The mission of the Hidalgo County Constable Precinct 3 Department is to be responsive to the community in the delivery of quality services; to maintain order while affording dignity and respect to every individual; and improve the quality of life through a community partnership that promotes safe and secure neighborhoods.

The Constable and his deputies have all the powers and responsibilities of any peace officer of the State. They may write traffic citations, make arrests, conduct criminal investigations and file criminal charges. The Constable and his deputies serve as Bailiffs in the Justice Court. They are responsible for serving and executing Civil Process and Civil Court Orders. Because civil law is often more technical than criminal law, additional training in specialized schools is required for all Deputy Constables and Administrative staff.
