Final answer:
Laura being excused by the plaintiff's attorney with no stated reason is an example of a peremptory challenge during jury selection, which is lawful provided it's not based on discriminatory grounds.
Step-by-step explanation:
The rejection of Laura as a juror by Michelle, the plaintiff's attorney, without providing a reason, indeed corresponds to the use of a peremptory challenge. The application of peremptory challenges is a common practice during the jury selection process of a trial.
Attorneys on both sides have a limited number of these challenges they can use to dismiss potential jurors without stating a cause, ensuring their client receives a fair trial from an impartial jury, as mandated by the Sixth Amendment.
Nevertheless, it is important to note that such challenges cannot be exercised based on discriminatory reasons such as race or sex as a result of regulations that have evolved from landmark cases like Scottsboro, which uphold the principles of the Sixth and Fourteenth Amendments.
