when can a case be heard only by a judge
Jury trial Some jurisdictions with jury trials allow the defendant to waive their right to a jury trial, thus leading to a bench trial. Jury trials tend to occur only when a crime is considered serious. In some jurisdictions, such as France and Brazil, jury trials are reserved, and compulsory, for the most severe crimes and are not available for civil cases. In Brazil, for example, trials by jury are applied in cases of voluntary crimes against life, such as first and second degree murder, forced abortion and instigation of suicide, even if only attempted. In others, such as the United Kingdom, jury trials are only available for criminal cases and very specific civil cases (defamation, malicious prosecution, civil fraud and false imprisonment). In the United States, jury trials are available in both civil and criminal cases. In Canada, an individual charged with an indictable offence may elect to be tried by a judge alone in a provincial court, by judge alone in a superior court, or by judge and jury in a superior court; summary offences cannot be tried by jury.
