What does the term “cumulative evidence” mean in Louisiana civil procedure?

Cumulative evidence in Louisiana civil procedure refers to evidence that reiterates or confirms facts that have already been established in the case. This type of evidence does not introduce new information or facts; rather, it serves to reinforce or support the existing evidence, providing additional reinforcement to beliefs already established during the court proceedings.

The role of cumulative evidence is to corroborate previous testimonies or findings rather than to provide a new foundational understanding of the case. For example, if several witnesses testify to the same event, their collective testimonies may be considered cumulative evidence that strengthens the argument rather than introducing new aspects.

This makes it clear why the other options do not accurately define cumulative evidence. Evidence that establishes new facts brings new information into a case, which does not align with the concept of being cumulative. Evidence that contradicts previous testimonies directly opposes established facts, thereby undermining rather than reinforcing them. Lastly, evidence based on hearsay is typically inadmissible and is not regarded as reliable evidence in court procedures, contrasting with the reliability sought in cumulative evidence.
