Although this book focuses primarily on the recognition and enforcement of foreign judgments in Israel, it occasionally compares Israeli law with the law of the United States, the European Union, and other countries. The examination of other countries’ law is highly germane to a review of the recognition and enforcement of foreign judgments in Israel. This is, first and foremost, because the Israeli legal system does not operate in a legal vacuum. The Israeli legislature, and the courts, draw inspiration inter alia from foreign legal systems. That is particularly true in issues concerning cross-border trade and the resolution of cross-border disputes. The principle that customary international law forms an integral part of Israeli law has been established by several rulings of the Supreme Court.
