Which of the following describes a "change of venue" in legal issues?

A "change of venue" refers specifically to the legal procedure of moving a trial from one location to another, primarily in order to ensure a fair trial by reducing potential bias. This action is often taken when it is believed that pre-trial publicity or local sentiment might prevent an impartial jury from being selected. For example, if a widely publicized case generates strong opinions within the original jurisdiction, a request may be made to relocate the trial to a different venue where the jurors may have less preconception about the case.

The other choices pertain to different aspects of the legal process. Changing legal representatives involves the hiring or appointment of a new attorney, which does not relate to venue. Adjusting the charges against a defendant pertains to modifications in the prosecution's case rather than the location where the trial will occur. Lastly, altering the evidence presented relates to the prosecution or defense's choice of what material to submit in court, which is separate from any implications of venue. By defining "change of venue" in this way, it becomes clear how vital it is for maintaining the integrity of the judicial process, ensuring that the outcome of trials is fair and just.
