A jury summons goes to far more people than a trial needs. The path from that list to a seated panel runs through distinct stages, each with its own standard for removal.
The pool is drawn from public lists
Courts assemble a source list from records such as voter registration and licensed drivers, aiming for a cross-section of the community.
Names are selected at random from that list and summoned, and the group that appears becomes the venire from which panels are drawn.
Because the source lists do not capture everyone equally, the composition of the pool is a recurring subject of study and litigation.
Qualification and hardship come first
Statutory qualifications apply before anything else, typically covering citizenship, age, residence in the district and command of the language used in court.
Courts then consider excuses and deferrals for hardship, which vary by jurisdiction and are decided administratively rather than by the parties.
Only after these filters does the remaining group proceed to questioning about the specific case.
Voir dire tests for bias
Prospective jurors are questioned by the judge, the attorneys, or both, about their knowledge of the case and any views that would prevent impartial service.
Written questionnaires are often used first in cases with extensive publicity, allowing sensitive answers without discussion in open court.
The purpose is not to find jurors without opinions, which is rarely possible, but to identify who can set opinions aside and decide on the evidence.
Two kinds of strike operate differently
A challenge for cause removes a juror the court finds unable to be impartial, and there is no limit on the number a party may make.
Peremptory challenges allow removal without stated reason, but each side receives a fixed number set by rule or statute.
Peremptories may not be used to exclude jurors on the basis of race or sex, and a party suspecting such use may raise an objection requiring the striking party to give a neutral explanation.
Alternates and panel size complete the process
Courts seat alternates alongside the main panel so a trial can continue if a juror becomes unable to serve, and alternates hear the entire case.
Panel size and the vote required to reach a verdict differ between criminal and civil cases and between jurisdictions.
Because procedures vary considerably by court and change over time, anyone facing service or trial relies on the instructions issued by that specific court.
