In United States law, an Alford plea, also called a Kennedy plea in West Virginia, an Alford guilty plea, and the Alford doctrine, is a guilty plea in criminal court, whereby a defendant in a criminal case does not admit to the criminal act and asserts innocence, but admits that the evidence presented by the prosecution would be likely to persuade a judge or jury to find the defendant guilty beyond a reasonable doubt. This can be caused by circumstantial evidence and testimony favoring the prosecution and difficulty finding evidence and witnesses that would aid the defense.
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 an episodic 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 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.
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 plea bargain is an agreement in criminal law proceedings, whereby the prosecutor provides a concession to the defendant in exchange for a plea of guilt or nolo contendere. This may mean that the defendant will plead guilty to a less serious charge, or to one of the several charges, in return for the dismissal of other charges; or it may mean that the defendant will plead guilty to the original criminal charge in return for a more lenient sentence.
The gay panic defense or homosexual advance defence is a legal strategy in which a defendant claims to have acted in a state of violent, temporary insanity, committing assault or murder, because of unwanted same-sex sexual advances, usually between men. 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.
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.
An inchoate offense, preliminary crime, inchoate crime or incomplete crime is a crime of preparing for or seeking to commit another crime. The most common example of an inchoate offense is "attempt". "Inchoate offense" has been defined as the following: "Conduct deemed criminal without actual harm being done, provided that the harm that would have occurred is one the law tries to prevent."
The urban survival syndrome, in United States jurisprudence, can be used either as a defense of justification or of excuse. The first case using, unsuccessfully, the defense of "urban survival syndrome" is the 1994 Fort Worth, Texas murder trial of Daimion Osby.
An attempt to commit a crime occurs if a criminal has an intent to commit a crime and takes a substantial step toward completing the crime, but for reasons not intended by the criminal, the final resulting crime does not occur. Attempt to commit a particular crime is a crime, usually considered to be of the same or lesser gravity as the particular crime attempted. Attempt is a type of inchoate crime, a crime that is not fully developed. The crime of attempt has two elements, intent and some conduct toward completion of the crime.
John Arthur Spenkelink was an American convicted murderer. He was executed in 1979, the first convicted criminal to be executed in Florida after capital punishment was reinstated in 1976, and the second in the United States.
Voluntary manslaughter is the killing of a human being in which the offender acted during the heat of passion, under circumstances that would cause a reasonable person to become emotionally or mentally disturbed to the point that they cannot reasonably control their emotions. Voluntary manslaughter is one of two main types of manslaughter, the other being involuntary manslaughter.
Philip Ray Workman was a death row inmate executed in Tennessee on May 9, 2007. He was convicted in 1982 for the murder of a police officer following a robbery of a Wendy's restaurant in Memphis, Tennessee, and sentenced to death by lethal injection.
In the United States criminal justice system, a competency evaluation is an assessment of the ability of a defendant to understand and rationally participate in a court process.
Frendak v. United States, 408 A.2d 364 is a landmark case in which District of Columbia Court of Appeals decided that a judge could not impose an insanity defense over the defendant's objections.
State v. Mitchell, 170 Mo. 633, 71 S.W. 175 (1902), is a precedent-setting decision of the Supreme Court of Missouri which is part of the body of case law involving the prosecution of failed attempts to commit a crime. In United States law, cases involving failed criminal attempts can bring up interesting legal issues of whether the crime was unsuccessful due to factual impossibility or to legal impossibility.
United States v. Thomas 13 U.S.C.M.A. 278 (1962) is a famous case of a military court-martial involving a failed attempt to commit a crime, in this case, rape and the use of the "impossibility" defense.
People v. Lee Kong, 95 Cal. 666 (1892), is a case in which the defendant claimed the "impossibility" defense to charges of assault, on the basis of a mistake in fact. The ultimate issue in this case is whether the defendant's actions and intent warrant criminal sanctions even though he failed to achieve a criminal act because the act itself was factually impossible to commit.
An impossibility defense is a criminal defense occasionally used when a defendant is accused of a criminal attempt that failed only because the crime was factually or legally impossible to commit. Factual impossibility is rarely an adequate defense at common law. This is not to be confused with a 'mistake of fact' defence, which may be a defence to a specific intent crime like larceny.
Responsibility for criminal law and criminal justice in the United States is shared between the states and the federal government.
Kahler v. Kansas, 589 U.S. ___ (2020), is a case of the United States Supreme Court in which the justices ruled that the Eighth and Fourteenth Amendments of the United States Constitution do not require that states adopt the insanity defense in criminal cases that are based on the defendant's ability to recognize right from wrong. It was argued on October 7, 2019 and decided on March 23, 2020.
