The principle of in dubio pro reo (Latin for "[when] in doubt, rule for the accused") [1] [2] means that a defendant may not be convicted by the court when doubts about their guilt remain.
The rule of lenity is the doctrine that ambiguity should be resolved in favor of the more lenient punishment. [3]
To resolve all doubts in favor of the accused is in consonance with the principle of presumption of innocence. [3]
The main principle in the sentence was part of Aristotle's interpretation of the law and shaped the Roman law: Favorabiliores rei potius quam actores habentur ( Digest of Justinian I, D.50.17.125), [4] meaning "The condition of the defendant is to be favored rather than that of the plaintiff." [5] However, the phrase was not spelled out word for word until the Milanese jurist Egidio Bossi (1487–1546) related it in his treatises.
In German law, the principle is not normalized but has constitutional status and is derived from Article 103(2) of the Basic Law, Article 6 of the ECHR, and Section 261 of the Code of Criminal Procedure. The common use of the phrase in the German legal tradition was documented in 1631 by Friedrich Spee von Langenfeld.
In Canadian law, the leading case establishing how to decide criminal cases where the guilt of the accused depends on contradictory witness accounts is R. v. W.(D.) (1991).
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.
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.
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 or persistent 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.
A jury trial, or trial by jury, is a lawful 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 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 Sixth Amendment to the United States Constitution sets forth rights related to criminal prosecutions. It was ratified in 1791 as part of the United States Bill of Rights. The Supreme Court has applied the protections of this amendment to the states through the Due Process Clause of the Fourteenth Amendment.
Criminal procedure is the adjudication process of the criminal law. While criminal procedure differs dramatically by jurisdiction, the process generally begins with a formal criminal charge with the person on trial either being free on bail or incarcerated, and results in the conviction or acquittal of the defendant. Criminal procedure can be either in form of inquisitorial or adversarial criminal procedure.
Burden of proof is a legal duty that encompasses two connected but separate ideas that apply for establishing the truth of facts in a trial before tribunals in the United States: the "burden of production" and the "burden of persuasion." In a legal dispute, one party is initially presumed to be correct, while the other side bears the burden of producing evidence persuasive enough to establish the truth of facts needed to satisfy all the required legal elements of the dispute. There are varying types of burden of persuasion commonly referred to as standards of proof, and depending on the type of case, the standard of proof will be higher or lower. Burdens of persuasion and production may be of different standards for each party, in different phases of litigation. The burden of production is a minimal burden to produce at least enough evidence for the trier of fact to consider a disputed claim. After litigants have met the burden of production, they have the burden of persuasion: that enough evidence has been presented to persuade the trier of fact that their side is correct. There are different standards of persuasiveness ranging from a preponderance of the evidence, where there is just enough evidence to tip the balance, to proof beyond a reasonable doubt, as in United States criminal courts.
Civil procedure is the body of law that sets out the rules and standards that courts follow when adjudicating civil lawsuits. These rules govern how a lawsuit or case may be commenced; what kind of service of process is required; the types of pleadings or statements of case, motions or applications, and orders allowed in civil cases; the timing and manner of depositions and discovery or disclosure; the conduct of trials; the process for judgment; the process for post-trial procedures; various available remedies; and how the courts and clerks must function.
An inquisitorial system is a legal system in which the court, or a part of the court, is actively involved in investigating the facts of the case. This is distinct from an adversarial system, in which the role of the court is primarily that of an impartial referee between the prosecution and the defense. Inquisitorial systems are used primarily in countries with civil legal systems, such as France and Italy, or legal systems based on Islamic law like Saudi Arabia, rather than in common law systems. It is the prevalent legal system in Continental Europe, Latin America, African countries not formerly under British rule, East Asia, Indochina, Thailand, the Philippines, and Indonesia. Most countries with an inquisitorial system also have some form of civil code as their main source of law.
Corpus delicti, in Western law, is the principle that a crime must be proved to have occurred before a person can be convicted of committing that crime.
The presumption of innocence is a legal principle that every person accused of any crime is considered innocent until proven guilty. Under the presumption of innocence, the legal burden of proof is thus on the prosecution, which must present compelling evidence to the trier of fact. If the prosecution does not prove the charges true, then the person is acquitted of the charges. The prosecution must in most cases prove that the accused is guilty beyond a reasonable doubt. If reasonable doubt remains, the accused must be acquitted. The opposite system is a presumption of guilt.
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 balance of probabilities and is usually therefore reserved for criminal matters where what is at stake is considered more serious and therefore deserving of a higher threshold.
Exculpatory evidence is evidence favorable to the defendant in a criminal trial that exonerates or tends to exonerate the defendant of guilt. It is the opposite of inculpatory evidence, which tends to present guilt.
In law, a trial is a coming together of parties to a dispute, to present information in a tribunal, a formal setting with the authority to adjudicate claims or disputes. One form of tribunal is a court. The tribunal, which may occur before a judge, jury, or other designated trier of fact, aims to achieve a resolution to their dispute.
Actual innocence is a special standard of review in legal cases to prove that a charged defendant did not commit the crimes that they were accused of, which is often applied by appellate courts to prevent a miscarriage of justice.
In law, ignorantia juris non excusat, or ignorantia legis neminem excusat, is a legal principle holding that a person who is unaware of a law may not escape liability for violating that law merely by being unaware of its content.
Estelle v. Williams, 425 U.S. 501 (1976), is a Supreme Court case involving Harry Lee Williams' conviction of assault on his former landlord in Harris County, Texas. While awaiting trial Williams was unable to post bail. He was tried in his prison uniform, and later was found guilty. He sought a writ of habeas corpus saying being tried in a prison uniform violated his Constitutional rights in accordance with the 14th Amendment. The Court of Appeals ruled that the accused does not have to stand trial in identifiable prison clothes and Williams’ right to due process was violated. The Supreme Court reversed, reinstating the conviction, on June 21, 1976.
The rule of lenity, also called the rule of strict construction, is a principle of criminal statutory interpretation that requires a court to apply any unclear or ambiguous law in the manner that is most favorable to the defendant. The rule has a long history in the law and has been an important element of the relationship between the courts and the legislature, but its role in modern jurisprudence is less clear.
The Staatsanwaltschaft, is the public prosecutor's office in Germany. They are the offices of the public prosecutors which are criminal justice bodies attached to the judiciary but separate from the courts.
