Person has the right to appear in person in court?

Answer 1

Any time you're being prosecuted for a crime you have the right to be present in court. The only time you may not be brought to court is during motion hearings or during witness questioning.

Ultimately the judge also has the right to order you to be removed from the courtroom until such time the judge deems fit for your return.

However, you cannot be convicted without formally being present in a court of law.

Addition and clarification: While the majority of the above answer is correct, the final sentence needs clarification. A judge CAN order a defendant from the court room and confined to some location where they can witness the proceedings (e.g.: on closed circuit TV), but as long as they are represented by counsel, they are considered to be "present" (if not in body) in the courtroom.
