time after an event within which legal proceedings may be initiated. In most jurisdictions, such periods exist for both criminal law and civil law such as contract law and property law, though often under different names and with varying details.
Lesbian, gay, bisexual, and transgender (LGBT) people frequently experience violence directed toward their sexuality, gender identity, or gender expression. This violence may be enacted by the state, as in laws prescribing punishment for homosexual acts, or by individuals. It may be psychological or physical and motivated by biphobia, gayphobia, homophobia, lesbophobia, and transphobia. Influencing factors may be cultural, religious, or political mores and biases.
Mass murder is the act of murdering a number of people, typically simultaneously or over a relatively short period of time and in close geographic proximity. The United States Congress defines mass killings as the killings of three or more people during an event with no "cooling-off period" between the homicides. A mass murder typically occurs in a single location where one or more people kill a couple others.
The Aryan Brotherhood, also known as the Brand or the AB, is a neo-Nazi prison gang and an organized crime syndicate which is based in the United States and has an estimated 15,000–20,000 members both inside and outside prisons. The Southern Poverty Law Center (SPLC) has characterized it as "the nation's oldest major white supremacist prison gang and a national crime syndicate" while the Anti-Defamation League calls it the "oldest and most notorious racist prison gang in the United States". According to the Federal Bureau of Investigation (FBI), the Aryan Brotherhood makes up an extremely low percentage of the entire US prison population but it is responsible for a disproportionately large number of prison murders.
Homicide occurs when a person kills another person. A homicide requires only a volitional act or omission that causes the death of another, and thus a homicide may result from accidental, reckless, or negligent acts even if there is no intent to cause harm. Homicides can be divided into many overlapping legal categories, such as murder, manslaughter, justifiable homicide, assassination, killing in war, euthanasia, and capital punishment, depending on the circumstances of the death. These different types of homicides are often treated very differently in human societies; some are considered crimes, while others are permitted or even ordered by the legal system.
Life imprisonment is any sentence of imprisonment for a crime under which convicted people are to remain in prison for the rest of their natural lives or indefinitely until pardoned, paroled, or otherwise commuted to a fixed term. Some countries have life imprisonment sentences as 25 years, such as the USA. Crimes for which, in some countries, a person could receive this sentence include murder, torture, terrorism, child abuse resulting in death, rape, espionage, treason, drug trafficking, drug possession, human trafficking, severe fraud and financial crimes, aggravated criminal damage, arson, kidnapping, burglary, and robbery, piracy, aircraft hijacking, and genocide, crimes against humanity, war crimes, severe cases of child pornography, or any three felonies in case of three-strikes law. Life imprisonment can also be imposed, in certain countries, for traffic offences causing death. Life imprisonment is not used in all countries; Portugal was the first country to abolish life imprisonment, in 1884.
A crime of passion, in popular usage, refers to a violent crime, especially homicide, in which the perpetrator commits the act against someone because of sudden strong impulse such as anger or jealousy rather than as a premeditated crime. A high level of social and legal acceptance of crimes of passion has been historically associated with France from the 19th century to the 1970s, and until recently with Latin America.
In common law jurisdictions, an acquittal certifies that the accused is free from the charge of an offense, as far as criminal law is concerned. The finality of an acquittal is dependent on the jurisdiction. In some countries, such as the United States, an acquittal prohibits the retrial of the accused for the same offense, even if new evidence surfaces that further implicates the accused. The effect of an acquittal on criminal proceedings is the same whether it results from a jury verdict or results from the operation of some other rule that discharges the accused. In other countries, the prosecuting authority may appeal an acquittal similar to how a defendant may appeal a conviction.
Femicide or feminicide is a hate crime which is broadly defined as "the intentional killing of women or girls because they are female," but definitions of it vary depending on cultural context. In 1976, the feminist author Diana E. H. Russell first defined the term as "the killing of females by males because they are female." In some Central American countries the term femicide is used in reference to the violent killings of women and girls which are frequently perpetrated by gang members in order to stoke fear and compliance among civilians.
Gay-friendly or LGBT-friendly places, policies, people, or institutions are those that are open and welcoming to gay or LGBT people. They typically aim to create an environment that is supportive, respectful, and non-judgmental towards the LGBT community. The term "gay-friendly" originated in the late 20th century in North America, as a byproduct of a gradual implementation of gay rights, greater acceptance of LGBT people in society, and the recognition of LGBT people as a distinct consumer group for businesses.
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.
Capital punishment is a legal penalty in Pakistan. Although there have been numerous amendments to the Constitution, there is yet to be a provision prohibiting the death penalty as a punitive remedy.
An honor killing, honour killing, or shame killing is the murder of an individual, either an outsider or a member of a family, by someone seeking to protect what they see as the dignity and honor of themselves or their family. Honor killings are often connected to religion, caste and other forms of hierarchical social stratification, or to sexuality. Most often, it involves the murder of a woman or girl by male family members, due to the perpetrators' belief that the victim has brought dishonor or shame upon the family name, reputation or prestige. Honor killings are believed to have originated from tribal customs. They are prevalent in various parts of the world, as well as in immigrant communities in countries which do not otherwise have societal norms that encourage honor killings. Honor killings are often associated with rural and tribal areas, but they occur in urban areas too.
In the United States, the law for murder varies by jurisdiction. In many 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 and, in a few states, third-degree murder, followed by voluntary manslaughter and involuntary manslaughter which are not as serious, followed by reckless homicide and negligent homicide which are the least 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.
Ex parte Crow Dog, 109 U.S. 556 (1883), is a landmark decision of the Supreme Court of the United States that followed the death of one member of a Native American tribe at the hands of another on reservation land. Crow Dog was a member of the Brulé band of the Lakota Sioux. On August 5, 1881 he shot and killed Spotted Tail, a Lakota chief; there are different accounts of the background to the killing. The tribal council dealt with the incident according to Sioux tradition, and Crow Dog paid restitution to the dead man's family. However, the U.S. authorities then prosecuted Crow Dog for murder in a federal court. He was found guilty and sentenced to hang.
Capital punishment in Montenegro was first prescribed by law in 1798. It was abolished on 19 June 2002. The last execution, by shooting, took place on 29 January 1981, and the two last death sentences were pronounced on 11 October 2001. Montenegro is bound by the following international conventions prohibiting capital punishment : Second Optional Protocol to the International Covenant on Civil and Political Rights, as well as Protocols No. 6 and No. 13 to the European Convention on Human Rights. According to Art. 26 of the Montenegrin Constitution (2007): „In Montenegro, capital punishment is forbidden”.
