Understanding the Right and Wrong Test: Legal Insights on Insanity Defense

Definition & Meaning

The right and wrong test, often referred to as the McNaghten rules, is a legal standard used to determine criminal insanity. According to this doctrine, a person may not be held criminally responsible for their actions if a mental disability prevents them from understanding the nature of their act or knowing whether it was right or wrong. In essence, if a defendant cannot distinguish between right and wrong at the time of the crime, they may be deemed legally insane. This rule originated in England during the mid-1800s and has been adopted by various courts in the United States in different forms.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A person with a severe mental disorder commits a robbery but genuinely believes they are acting in self-defense due to hallucinations. Under the right and wrong test, they may be found not guilty by reason of insanity.

Example 2: A defendant diagnosed with schizophrenia commits a violent act but, due to their condition, does not understand that their actions are wrong (hypothetical example).
