Criminal trial in the context of "Legal case"

Legal proceeding is an activity that seeks to invoke the power of a tribunal in order to enforce a law. Although the term may be defined more broadly or more narrowly as circumstances require, it has been noted that "[t]he term legal proceedings includes proceedings brought by or at the instigation of a public authority, and an appeal against the decision of a court or tribunal". Legal proceedings are generally characterized by an orderly process in which participants or their representatives are able to present evidence in support of their claims, and to argue in favor of particular interpretations of the law, after which a judge, jury, or other trier of fact makes a determination of the factual and legal issues.

• Activities needed to have a court deem legal process to have been provided, such as through service of process.
• Conduct of a trial, whether a lawsuit or civil trial, or a criminal trial.
• Issuance and enforcement of court orders, including those imposing foreclosure or receivership.
• Hearings, particularly administrative hearings.
• Arbitration.

In the United States, Congressional hearings are not generally considered legal proceedings, as they are generally not directed towards the imposition of a penalty against a specific individual for a specific wrong. However, impeachment proceedings are generally conducted as legal proceedings, although experts dispute the question of whether they are primarily legal proceedings, or are merely political proceedings dressed in legal formalities and language. Richard Posner, for example, has asserted that it was "the intent of the framers of the Constitution that an impeachment proceeding be primarily a legal proceeding, akin to a criminal prosecution, rather than a political one".

Criminal investigation is an applied science that involves the study of facts that are then used to inform criminal trials. A complete criminal investigation can include searching, interviews, interrogations, evidence collection and preservation, and various methods of investigation. Modern-day criminal investigations commonly employ many modern scientific techniques known collectively as forensic science.

Criminal investigation is an ancient science that may have roots as far back as c. 1700 BCE in the writings of the Code of Hammurabi. In the code, it is suggested that both the accuser and the accused had the right to present evidence they collected. In the modern era, criminals investigations are most often done by government police forces. Private investigators are also commonly hired to complete or assist in criminal investigations.

A prosecutor is a legal representative of the prosecution in states with either the adversarial system, which is adopted in common law, or inquisitorial system, which is adopted in civil law. The prosecution is the legal party responsible for presenting the case in a criminal trial against the defendant, an individual accused of breaking the law. Typically, the prosecutor represents the state or the government in the case brought against the accused person.

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 (a judge or a jury). 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.

In many countries and under many legal systems, including common law and civil law systems (not to be confused with the other kind of civil law, which deals with non-criminal legal issues), the presumption of innocence is a legal right of the accused in a criminal trial. It is also an international human right under the UN's Universal Declaration of Human Rights, Article 11.
