Mississippi Constitution Art. 3, § 27

No person shall, for any indictable offense, be proceeded against criminally by information, except in cases arising in the land or naval forces, or the military when in actual service, or by leave of the court for misdemeanor in office or where a defendant represented by counsel by sworn statement waives indictment; but the legislature, in cases not punishable by death or by imprisonment in the penitentiary, may dispense with the inquest of the grand jury, and may authorize prosecutions before justice court judges, or such other inferior court or courts as may be established, and the proceedings in such cases shall be regulated by law.
