Final answer:
The Supreme Court serves as the higher court with appellate jurisdiction in Israel, overseeing lower court decisions.
Step-by-step explanation:
The higher court that serves as the appellate court in Israel is the Supreme Court. This court reviews decisions made by lower courts and has appellate jurisdiction to do so. Similar to the U.S. judicial system, the district courts have original jurisdiction, while appellate jurisdiction allows higher courts to review cases from the lower courts. In Israel's judicial system, the Magistrate Courts and District Courts act as the trial or first instance courts, depending on the matter at hand, while the Supreme Court is at the top of the hierarchy, handling appeals and overseeing legal precedents.
