What is necessary for evidence to be deemed admissible in court according to the CCP?

For evidence to be deemed admissible in court according to the Code of Criminal Procedure (CCP), it must meet certain criteria that establish its relevance, reliability, and the absence of prejudicial impact that outweighs its probative value. Relevance ensures that the evidence directly pertains to the case, contributing to proving or disproving a material fact. Reliability assesses the credibility and trustworthiness of the evidence, making sure it is based on sound principles. Lastly, the consideration of prejudicial impact is critical because evidence that incites undue bias or emotional response can detract from a fair trial.

The other choices do not fully encapsulate the comprehensive criteria for admissibility. While obtaining evidence through lawful means is important, it is not the only determinant for admissibility. The requirement for unanimous agreement by jurors does not pertain to the admissibility of evidence but rather to jury verdicts. Similarly, while expert testimony can enhance the understanding of complex evidence, it is not a prerequisite for all types of admissible evidence. The critical focus is thus on the relevance, reliability, and the balance of prejudicial effects, making that the core reason why the selected answer is correct.
