A mistrial may be ordered, and in a jury case the jury dismissed, when:

(1)  The defendant consents thereto;

(2)  The jury is unable to agree upon a verdict;

(3)  There is a legal defect in the proceedings which would make any judgment entered upon a verdict reversible as a matter of law;

(4)  The court finds that the defendant does not have the mental capacity to proceed;

(5)  It is physically impossible to proceed with the trial in conformity with law; or

(6)  False statements of a juror on voir dire prevent a fair trial.

Upon motion of a defendant, a mistrial shall be ordered, and in a jury case the jury dismissed, when prejudicial conduct in or outside the courtroom makes it impossible for the defendant to obtain a fair trial, or when authorized by Article 770 or 771.

A mistrial shall be ordered, and in a jury case the jury dismissed, when the state and the defendant jointly move for a mistrial.
