Which phrasing may be used to describe the insanity defense, depending on jurisdiction?

• A. Not Guilty by Reason of Insanity (NGRI) only.
• B. Not Guilty by Reason of Mental Disease (NGMI) only.
• C. Not Guilty by Reason of Defect (NGMD) only.
• D. Not Guilty by Reason of Insanity (NGRI) or not guilty by reason of mental disease or defect (NGMI/NGMD) depending on jurisdiction.

Answer: (D)

Terminology for the insanity defense varies by jurisdiction. In some places it’s known as Not Guilty by Reason of Insanity (NGRI), while in others it uses Not Guilty by Reason of Mental Disease or Defect (NGMI/NGMD). Some jurisdictions use one form or the other, or refer to both depending on the context. So the phrasing that covers this variation—Not Guilty by Reason of Insanity or not guilty by reason of mental disease or defect, depending on jurisdiction—best captures how this defense is described in practice. The other options assume a single label for all jurisdictions, which isn’t accurate.
