The right of trial by jury shall be and remain inviolate, except in civil cases wherein the amount in controversy does not exceed One Thousand Five Hundred Dollars ($1,500.00), or in criminal cases wherein punishment for the offense charged is by fine only, not exceeding One Thousand Five Hundred Dollars ($1,500.00). Provided, however, that the Legislature may provide for jury trial in cases involving lesser amounts. Juries for the trial of civil cases, involving more than Ten Thousand Dollars ($10,000.00), and felony criminal cases shall consist of twelve (12) persons. All other juries shall consist of six (6) persons. However, in all cases the parties may agree on a lesser number of jurors than provided herein.
In all criminal cases where imprisonment for more than six (6) months is authorized the entire number of jurors must concur to render a verdict. In all other cases three-fourths (3/4) of the whole number of jurors concurring shall have power to render a verdict. When a verdict is rendered by less than the whole number of jurors, the verdict shall be signed by each juror concurring therein.
