A report issued in March 1930 by a British Commission of Inquiry, headed by jurist Walter Shaw, investigating the 1929 Palestine riots and their origins. The commission determined that the direct responsibility for the outbreak of violence lies on the Arab side, though it was not premeditated. However, it also determined that the events have their roots in Arab animosity towards Jews related in part to the rise in Jewish immigration and purchase of lands. Therefore, it recommended that British policy on these subjects be reviewed, leading to the publication of the Hope Simpson Report and the 1930 White Paper.
