Mississippi Code Title 99. Criminal Procedure § 99-3-47

(1) An application for a felony warrant or signature utilized by the judicial branch of state government other than an application for a no-knock warrant shall not be denied legal effect or enforceability solely because it is in electronic form. An application, signature or record in electronic form shall have the full effect of law.

(2) If a provision of law requires the application for a felony warrant to be in writing, an electronic version of the written record shall satisfy such provision of law.

(3) If a provision of law requires a signature, an electronic signature satisfies such provision of law.

(4) An application used to attach a digital signature to a felony warrant or affidavit must have security procedures in place that ensure the authenticity of the digital signature. The application must also be able to keep an electronic record of the warrant or affidavit, including the time and date of when the signature was attached. The application must also include encryption measures to ensure secure access of the application.

(5) Unless otherwise agreed to by a sender of a warrant application and the judge, an electronic record is received when:

(6) In an instance where an affidavit is submitted to a judge electronically, the electronic signature of the affiant shall satisfy the constitutional requirement that the testimony of the affiant be made under oath, provided that such signature is made under penalty of perjury and in compliance with subsection (4) of this section. If the requirements of subsection (4) of this section are met, it shall not be necessary for the oath to be made orally for the affidavit to have legal effect.

(7) An application for a felony warrant or signature made pursuant to this section shall contain a statement that the application is being made for a felony criminal investigation.

(8) Before an electronic felony warrant shall be issued pursuant to this section, the applicant shall be required to meet with a judge. The meeting required by this subsection may be through the use of video or teleconference devices.

(9) This section shall not authorize the issuance of no-knock warrants by the use of electronic warrant applications or electronic signatures for the applications.
