The material published contains information about the application of the contravention sanctions by the court - the arrest, as an exceptional punishment. The proposed study reveals the definition, particularities and conditions of the arrest application in terms of the principle of freedom, expressed both in national and international norms. At the same time, the cases and categories of persons are highlighted to whom the contravention arrest cannot be applied, as well as the exception of unconstitutionality for some causes. An important part of the work is the procedure and the conditions set by the legislator for the execution of the arrest sanction, as well as the national statistics on the number of the contraveners for whom the arrest was applied.
