The burden of production is the responsibility of a party to provide enough evidence to support proposed facts in court cases. Usually, both parties have the burden of production. If there is not enough evidence to satisfy the burden of production, then there can be a dismissal or a directed verdict.
The burden of production is there to make sure that there is enough evidence in the suit to make it legitimate. It would be extremely difficult for juries to make decisions about cases without any evidence for the claims being made. Evidence serves to provide proof of the accuracy of proclamations of fact that a party makes. It is essential that there is enough evidence. The burden of production is a matter of law and is not optional.
