Executive Magistrates are appointed by state governments and have administrative and executive powers under criminal law, in contrast to judicial magistrates who are part of the judiciary. Some key powers of executive magistrates include issuing search warrants, preventing public nuisances, dispersing unlawful assemblies, holding inquests of unnatural deaths, and taking security from arrested persons for their attendance in court. They are subordinate to district and sub-divisional magistrates and do not directly exercise arrest powers but through the police.
