Justipedia explains Court Witness
Sometimes during a trial, the court calls its own witnesses. It does this primarily when there is an issue that needs further explanation; this is often done if the subject matter at hand is complicated. A court witness can help the jury understand what is going on. The testimonies of witnesses are often critical to the outcome of the trial. This is why the court calls its own witnesses if it believes it is necessary to clarify something. Court witnesses can also help the court in general understand the subject at hand.
