Question

cases heard by appellate courts are decided by
a judge.
a judge and jury.
a panel of judges.
a jury.

Explanation:

Appellate courts review decisions from lower courts. Unlike trial courts (where juries or a single judge may decide), appellate courts typically have a panel of judges (usually 3 or more) who hear the case and make a decision based on legal arguments and precedent, not new evidence or witness testimony. So cases in appellate courts are decided by a panel of judges.

Answer:

C. a panel of judges.
