Cal. Const. art. I, § 15

The defendant in a criminal cause has the right to a speedy public trial, to compel attendance of witnesses in the defendant’s behalf, to have the assistance of counsel for the defendant’s defense, to be personally present with counsel, and to be confronted with the witnesses against the defendant. The Legislature may provide for the deposition of a witness in the presence of the defendant and the defendant’s counsel.

Persons may not twice be put in jeopardy for the same offense, be compelled in a criminal cause to be a witness against themselves, or be deprived of life, liberty, or property without due process of law.
