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 court of law, the burden of proof lies with the prosecution to demonstrate the defendant's guilt beyond a reasonable doubt.
"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
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.
There is no such amendment. The principles of justice and law in the US is that the defendant is ALWAYS innocent until PROVEN guilty. Therefore the defendant ALWAYS has the presumption of innocence on his side and the prosecution bears the burden to prove you guilty.
The only burden of proof, is that you have to convince a jury that the defendant IS. in fact, insane, and therefore, not responsible for their actions. Not as easy as it sounds, and VERY expensive considering the expert testimony that will have to be called in to testify and sway the jury's opinions.
