The Four Major Criminal Law Defenses
Apart from the statutory defenses under criminal law, a defendant could also plead insanity. This defense is only allowed in certain cases where the defendant was voluntarily intoxicated. Insane persons cannot attain the required mental state. The four major criminal defenses are: mistake of law, impossibility, self-defense, and insanity. These are just a few examples of the defenses.
Insanity defense
The insanity defense can be used when a defendant is incapable of knowing right from wrong at the time of committing a crime. The court must be convinced that the defendant was incapable of stopping an irresistible impulse that would have caused him or her to do something wrong. An insanity defense can be effective in reducing charges of murder and other offenses to lesser levels.

The insanity defense requires that a defendant admits guilt, but argues that the act was not committed by him or her because he/she is insane. Although the insanity defense can be risky, it is an effective defense strategy that good attorneys use when the defendant’s mental state can be proven beyond reasonable doubt. A jury might doubt the innocence of the defendant.
Mistake of law defense
The mistake of defense is one of the most effective ways to defend against a crime. This defense claims that the defendant is not guilty of the crime because they misunderstood it. It is an extremely difficult defense to win because it requires the defendant to have been genuinely ignorant of the law at the time of the offense. The defense can also handle misinterpretation or omission of state laws.
This defense is available when a person has been accused of a crime that involves intention, such as robbery and theft. The mistake-of-law defense claims that the defendant made an innocuous mistake while attempting robbery on a business but didn’t intend o break the law. In this instance, the defendant might be eligible to have the case dismissed or reduced.
Self-defense defense
Whether you’re being accused of a crime or you’ve used force to defend yourself or others, a self-defense defense is a legal option for some individuals. While the legal system discourages you from using force against others the courts recognize that you have the right to defend your self when necessary. These defenses often involve the use of lethal force. But there are some key rules that should be followed to avoid a conviction.
A person convicted of a crime must first prove they were forced to do so. The most important requirement for a self-defense defense is that the action was reasonable. The court may dismiss the case if the defendant’s actions were reasonable and justified by a reasonable belief that he or she was acting in self-defense. A person may be convicted of a crime if they act in self-defense. However, the court may not find the act criminal.
Defense impossible
A legal defense against a crime can often be used to justify logical contradictions, and the impossibility defense in particular is one of the most popular. Shooting a deer when it is illegal is not considered a crime, if there was no intent to do so. The doctrine of legal inpossibility does NOT apply to attempted conspiracies. However, the concept does apply to some crimes, such as criminal negligence.
The notion of legal impossibility arises from the judicial struggle with conflicting considerations. These include the desire to protect society’s interests and the principle that legality. This factual/legal dichotomy caused countless difficulties for courts, and even simple rules were difficult to apply. This concept is most often used in the criminal context in the United States. For instance, in People v. Glass, a man was charged with attempted murder even though he was not in possession of a firearm.
