Final answer:
The process by which the prosecution and defense can question an expert's qualifications before they are allowed to testify in court is known as voir dire.
Step-by-step explanation:
Before a judge decides whether to consider a person an expert, the prosecution and defense both have the right to question the expert's education, training, and experience in a process called voir dire. This is an essential part of a trial, where both sides have the opportunity to examine and cross-examine witnesses. The prosecution presents witnesses first and is followed by the defense. Then each side may introduce additional witnesses to rebut the other's testimony. Throughout the trial, a judge ensures that the evidence presented is relevant and that the jury receives the proper instructions on how to deliberate the case.
