Texas Code of Criminal Procedure - CRIM P Art. 35.17. Voir dire examination

1. When the court in its discretion so directs, except as provided in Section 2, the state and defendant shall conduct the voir dire examination of prospective jurors in the presence of the entire panel.

2. In a capital felony case in which the State seeks the death penalty, the court shall propound to the entire panel of prospective jurors questions concerning the principles, as applicable to the case on trial, of reasonable doubt, burden of proof, return of indictment by grand jury, presumption of innocence, and opinion.
