In criminal law, corroborating evidence is additional evidence that supports or confirms the testimony or evidence presented by another witness or source.
Corroborating evidence can help to strengthen the credibility of a witness or the reliability of a piece of evidence, and can be used to help establish the guilt or innocence of a defendant.
Corroborating evidence may include things like physical evidence, eyewitness testimony, or other forms of documentary or electronic evidence. It is generally considered to be more persuasive and reliable when it is independent of the primary evidence or testimony being presented.
While corroborating evidence is not always necessary to establish the guilt of a defendant, it can be useful in helping to overcome doubts or challenges to the credibility of a witness or the reliability of a piece of evidence.
