No. The plaintiff has the burden of proof.
Under US law: There is NO burden on the accused defendant to prove anything. The entire burden of proof lies with the prosecution.
The burden of proof is on the prosecutor. They must prove beyond reasonable doubt that the accused is guilty. The defense only needs to raise reasonable doubt about the defendant's guilt. If jurors believe the defendant may have committed the crime, but have reasonable doubt then they must find the defendant not guilty.
A. shifts to the defendant
In a criminal case, the burden of proof must meet the standard of "beyond a reasonable doubt" to establish the guilt of the defendant.
The burden of proof was on the district attorney in proving the man was guilty of robbery.
"Beyond a reasonable doubt" in a criminal case, "A preponderance of the evidence" in a civil case. The advocate of a case always has the burden of proof - the prosecutor in a criminal case, the plaintiff in a civil case.
burden of proof
The term "burden of proof" in a criminal case refers to the obligation of the prosecution to prove the defendant's guilt. This standard is typically "beyond a reasonable doubt," meaning the evidence presented must leave the jury with a high degree of certainty about the defendant's guilt. The burden of proof remains with the prosecution throughout the trial, and the defendant is presumed innocent until proven guilty.
In an insanity defense, the defense must prove that the defendant is insane.
the Federal Insanity Defense Reform Act
In a misdemeanor case, the burden of proof is typically "beyond a reasonable doubt." This means that the prosecution must prove that the defendant is guilty of the crime charged to a high degree of certainty.
(in the US) The prosecution ALWAYS bears the burden of proof to prove the defendant guilty beyond a reasonable doubt, however, if the defendant uses an alibi defense, REALISTICALLY-speaking, they are going to have to furnish some credible evidence that they WERE incapable of being present at the scene of the offense at the time of its occurrence.
