, but are an important part of the system for achieving a just result.

Prevailing in court requires a good understanding of the rules of evidence in the given venue. The rules vary depending upon whether the venue is a criminal court, civil court or family court, and they vary by jurisdiction. One reason to have a lawyer, among others, is that he or she should be familiar with the rules of evidence.

However, the rules of evidence may prohibit one from presenting one's story just as one likes.

These include the military tribunals established by the United States of America and tribunals used in Australia to try health professionals.

Some important rules involve relevance
Relevance (law)
Relevance, in the common law of evidence, is the tendency of a given item of evidence to prove or disprove one of the legal elements of the case, or to have probative value to make one of the elements of the case likelier or not. Probative is a term used in law to signify "tending to prove."...
