Presumption of Innocence: The presumption of innocence is a legal principle that states that a person accused of a crime must be considered innocent until proven guilty. This means that the burden of proof lies with the prosecution to prove that the defendant is guilty beyond a reasonable doubt. This principle is enshrined in the United States Constitution in the Fifth Amendment and is based on the principle of fairness. Burden of Proof: The burden of proof is the obligation of a party in a legal case to prove their claims. This burden is usually placed on the prosecution to prove that the defendant is guilty beyond a reasonable doubt. In civil cases, the burden of proof is usually a preponderance of the evidence, meaning that the party must prove that it is more likely than not that their claims are true. Reasonable Doubt: Reasonable doubt is a legal standard of proof that is required for a conviction in criminal cases. It is a higher standard than a preponderance of the evidence, which is used in civil cases. Reasonable doubt is based on the principle that the defendant is innocent until proven guilty and requires the prosecution to prove the defendant’s guilt beyond a reasonable doubt. This means that the prosecution must convince the jury that there is no reasonable doubt as to the defendant’s guilt.
