Mens rea in the context of "Specific intent"

Murder is the unlawful killing of another human without justification or valid excuse committed with the necessary intention as defined by the law in a specific jurisdiction. 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, such as in the case of voluntary manslaughter 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.

Most societies consider murder to be an extremely serious crime, and thus believe that a person convicted of murder should receive harsh punishments for the purposes of retribution, deterrence, rehabilitation, or incapacitation. In most countries, a person convicted of murder generally receives a long-term prison sentence, a life sentence, or capital punishment. Some countries, states, and territories, including the United Kingdom and other countries with English-derived common law, mandate life imprisonment for murder, whether it is subdivided into first-degree murder or otherwise.

A debtors' prison is a prison for people who are unable to pay debt. Until the mid-19th century, debtors' prisons (usually similar in form to locked workhouses) were a common way to deal with unpaid debt in Western Europe. Destitute people who were unable to pay a court-ordered judgment would be incarcerated in these prisons until they had worked off their debt via labour or secured outside funds to pay the balance. The product of their labour went towards both the costs of their incarceration and their accrued debt. Increasing access and lenience throughout the history of bankruptcy law have made prison terms for unaggravated indigence obsolete over most of the world.

Since the late 20th century, the term debtors' prison has also sometimes been applied by critics to criminal justice systems in which a court can sentence someone to prison over willfully unpaid criminal fees, usually following the order of a judge. For example, in some jurisdictions within the United States, people can be held in contempt of court and jailed after willful non-payment of child support, garnishments, confiscations, fines, or back taxes. Additionally, though properly served civil duties over private debts in nations such as the United States will merely result in a default judgment being rendered in absentia if the defendant willfully declines to appear by law, a substantial number of indigent debtors are legally incarcerated for the crime of failing to appear at civil debt proceedings as ordered by a judge. In this case, the crime is not indigence, but disobeying the judge's order to appear before the court. Critics argue that the "willful" terminology is subject to individual mens rea determination by a judge, rather than statute, and that since this presents the potential for judges to incarcerate legitimately indigent individuals, it amounts to a de facto "debtors' prison" system.

Genocidal intent is the specific mental element, or mens rea, required to classify an act as genocide under international law, particularly the 1948 Genocide Convention. To establish genocide, perpetrators must be shown to have had the dolus specialis, or specific intent, to destroy a particular national, ethnic, racial, or religious group, in whole or in part. Unlike broader war crimes or crimes against humanity, genocidal intent necessitates a deliberate aim to eliminate the targeted group rather than merely displace or harm its members.

The concept of genocidal intent is complex and has spurred significant legal debate, primarily due to the challenge of proving an individual’s intent to destroy a group without direct evidence. International criminal tribunals, such as those for Rwanda and the former Yugoslavia, have relied on circumstantial evidence to infer intent, considering the scale, systematic nature, and targeting patterns of atrocities. Legal standards for genocidal intent have varied, with some rulings demanding dolus directus (direct intent to cause harm) and others allowing for dolus indirectus (foreseeable consequences accepted by the perpetrator). This discrepancy has influenced judicial outcomes, as seen in the acquittal of certain defendants under stringent intent requirements, leading some scholars to advocate for a knowledge-based standard to better facilitate genocide convictions.

Forgery is a white-collar crime that generally consists of the false making or material alteration of a legal instrument with the specific intent to defraud. Tampering with a certain legal instrument may be forbidden by law in some jurisdictions but such an offense is not related to forgery unless the tampered legal instrument was actually used in the course of the crime to defraud another person or entity. Copies, studio replicas, and reproductions are not considered forgeries, though they may later become forgeries through knowing and willful misrepresentations.

Forging money or currency is more often called counterfeiting. But consumer goods may also be counterfeits if they are not manufactured or produced by the designated manufacturer or producer given on the label or flagged by the trademark symbol. When the object forged is a record or document it is often called a false document.

In law, attendant circumstances (sometimes external circumstances) are the facts surrounding an event.

In criminal law in the United States, the definition of a given offense generally includes up to three kinds of "elements": the actus reus, or guilty conduct; the mens rea, or guilty mental state; and the attendant (sometimes "external") circumstances. The reason is given in Powell v. Texas, 392 U.S. 514, 533 (1968):

In criminal law, intent is a subjective state of mind (mens rea) that must accompany the acts of certain crimes to constitute a violation. A more formal, generally synonymous legal term is scienter: intent or knowledge of wrongdoing.

In criminal and civil law, strict liability is a standard of liability under which a person is legally responsible for the consequences flowing from an activity even in the absence of fault or criminal intent on the part of the defendant.

Under the strict liability law, if the defendant possesses anything that is inherently dangerous, as specified under the "ultrahazardous" definition, the defendant is then strictly liable for any damages caused by such possession, no matter how carefully the defendant is safeguarding them.

Perjury (also known as forswearing) is the intentional act of swearing a false oath or falsifying an affirmation to tell the truth, whether spoken or in writing, concerning matters material to an official proceeding.

Like most other crimes in the common law system, to be convicted of perjury one must have had the intention (mens rea) to commit the act and have actually committed the act (actus reus). Further, statements that are facts cannot be considered perjury, even if they might arguably constitute an omission, and it is not perjury to lie about matters that are immaterial to the legal proceeding. Statements that entail an interpretation of fact are not perjury because people often draw inaccurate conclusions unwittingly or make honest mistakes without the intent to deceive. Individuals may have honest but mistaken beliefs about certain facts or their recollection may be inaccurate, or may have a different perception of what is the accurate way to state the truth. In some jurisdictions, no crime has occurred when a false statement is (intentionally or unintentionally) made while under oath or subject to penalty. Instead, criminal culpability attaches only at the instant the declarant falsely asserts the truth of statements (made or to be made) that are material to the outcome of the proceeding. It is not perjury, for example, to lie about one's age except if age is a fact material to influencing the legal result, such as eligibility for old age retirement benefits or whether a person was of an age to have legal capacity.

Insanity, madness, lunacy, and craziness are behaviors caused by certain abnormal mental or behavioral patterns. Insanity can manifest as violations of societal norms, including a person or persons becoming a danger to themselves or to other people. Conceptually, mental insanity also is associated with the biological phenomenon of contagion (that mental illness is infectious) as in the case of copycat suicides. In contemporary usage, the term insanity is an informal, un-scientific term denoting "mental instability"; thus, the term insanity defense is the legal definition of mental instability. In medicine, the general term psychosis is used to include the presence of delusions and/or hallucinations in a patient; and psychiatric illness is "psychopathology", not mental insanity.

In English, the word "sane" derives from the Latin adjective sanus, meaning "healthy". Juvenal's phrase mens sana in corpore sano is often translated to mean a "healthy mind in a healthy body". From this perspective, insanity can be considered as poor health of the mind, not necessarily of the brain as an organ (although that can affect mental health), but rather refers to defective function of mental processes such as reasoning. Another Latin phrase related to our current concept of sanity is compos mentis ("sound of mind"), and a euphemistic term for insanity is non compos mentis. In law, mens rea means having had criminal intent, or a guilty mind, when the act (actus reus) was committed.
