What does "Case in Chief" refer to?

"Case in Chief" refers to the primary evidence presentation by a party during a trial. This is the stage in a court proceeding where a party introduces its main evidence to support its claims or defenses. It provides an opportunity for the party to present witnesses, documents, and other relevant materials that form the backbone of its argument. The case in chief is essential, as it establishes the facts and legal contentions that the party seeks to prove to the judge or jury.

While other options mention important legal concepts and documents, they do not accurately capture the essence of what "Case in Chief" signifies in a courtroom context. Legal briefs and obligations of proof relate to the overall legal framework and procedures, but they do not specifically address the direct presentation of evidence, which is the crux of a case in chief.
