Administrative detention refers to a kind of administrative punishment that legal administrative organs (especially public security organs) restrict personal freedom in a short time for those who violate administrative legal norms according to law. Administrative detention is the most severe administrative punishment, which is usually applied to acts that seriously violate public security management but do not constitute a crime. Warnings and fines are not enough to punish. Therefore, the law has strict regulations on its establishment, implementation conditions and procedures. The decision-making power of administrative detention belongs to the public security organs at or above the county level; The time limit is generally within 10 day, and the heavier one does not exceed 15 day; After the announcement of the administrative detention decision, during the application for reconsideration and administrative litigation, if the punished person and his relatives find a guarantor or pay a deposit in accordance with the regulations, they may apply to the administrative subject for suspending the execution of administrative detention.
