Which statement about insanity testing is most accurate?

Which statement about insanity testing is most accurate?

• A. All jurisdictions use identical standards for insanity.
• B. The prosecution always bears the burden to prove insanity.
• C. Insanity is always the defense in any criminal case.
• D. The standard and burden vary by jurisdiction and may differ from other standards.

Answer: (D)

Insanity determinations are not uniform across all jurisdictions. Different places may use different tests to decide criminal responsibility at the time of the alleged crime, such as variations of the M’Naghten rule or more expansive standards like the Model Penal Code’s approach, and some jurisdictions blend or modify these tests. On top of that, the burden of proving insanity varies too—some systems place the burden on the defense to prove insanity, others place it on the prosecution to prove sanity, and some use different standards for different phases of the case. Because of this diversity, the most accurate statement is that the standard and burden vary by jurisdiction and may differ from other standards.
