The proof that they need a doctor is the filing in Federal Court of insane petition known to most as forced liquidation bankruptcy......

The reason they must have a doctor is right here....

In criminal trials , the insanity defense is where the defendant claims they are not responsible for their actions due to mental health problems (psychiatric illness or mental handicap). Exemption of the insane from full criminal punishment dates back to at least the Code of Hammurabi . ^{[ 1 ]} There are different definitions of legal insanity, such as the M'Naghten Rules , the Durham Rule, the American Legal Institute definition, and various miscellaneous provisions (e.g., relating to lack of mens rea ). ^{[ 2 ]}

In the United Kingdom , Ireland , and the United States , use of the defense is rare; ^{[ 3 ]} however, since the Criminal Procedure (Insanity and Unfitness to Plead) Act 1991, ^{[ 4 ]} insanity pleas have steadily increased in the UK. ^{[ 5 ]} Mitigating factors, including things not eligible for the insanity defense like intoxication ^{[ 6 ]} (or, more frequently, diminished capacity ), may lead to reduced charges or reduced sentences.
