Using Evidence in Court

Every case requires evidence to prove facts and dispute assertions made by the opposing counsel. The aforementioned four types of evidence (real evidence, demonstrative evidence, documentary evidence, and testimonial evidence) generally fall under two larger categories: direct or circumstantial.

Direct Evidence

Direct evidence is any evidence that “speaks for itself” such as a confession, a weapon, or an eyewitness account (American Bar Association). Direct Evidence “is evidence that directly links a defendant to the crime for which they’re on trial without any need for inference” ( Rasmussen University ).

Circumstantial Evidence

Circumstantial evidence is any evidence that implies or infers information such as the crime scene appearance, physical evidence that suggests criminal activity, or testimony that suggests links with other crimes ( The American Bar Association ).

Admissibility of Evidence

Both direct and circumstantial evidence play a large role in criminal cases. However, not all evidence carries the same amount of influence in a courtroom. This depends greatly on the type of evidence, whether or not it is circumstantial or direct, and its relevance to the case.

Real Evidence

One of the most common and effective uses of evidence is real evidence. Real evidence classifies material evidence that is relevant to the case. Real evidence is also known as physical evidence.

Demonstrative Evidence

In contrast, Demonstrative evidence is additional evidence used to explain or demonstrate the relevance of other evidence such as testimonial evidence.

Documentary Evidence

Documentary evidence is the presentation of documents at trial. Similar in concept to real or physical evidence, documentary evidence is direct evidence that moves to prove or disprove facts presented at trial.
