Bentwich played a major role in the development of Palestinian law. According to Likhovski, he "concentrated his efforts on providing Palestine with a set of modern commercial laws that he believed would facilitate economic development and thus attract more Jewish immigration." Bentwich's perceived Zionist bias made him increasingly unpopular with Palestinian Arabs, who conducted demonstrations and other protests against his presence in the administration. Some British officials, including the Colonial Office and the Chief Justice of Palestine Michael McDonnell, saw him as a liability and agitated for his dismissal. In 1929 he was barred from representing the government at the Shaw Commission into the August riots. In late 1930 he went on leave to England, where he unsuccessfully sought to gain support for his continued role in Palestine. He was offered senior judicial positions in Mauritius and Cyprus, but turned them down. In August 1931 his appointment as Attorney-General was terminated by the Under-Secretary of State for the Colonies, who cited "the peculiar racial and political conditions of Palestine, and the difficulties with which the Administration has in consequence to bear."
