Typically, a jury must come to a unanimous decision before it delivers a verdict; however, there are exceptions. When a jury does not reach a unanimous decision and does not feel it is possible to do so, they declare themselves a "hung jury", a mistrial is declared, and the trial will have to be redone at the discretion of the plaintiff or prosecutor.
