2021 Louisiana Laws|Revised Statutes|Title 32 - Motor Vehicles and Traffic Regulation|§6. Authority of Department of Public Safety and Corrections to serve notices and subpoenas; procedure

RS 6 - Authority of Department of Public Safety and Corrections to serve notices and subpoenas; procedure A. In administering laws and regulations under Title 32, unless otherwise provided, the Department of Public Safety and Corrections may serve notices and subpoenas by domiciliary service, personal service, or United States mail as provided in Subsection B of this Section. Personal service is made when a process server tenders the notice or subpoena to the addressee. Domiciliary service is made when a process server leaves the notice or subpoena at the dwelling house or usual abode of the addressee with a person of suitable age and discretion residing therein as a member of the domiciliary establishment of the addressee.  B.(1) The department may serve all notices and subpoenas by mailing the same in the United States Post Office, by either certified mail, return receipt requested, or first-class mail to the addressee at the address most recently furnished to the department.  (2) Service by first-class mail shall include a request that the enclosed return form be signed by the addressee and mailed to the department. If a signed return is not received by the department within fifteen days after mailing, the notice or subpoena shall be served by domiciliary or personal service as provided in Subsection A of this Section. (3) Service by mail shall be considered personal service if the certified return receipt or the return form is signed by the addressee. Service by mail shall be considered domiciliary service if the certified return receipt or the return form is signed by anyone other than the addressee.  C. The department may make service of notices or subpoenas on law enforcement officers through the law enforcement officer's ranking officers or their designated representative, which, upon service thereof, shall have the same legal effect as if domiciliary service had been made upon the law enforcement officer named therein. This service shall be made at the appropriate troop, region, or departmental headquarters of the law enforcement agency. Service may consist of individual notices or subpoenas or may consist of lists which include the officer's name and badge number, case title, and date of commanded appearance. Such lists may be served by the department by means of electronic transfer to printing devices located at the troop, region, or departmental headquarters. The ranking officer, or his designated representative, shall sign for such notices or subpoenas or indicate receipt by electronic verification code, and shall be required to notify the law enforcement officer named therein of receipt of the subpoenas or list. This type of service shall be known as departmental service on law enforcement officers, and shall not be construed to replace domiciliary or personal service on them but shall be an additional method of service.  D. For purposes of this Section: (1) "Addressee" means the individual to whom the subpoena is directed.  (2) "Process server" means any person otherwise authorized by law to serve process, and shall also mean a chief process server or one of his deputies, which chief process server and as many deputy process servers as necessary shall be appointed by the department.  (3) "Subpoena" includes a subpoena issued for the attendance of an individual and a subpoena duces tecum.  Acts 1990, No. 319, §1.
