After the widespread Arab riots of 1929 in the then British Mandate of Palestine, the Hope Simpson Enquiry was appointed to seek causes and remedies for the instability. The Commission's findings in regard to "Government responsibility towards Arab cultivators", was that the Jewish authorities "have nothing with which to reproach themselves" in the purchase of the valley, noting the high prices paid and land occupants receiving compensation not legally bound. The responsibility of the Mandate Government for "soreness felt (among both effendi and fellahin) owing to the sale of large areas by the absentee Sursock family" and the displacement of Arab tenants; noted that, "the duty of the Administration of Palestine to ensure that the rights and position of the Arabs are not prejudiced by Jewish immigration. It is doubtful whether, in the matter of the Sursock lands, this Article of the Mandate received sufficient consideration."
