What is the standard of proof required for a prosecution to gain a conviction?

The standard of proof required for a prosecution to gain a conviction in criminal law is "beyond reasonable doubt." This means that the prosecution must present sufficient evidence to ensure that there is no reasonable doubt in the mind of a rational person regarding the defendant's guilt. This standard is intentionally high to safeguard the rights of individuals accused of crimes, reflecting the principle that it is better for several guilty individuals to go free than for one innocent person to be wrongly convicted.

In contrast, the "clear and convincing evidence" standard is often used in civil cases or specific areas of family law, but it does not apply at the same level of rigor required for criminal convictions. "More likely than not" refers to the preponderance of evidence standard used in civil cases, where the evidence must show that something is more than half true, which again does not meet the rigorous threshold established for criminal cases. Similarly, "preponderance of evidence" is synonymous with the civil standard, further underscoring why it is not applicable in the criminal context.
