Which code prescribes the rules of evidence in all contradictory civil and criminal proceedings in Louisiana?

The Code of Evidence is the correct choice because it specifically governs the rules of evidence applicable in both civil and criminal proceedings in Louisiana. This code outlines how evidence is to be collected, presented, and assessed in court, ensuring that legal proceedings are conducted fairly and consistently.

In Louisiana, the Code of Evidence integrates rules that are essential for the admissibility of evidence, addressing issues such as relevance, hearsay, and witness qualifications. This is crucial for maintaining the integrity of the judicial process and protecting the rights of all parties involved in litigation.

The other options refer to different aspects of the law. The Civil Code primarily deals with private relationships between individuals and does not focus on evidentiary standards. The Civil Code of Procedure involves the rules governing civil legal proceedings and processes, not specifically rules of evidence. Meanwhile, the Criminal Code of Procedure relates to criminal legal processes and proceedings but does not encompass the broader rules of evidence applicable to both civil and criminal cases.
