When a criminal case is appealed, a panel of judges can reverse the case if:

A. a witness has decided to change his testimony.
B. there was a legal problem during the first trial.
C. the defendant has hired a new attorney.
D. the police have found convincing new evidence.

B. there was a legal problem during the first trial.

When a criminal case is appealed, a panel of judges can reverse the case if:

B. there was a legal problem during the first trial.

The appeals court reviews the record of the original trial to determine if any legal errors occurred during the proceedings. If the panel of judges finds that there was a legal problem — such as improper jury instructions, admission of evidence that should have been excluded, or misconduct by the prosecutor or judge — it may reverse the case and order a new trial or other remedy. Changes in witness testimony, hiring a new attorney, or new evidence are factors that may affect the outcome of an appeal, but they are not the primary reason for a reversal.
