Final answer:
It is false that the Mississippi Constitution guarantees the right to a grand jury presentation; states are not required to use grand juries but must provide an equally fair process, which may include a preliminary hearing.
Step-by-step explanation:
The statement that the Mississippi Constitution guarantees an accused the right to have his/her case presented to a grand jury is false. The Fifth Amendment of the United States Constitution does require a grand jury indictment for federal felony charges, but states are not mandated to use grand juries. Instead, states must provide an equally fair process, which may include a preliminary hearing by a judge instead of a grand jury proceeding. Additionally, in the state courts, the right to a speedy and public trial, the right to an impartial jury, and the right to counsel among others are protected by the Sixth Amendment.
