上诉 (shàng sù): to appeal (a judicial case); appeal

The defendant thought the court's sentence was too heavy and decided to appeal to a higher court.

After carefully studying the case file, the lawyer advised the client to appeal the first-instance judgment.

Because new evidence emerged, the defendant's family insisted on appealing on his behalf to seek a revised sentence.

The appeal period is only fifteen days, so he must submit the appeal petition to the court within this month.

After several months of review, the appellate court ultimately upheld the original judgment and rejected his appeal.
