What is a "legal defense" in a criminal case?

A legal defense in a criminal case refers to a strategy employed by the defendant to challenge the prosecution's case against them. This involves presenting arguments, evidence, and legal principles to demonstrate that the defendant should not be found guilty of the charges. The defense aims to create reasonable doubt in the minds of the jurors regarding the prosecution's claims, often focusing on the validity of the evidence presented or the circumstances surrounding the alleged crime.

For example, defenses can include asserting that the defendant was not present at the crime scene, that they acted in self-defense, or that there was a lack of intent to commit the crime. Each defense strategy is tailored to the specifics of the case at hand, making it a crucial component of the criminal justice process.

The other options provided do not accurately reflect what a legal defense entails in the context of a criminal case. Legal compliance methods, civil remedies, and sets of laws defining rights pertain to different aspects of the law and do not directly relate to the strategies for defending against criminal charges.
