In Louisiana's court system, witnesses testify and evidence is presented at the trial court or district court level. This is where the facts of a case are established through witness testimonies, the presentation of evidence, and the examination of arguments from both parties involved in a dispute.

Trial courts are the foundational layer of the judicial system where trials occur, and judges or juries listen to the case. The trial court's role is to ascertain the truth of the matter at hand, making determinations based on the presented evidence. Once a verdict is reached, if one of the parties believes there has been a misapplication of law or procedure, they can appeal to a higher court, but the appeal process does not involve new testimony or evidence; it focuses instead on the application of law during the trial.

The appellate court, circuit court, and supreme court all operate at different levels of the legal hierarchy and generally do not engage in the presentation of new evidence or witness testimony. Instead, they review the proceedings of lower courts to ensure that legal standards were upheld throughout the trial process. Therefore, the trial court or district court is the appropriate answer when discussing where testimonial and evidential proceedings occur.
