What must defendants do if they choose to testify?

When defendants choose to testify in their own defense, they have a legal obligation to do so truthfully. This requirement is rooted in the integrity of the judicial process; providing false testimony can lead to serious consequences, including charges of perjury. Truthfulness under oath is essential, as it ensures that the information presented is accurate and credible, allowing the judicial system to reach a fair and just outcome based on reliable evidence.

While a defendant is certainly free to choose whether to testify at all, if they do decide to take the stand, honesty is paramount. The emphasis on truthful testimony reflects the principle that the pursuit of justice requires a commitment to reality and factual honesty.

In this context, the other choices do not hold true in the same legal sense. The option regarding testifying in a manner favorable to themselves does not capture the essence of the obligation to provide truthful testimony. Additionally, while defendants can opt not to testify, this choice does not directly relate to the requirements or obligations if they do take the stand. Finally, there is no legal requirement for defendants to provide additional evidence simply by choosing to testify.
