Mississippi Code Title 99. Criminal Procedure § 99-15-55

If, on the examination into the case of any person brought before a conservator of the peace other than a justice of the peace, on a charge of felony, it shall clearly appear that a felony has not been committed, but that the accused is guilty of a misdemeanor of which a justice of the peace has jurisdiction, the conservator of the peace shall require the accused to be carried before the proper justice of the peace for trial. If the conservator of the peace in such case be a justice of the peace, having territorial jurisdiction of the offense he shall convict the offender and punish him accordingly, but such conviction shall not bar a subsequent prosecution for felony in the same matter.
