What type of objection prevents a witness from answering and could lead to a mistrial?

In legal proceedings, when an objection is "sustained," it means that the judge agrees with the objection and prohibits the witness from answering the question posed by the attorney. This type of ruling underscores the importance of courtroom decorum and procedural correctness.

If a witness is prevented from answering due to a sustained objection, it can significantly affect the flow of the trial and potentially impact the jury's perception of the evidence being presented. In some cases, if a sustained objection is considered to have significantly compromised the fairness of the trial, it could lead to a mistrial.

This concept is rooted in ensuring that all evidence presented is relevant and admissible according to legal standards. Thus, understanding the implications of a sustained objection is crucial in a courtroom setting.
