Answer:
In the United States, the sidebar is an area in a courtroom near the judge's bench where lawyers may be called to speak with the judge so that the jury cannot hear the conversation or they may speak off the record.
Explanation:
The purpose of a sidebar is to allow lawyers to discuss legal issues that may not be appropriate for the jury to hear or that might disrupt the course of the trial.
A sidebar may be necessary when an objection is designed to exclude mention of specific evidence by a witness, or when counsel doesn't want the jurors to hear argument on an objection.
