In jury selection, the method used by either the prosecution or defense attorneys to strike or to remove prospective jurors from the available jury pool because of prejudices they might have, either toward the defendant or the prosecution.

Prospective jurors may also be excused from jury duty because of being law enforcement officers, relatives of law enforcement officers, court officers, or relatives of court officers.

Any obvious bias for or against a defendant may result in the exclusion of the biased prospective juror.
