Beyond a Reasonable Doubt: Why It Matters in Criminal Law

Written by Christi Hayes and Fact Checked by The Law Dictionary Staff  

The presumption of innocence is one of the foundations of the administration of criminal law in the United States, England, and other countries that follow a common law tradition. The only way to overcome this presumption of innocence in a criminal trial is for the prosecution to prove beyond a reasonable doubt that the defendant committed the crime that he or she has been charged with. While the phrase "beyond a reasonable doubt" has entered the popular lexicon and often appears on television, in newspapers, and in films, it can sometimes be difficult for laypeople to understand what, exactly, is meant by "reasonable doubt." Here's a brief overview of what "beyond a reasonable doubt" means and why it's important. 

The Presumption of Innocence 

As mentioned, in the common law tradition anybody charged with a crime has the right to be presumed innocent until proven otherwise. This right is enshrined in the U.S. Constitution by the Fifth and Fourteenth Amendments, which protect peoples' rights to due process. The presumption of innocence is important in criminal law since being found guilty of a criminal offense could deprive a defendant of his or her liberty. Therefore, the only way the state has the ability to deprive somebody of his or her liberty is to prove beyond a reasonable doubt that that person has committed a criminal offense.

 What is reasonable doubt?

 Beyond a reasonable doubt is the highest standard of evidence that exists in the judicial systems of common law countries. As the inclusion of the word "reasonable," however, suggests, proving beyond a reasonable doubt that a person committed a crime does not mean that there is absolutely no doubt about his or her innocence. Rather, the phrase means that the established facts of the case lead the court to only one logical conclusion: that the defendant is guilty of the charges against him or her. Unreasonable doubt can still exist, but by its very nature such doubt does not lead a reasonable person to conclude that the accused did not commit the crime in question. This high standard of proof helps to reduce the likelihood of wrongful convictions.

 Does all litigation involve reasonable doubt?

 The standard of evidence is much higher in criminal cases than it is in civil litigation. As a result, civil cases require that the case be proved by the lower standards of either a preponderance of evidence or proof by clear and convincing evidence. Such standards of evidence require only a high probability that the offense was committed. Reasonable doubt can still exist in civil litigation cases because in civil cases usually only money is at stake rather than the defendant's liberty.

 Beyond a reasonable doubt is a popular phrase, but one that is not always widely understood by the general public. Yet proving beyond a reasonable doubt that somebody committed an offense is a pillar of the common law criminal justice system. This burden of proof helps reduce the risk of innocent people being deprived of their liberty and ensures that all citizens' rights are better protected.
