CHALLENGE FOR CAUSE a challenge based upon a particular reason (such as bias) specified by law or procedure as a reason that a party (or his lawyer) may use to disqualify a prospective juror.
CHALLEGE TO JURY ARRAY a formal objection to the entire panel of grand or petit jurors. The basis of such a challenge is that something has been done or omitted to the prejudice of the substantial rights of the challenging party.
GENERAL CHALLENGE a type of challenge for cause based on grounds from which, if shown to exist, the disqualification of the juror follows as a legal conclusion. Known as a CHALLENGE FOR PRINCIPAL CAUSE at common law.
PEREMPTORY CHALLENGE a right given to attorneys at trial to dismiss a prospective juror for no particular reason; the number of times an attorney can invoke this right is usually limited. If a specific reason exists why a particular juror may not fairly decide a matter, the juror may be CHALLENGED FOR CAUSE. This conserves the peremptory challenges. Even the government can use these challenges.
