Defendant's Choice not to Testify or Present Evidence is the right of the defendant in a criminal trial to remain silent. This is known as the Fifth Amendment right to remain silent and is a fundamental part of the right to due process of law. This right is extended to all criminal defendants in the United States, regardless of the nature of the crime they are charged with. There are two types of Defendant's Choice not to Testify or Present Evidence: voluntary and involuntary. Voluntary Defendant's Choice not to Testify or Present Evidence occurs when the defendant chooses not to testify or present any evidence in their defense. This choice is made freely by the defendant, without any external influence or coercion. It is important to note that the defendant is not required to testify or present evidence in their defense, and that the jury is not permitted to draw any negative inferences from the defendant's silence. Involuntary Defendant's Choice not to Testify or Present Evidence occurs when the defendant is physically or mentally unable to testify or present any evidence in their defense. This could be due to physical or mental incapacitation, or due to the defendant being under the age of 18. In such cases, the court may appoint a guardian or representative to make decisions on the defendant's behalf. The jury is still not permitted to draw any negative inferences from the defendant's inability to testify or present evidence.
