• Such a challenge is either a principal challenge (if some defect renders the jury prima facie in-competent, as where the officer selecting veniremembers is related to the prosecutor or defendant) or a challenge for favor (as where the defect does not amount to grounds for a principal challenge, but there is a probability of partiality).
— Also termed challenge to the jury array. [Cases: Jury 114. C.J.S. Juries §§ 355, 359, 443–444.]
