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. The double jeopardy protection in criminal prosecutions only bars an identical prosecution for the same offence, however, a different offence may be charged on identical evidence at a second trial. Res judicata protection is stronger – it precludes any causes of action or claims that arise from a previously litigated subject matter.
A felony is traditionally considered a crime of high seriousness, whereas a misdemeanor is regarded as less serious. The term "felony" originated from English common law to describe an offense that resulted in the confiscation of a convicted person's land and goods, to which additional punishments, including capital punishment, could be added; other crimes were called misdemeanors. Following conviction of a felony in a court of law, a person may be described as a felon or a convicted felon.
A jury trial, or trial by jury, is a legal proceeding in which a jury makes a decision or findings of fact. It is distinguished from a bench trial in which a judge or panel of judges makes all decisions.
A misdemeanor is any "lesser" criminal act in some common law legal systems. Misdemeanors are generally punished less severely than more serious felonies, but theoretically more so than administrative infractions and regulatory offences. Typically, misdemeanors are punished with prison time of no longer than one year, monetary fines, or community service.
A summary offence or petty offence is a violation in some common law jurisdictions that can be proceeded against summarily, without the right to a jury trial and/or indictment.
In criminal law, the intoxication defense is a defense by which a defendant may claim diminished responsibility on the basis of substance intoxication. Where a crime requires a certain mental state to break the law, those under the influence of an intoxicating substance may be considered to have reduced liability for their actions. With regard to punishment, intoxication may be a mitigating factor that decreases a prison or jail sentence. Numerous factors affect the applicability of the defense.
The rule of felony murder is a legal doctrine in some common law jurisdictions that broadens the crime of murder: when someone is killed in the commission of a dangerous or enumerated crime, the offender, and also the offender's accomplices or co-conspirators, may be found guilty of murder.
Attempted murder is a crime of attempt in various jurisdictions.
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."
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.
In France, a cour d'assises, or Court of Assizes or Assize Court, is a criminal trial court with original and appellate limited jurisdiction to hear cases involving defendants accused of felonies, meaning crimes as defined in French law. It is the only French court that uses a jury trial.
Taylor v. United States, 495 U.S. 575 (1990), was a U.S. Supreme Court decision that filled in an important gap in the federal criminal law of sentencing. The federal criminal code does not contain a definition of many crimes, including burglary, the crime at issue in this case. Yet sentencing enhancements applicable to federal crimes allow for the enhancement of a defendant's sentence if he has been convicted of prior felonies. The Court addressed in this case how "burglary" should be defined for purposes of such sentencing enhancements when the federal criminal code contained no definition of "burglary." The approach the Court adopted in this case has guided the lower federal courts in interpreting other provisions of the criminal code that also refer to generic crimes not otherwise defined in federal law.
James v. United States, 550 U.S. 192 (2007), is a decision by the Supreme Court of the United States that held that attempted burglary could serve as a predicate felony under the federal Armed Career Criminal Act (ACCA), which provided that a person convicted of being a felon in possession of a firearm with three prior convictions for either serious drug offenses or violent felonies must be sentenced to a mandatory minimum 15-year prison term.
Fault, as a legal term, refers to legal blameworthiness and responsibility in each area of law. It refers to both the actus reus and the mental state of the defendant. The basic principle is that a defendant should be able to contemplate the harm that his actions may cause, and therefore should aim to avoid such actions. Different forms of liability employ different notions of fault, in some there is no need to prove fault, but the absence of it.
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:
The Armed Career Criminal Act of 1984 (ACCA) is a United States federal law that provides sentence enhancements for felons who commit crimes with firearms if they are convicted of certain crimes three or more times. Pennsylvania Senator Arlen Specter was a key proponent for the legislation.
Aiding and abetting is a legal doctrine related to the guilt of someone who aids or abets another person in the commission of a crime. It exists in a number of different countries and generally allows a court to pronounce someone guilty for aiding and abetting in a crime even if he or she is not the principal offender. The words aiding, abetting and accessory are closely used but have differences. While aiding means providing support or assistance to someone, abetting means encouraging someone else to commit a crime. Accessory is someone who in fact assists "commission of a crime committed primarily by someone else". However, some jurisdictions have merged being an accessory before the fact with aiding and abetting.
The criminal law of the United States is a manifold system of laws and practices that connects crimes and consequences. In comparison, civil law addresses non-criminal disputes. The system varies considerably by jurisdiction, but conforms to the US Constitution.
Schmuck v. United States, 489 U.S. 705 (1989), is a United States Supreme Court decision on criminal law and procedure. By a 5–4 margin it upheld the mail fraud conviction of an Illinois man and resolved a conflict among the appellate circuits over which test to use to determine if a defendant was entitled to a jury instruction allowing conviction on a lesser included charge. Justice Harry Blackmun wrote for the majority; Antonin Scalia for the dissent.
Carter v. United States, 530 U.S. 255, is a United States Supreme Court case in which the Court held, 5–4, that a defendant charged with robbery under 18 USC § 2113(a) was not entitled to a jury instruction to consider the lesser offense of larceny under 18 USC § 2113(b).
