The state and the defendant shall have the right before argument to submit to the court special written charges for the jury.  Such charges may be received by the court in its discretion after argument has begun.  The party submitting the charges shall furnish a copy of the charges to the other party when the charges are submitted to the court.

A requested special charge shall be given by the court if it does not require qualification, limitation, or explanation, and if it is wholly correct and pertinent.  It need not be given if it is included in the general charge or in another special charge to be given.
