Final answer:
To plead self-defense, a defendant must show imminent danger and necessary force use, with the prosecution needing to disprove such claims in a criminal case 'beyond a reasonable doubt'.
Step-by-step explanation:
To plead self-defense, a defendant must demonstrate that they believed themselves to be in imminent danger and that the use of force was necessary to avert this danger. This legal justification typically requires the defendant to show evidence that supports the reasonable nature of their fear for personal safety and the proportionality of their response. In a criminal case, unlike a civil case, the prosecution bears the burden of proving the defendant's guilt "beyond a reasonable doubt."
Hence, if a defendant effectively raises the self-defense claim, the prosecution must also disprove this defense to the same standard. Even in scenarios where the defendant is not entitled to a public defender, they have the right to legal representation. This legal right is also connected to the ability to confront and cross-examine witnesses against them – a crucial aspect when arguing self-defense.
Legal representation and the right to cross-examine witnesses are critical in self-defense cases.
