Final answer:
The statement is true as appellate courts, including the United States Supreme Court, primarily review cases from lower courts to ensure there were no procedural or legal errors that affected the outcome, with a significant focus on constitutional issues and differing interpretations of law.
Step-by-step explanation:
The statement that the main task for an appellate court is to review cases for judicial error is true. Appellate courts have appellate jurisdiction, meaning they have the power to hear a case after a lower court has made a decision. These courts review the procedures and the application of law in the original court's proceedings to ensure that no errors were made that could affect the outcome of the case. In the context of the United States judicial system, the appellate jurisdiction of the Supreme Court allows it to review cases from lower courts, primarily to address constitutional questions or differing interpretations of law. Judicial review, while often associated with reviewing the constitutionality of statutes may also encompass evaluating judicial decisions from lower courts.
