Common questions
Frequently Asked
3
What must the prosecution prove for a defendant to be found not guilty under the Model Penal Code?+
The prosecution must prove that the defendant's liability rests on conduct that includes a voluntary act or a physically capable omission. Without that showing the defendant is not guilty of the offense.
Supporting sources
How does a not guilty plea by reason of insanity differ from a standard not guilty plea?+
A standard not guilty plea asserts that the prosecution failed to prove the elements of the crime. A not guilty plea by reason of insanity concedes the act but claims mental illness prevented criminal responsibility, typically leading to commitment rather than release.
Supporting sources
Does a not guilty verdict mean the defendant is factually innocent?+
No. A not guilty verdict means only that the prosecution did not meet its burden of proving guilt beyond a reasonable doubt. It does not affirmatively establish factual innocence.
