Paper For Above instruction

The legal landscape of criminal defense is complex, with a variety of defenses that can be employed by defendants to challenge criminal charges. Among these, common law defenses have historically played a significant role in shaping criminal jurisprudence. This paper explores the principal types of common law defenses used in criminal cases, analyzes their similarities and differences, and provides illustrative court case examples to demonstrate their application.

Overview of Common Law Defenses in Criminal Cases

Common law defenses are defenses rooted in traditional legal principles that have been developed over centuries through judicial decisions. They serve as legitimate reasons or justifications that can absolve or reduce liability for criminal conduct. The primary common law defenses include insanity, self-defense, duress, necessity, and mistake of fact.

Insanity

The insanity defense contends that a defendant should not be held criminally responsible because, at the time of the offense, they lacked the mental capacity to understand the nature or wrongfulness of their actions. The M'Naghten Rule, established in 1843, remains influential in many jurisdictions, asserting that a defendant is insane if, due to mental illness, they did not know what they were doing or did not understand that it was wrong.

Example: In the case of Commonwealth v. Pike (1855), the defendant was found not guilty by reason of insanity after attempting to murder his wife, based on the argument that he was unable to comprehend his actions due to mental illness.

Self-Defense

Self-defense allows a defendant to justify their actions by demonstrating they used reasonable force to protect themselves from imminent harm. The rationale is that individuals have the right to defend their own safety against unlawful threats, provided their response was proportionate.

Example: The case of State v. Kekoa (2010) involved a defendant who was acquitted of assault after demonstrating that her use of force was necessary to fend off an attack from an assailant, emphasizing the reasonable belief of imminent danger.

Duress

The duress defense is based on the premise that a person should not be held criminally responsible if they committed a crime under the threat of imminent harm or death. This defense recognizes the compelling nature of external pressures that override free will.

Example: R v. Pommell (1995) involved a defendant who was convicted of possessing a firearm but argued duress because he feared for his life if he refused the orders of an armed accomplice. The court considered whether the threat was immediate and whether the defendant had a reasonable apprehension.

Necessity

Necessity as a defense asserts that a defendant's unlawful act was justified due to the need to prevent a greater harm. This defense is applied when there are no adequate legal alternatives and the harm avoided outweighs the crime committed.

Example: In United States v. Bailey (1980), the defendants argued that their illegal acts were made necessary by threatening circumstances, such as a life-threatening situation that justified their conduct.

Mistake of Fact

This defense involves a mistaken belief about facts that, if true, would negate an element of the crime, such as intent. Mistake of fact generally does not apply to strict liability crimes but can be a valid defense in specific circumstances.

Example: In the case of United States v. Dean (1989), the defendant claimed he was unaware that the package he received contained illegal substances, and the court accepted this mistake as a defense.

Comparison and Analysis

These common law defenses vary in their scope, application, and the standards of proof required. Insanity defenses focus on mental capacity, whereas self-defense, duress, and necessity involve external circumstances justifying otherwise unlawful actions. Mistake of fact pertains to misunderstandings about factual circumstances.

Similarities:

- All defenses serve as justifications or reasons exempting criminal liability.

- They require the defendant to establish the defense by a preponderance of evidence or clear proof.

- They often depend on the circumstances surrounding the offense and the defendant's state of mind or external pressures.

Differences:

- Insanity primarily addresses mental incapacity, while others involve external threats or mistaken beliefs.

- The standards of proof and evidentiary requirements differ; insanity often demands psychiatric evaluation, whereas self-defense and duress require demonstration of the threat's immediacy and reasonableness.

- The scope of applicability varies: insanity is generally a mental health issue, whereas the others relate more to external factors influencing behavior.

Conclusion

Common law defenses are integral to the criminal justice system, providing fairness by acknowledging circumstances that mitigate or exclude criminal liability. Recognizing their distinctions and applications enables legal practitioners to craft effective defenses and promote justice. Continued judicial interpretation and statutory modifications have refined these defenses, but their core principles remain foundational.
