Defenses Flashcards
Insanity Tests
There are four different tests for determining whether, at the time of the crime, the defendant was so mentally ill as to be entitled to acquittal
1) M’Naghten Rule (Majority)
2) Irresistible Impulse Test (Minority)
3) Durham/New Hampshire Test
4) MPC/ALI Test
M’Naghten Rule (Insanity)
A defendant is entitled to acquittal if:
1) a disease of the mind;
2) caused a defect of reason;
3) such that the defendant lacked the ability at the time of their actions to either (a) know the wrongfulness of their actions or (b) understand the nature and quality of their actions.
Delusions, belief that one’s actions are morally right, or loss of control are not defenses unless this test is met.
Majority view
Irresistible Impulse Test (Insanity)
A defendant is entitled to acquittal only if, because of a mental illness, they were unable to control their actions or conform their conduct to the law. (minority view)
Durham/New Hampshire Test (Insanity)
A defendant is entitled to acquittal if the crime was the product of their mental illness
This is followed only in New Hampshire
MPC/ALI Test (Insanity)
A defendant is entitled to acquittal if they had a mental disease or defect, and as a result, they lacked the substantial capacity to either
1) appreciate the criminality of their conduct; or
2) conform their conduct to the requirements of the law
GA Mental Capacity Defense (Insanity)
In GA, there are two basis for an acquittal on the grounds of mental capacity
1) a person is not guilty if, at the time of the crime, the person did not have the mental capacity to distinguish between right and wrong in relation to the act, omission, or negligence resulting in the crime.
2) a person is not guilty when, at the time of the crime, the person, because of mental disease, injury, or congenital deficiency, acted as they did because of a delusional compulsion that mastered their will to resist committing the crime.
NOTE: The delusion must relate to a fact that, if true, would have justified the act.
Burden of Proof (Insanity)
All defendants are presumed sane - the defendant must raise the insanity defense
Majority – once raised the defendant must prove insanity (normally preponderance standard)
MPC – require prosecution to prove the defendant was sane beyond a reasonable doubt
Federal Court – require the defendant to prove insanity by clear and convincing evidence
GA Insanity Burden of Proof
In GA, insanity is an affirmative defense
A defendant, to overcome the presumption of insanity, must show by a preponderance of the evidence that they were insane at the time of committing the offense.
When to Raise Insanity
Although insanity may be raised at the arraignment when the plea is taken, the defendant need not raise it then. A simple not guilty at that time does not waive the right to raise the defense at some future time.
Pretrial Psychiatric Examination (Insanity)
If the defendant does not raise the insanity issue, they may refuse a court-ordered psychiatric examination to determine their competency to stand trial.
If the defendant raises the insanity issue, they may not refuse to be examined by a psychiatrist appointed to aid the court in the resolution of his insanity plea.
Post-Acquittal Commitment (Insanity)
In most jurisdictions, a defendant acquitted by reason of insanity may be committed to a mental institution until cured.
Confinement may exceed the maximum period of incarceration of the offense charged.
Diminished Capacity
Some states recognize the defense of diminished capacity under which the defendant may assert that as a result of a mental defect short of insanity, they did not have the mental state required for the crime charged.
Majority limit this defense to specific intent crimes
Insanity v. Incompetency
Insanity Defense – the issue is whether the defendant was insane at the time of the crime
Incompetency – the issue is whether, at the time of trial, the defendant cannot (1) understand the nature of the proceedings being brought against them or (2) assist their lawyer in the preparation of their defense. If either is established, trial is postponed until the defendant regains competency.
Intoxication Generally
Intoxication may be caused by any substance and may be raised whenever intoxication negates one of the elements of the crime.
The law distinguishes between voluntary and involuntary intoxication.
Voluntary Intoxication
Intoxication is voluntary if it is the result of intentional taking without duress of a substance known to be intoxicating.
Evidence of voluntary intoxication may be offered by the defendant only if the crime requires purpose (intent) or knowledge, and the intoxication prevented the defendant from formulating the purpose or knowledge
Therefore, voluntary intoxication is only a defense to specific intent crimes (not general intent, malice, or strict liability)
GA Voluntary Intoxication
In GA, voluntary intoxication is a very limited defense.
Voluntary intoxication is not a defense to any crime unless the defendant can show that the intoxication resulted in more than a temporary alteration of brain function such that the defendant could not for the requisite intent.
NOTE – voluntary intoxication is not available when the crime requires the defendant act knowingly
Involuntary Intoxication
Intoxication is involuntary only if it results from taking of intoxicating substances without knowledge of its nature, under direct duress imposed by another, or pursuant to medical advise while unaware of the substance’s intoxicating effect.
Involuntary intoxication may be treated as a mental illness, the the defendant is entitled to acquittal if they meet the jurisdiction’s insanity test.
Therefore, it can be a defense to all crimes.
GA Involuntary Intoxication
In GA, involuntary intoxication is a defense if it deprived the defendant of sufficient mental capacity to distinguish between right and wrong in relation to the criminal act.
Common Law Infancy
At common law, there could be no liability for an act committed by a child under the age of 7
For acts committed by a child between 7 and 14, there was a rebuttable presumption that the child was unable to understand the wrongfulness of there acts.
Children 14 or older were treated as adults
(Known as the rule of 7s)
Modern Infancy
most states have abolished the rule of 7s in whole or in part in favor of separate juvenile or family courts to enforce juvenile delinquency laws and to manage youthful offending in general.
GA Infancy
In GA, to be found guilty of a crime, a person must be at least 13 years old at the time of the relevant conduct
