What must be ensured about evidence before giving testimony in court?

Before giving testimony in court, it is essential that evidence must be accessible during the testimony. This accessibility allows the witness to refer to the evidence, ensuring clarity and accuracy in their statements. Being able to reference the evidence helps the court understand the context and significance of the testimony provided. The accessibility of evidence also aids in establishing credibility and strengthens the integrity of the testimony, as the witness can support their claims with physical or documentary evidence that the court can evaluate in real-time.
