What is the test for a self-defense instruction?

To support a self-defense instruction, there must be substantial evidence that the defendant (1) reasonably believed that he was in imminent danger of suffering bodily injury or was in imminent danger of being touched unlawfully; (2) reasonably believed that the immediate use of force was necessary to defend against that danger; and (3) used no more force than was reasonably necessary to defend against that danger. (CALCRIM No. 3470; People v. Romero (1999) 69 Cal.App.4th 846, 853.)
