Alternate jurors serve as backups during a trial. Their role is to remain available in case a regular juror is unable to continue participating due to illness, misconduct, or other unforeseen circumstances. These individuals attend the trial, listen to evidence, and follow court instructions, but they do not participate in deliberations unless specifically called upon. The release from service for these individuals generally occurs after the jury has been instructed, and the original twelve jurors begin deliberations. If all original jurors remain able to serve until the conclusion of deliberations, the alternates are then excused from their duties.
The use of alternate jurors ensures the continuity of a trial. This practice is crucial in preventing mistrials, which can be costly and time-consuming. Having alternates readily available safeguards against significant delays or the need to restart the entire process. The selection of alternates provides a degree of insurance against the unexpected events that can disrupt a trial. Historical context reveals that the implementation of this system has streamlined judicial proceedings and contributed to the efficiency of the legal system.
