Mandatory sentencing
（重定向自Mandatory sentence）
A mandatory sentence is a court decision setting where judicial discretion is limited by law. Typically, people convicted of certain crimes must be punished with at least a minimum number of years in prison. Mandatory sentencing laws vary from country to country; it is mainly an area of interest only in common law jurisdictions since civil law jurisdictions usually prescribe minimum and maximum sentences for every type of crime in explicit laws.
