Lanagan DUI-DWI Lawyer, Missouri

One of the most sacred principles in the American criminal justice system, holding that a defendant is innocent until proven guilty. In other words, the prosecution must prove, beyond a reasonable doubt, each element of the crime charged.

A minor violation of the law that is punishable only by a fine--for example, a traffic or parking ticket. Not all vehicle-related violations are infractions, however--refusing to identify oneself when involved in an accident is a misdemeanor in some states.

A seldom-used test for criminal insanity that labels the person insane if he could not control his actions when committing the crime, even though he knew his actions were wrong.

The privilege that allows the president and other high officials of the executive branch to keep certain communications private if disclosing those communications would disrupt the functions or decisionmaking processes of the executive branch. As demonstrated by the Watergate hearings, this privilege does not extend to information germane to a criminal investigation.

Latin for 'we shall no longer prosecute.' At trial, this is an entry made on the record by a prosecutor in a criminal case stating that he will no longer pursue the matter. An entry of nolle prosequi may be made at any time after charges are brought and before a verdict is returned or a plea entered. Essentially, it is an admission on the part of the prosecution that some aspect of its case against the defendant has fallen apart. Most of the time, prosecutors need a judge's A1:C576 to 'nol-pros' a case. (See Federal Rule of Criminal Procedure 48a.) Abbreviated 'nol. pros.' or 'nol-pros.'

A party's job of convincing the decisionmaker in a trial that the party's version of the facts is true. In a civil trial, it means that the plaintiff must convince the judge or jury 'by a preponderance of the evidence' that the plaintiff's version is true -- that is, over 50% of the believable evidence is in the plaintiff's favor. In a criminal case, because a person's liberty is at stake, the government has a harder job, and must convince the judge or jury beyond a reasonable doubt that the defendant is guilty.

The money paid to the court, usually at arraignment or shortly thereafter, to ensure that an arrested person who is released from jail will show up at all required court appearances. The amount of bail is determined by the local bail schedule, which is based on the seriousness of the offense. The judge can increase the bail if the prosecutor convinces him that the defendant is likely to flee (for example, if he has failed to show up in court in the past), or he can decrease it if the defense attorney shows that the defendant is unlikely to run (for example, he has strong ties to the community by way of a steady job and a family).

Latin for 'You have the body.' A prisoner files a petition for writ of habeas corpus in order to challenge the authority of the prison or jail warden to continue to hold him. If the judge orders a hearing after reading the writ, the prisoner gets to argue that his confinement is illegal. These writs are frequently filed by convicted prisoners who challenge their conviction on the grounds that the trial attorney failed to prepare the defense and was incompetent. Prisoners sentenced to death also file habeas petitions challenging the constitutionality of the state death penalty law. Habeas writs are different from and do not replace appeals, which are arguments for reversal of a conviction based on claims that the judge conducted the trial improperly. Often, convicted prisoners file both.

A court official usually classified as a peace officer (sometimes as a deputy sheriff, or marshal) and usually wearing a uniform. A bailiff's main job is to maintain order in the courtroom. In addition, bailiffs often help court proceedings go smoothly by shepherding witnesses in and out of the courtroom and handing evidence to witnesses as they testify. In criminal cases, the bailiff may have temporary charge of any defendant who is in custody during court proceedings.
