A court with appellate jurisdiction can review both the facts and the law, including questions of jurisdiction. It can set aside an erroneous decision and even nullify the same, if warranted. Appeal is a speedy remedy, as an adverse party can file its appeal from a final decision or order immediately after receiving it. A party, who is alleging that an appeal will not promptly relieve it of the injurious effects of the judgment, should establish facts to show how the appeal is not speedy or adequate. VCP’s empty protestations, therefore, fail to impress. There is no reason, and VCP cannot explain, why an appeal would not be speedy and adequate to address its assigned errors. VCP cannot complain of delay because it was guilty of delay itself, and it even waited until the 58th day of its receipt of the CA Decision before taking action. Clearly, petitioner resorted to certiorari as a substitute for its lost appeal. The CA did not err in dismissing the same.
