During the 25 January 1924 constituent assembly election, al-Hashimi won a seat in the assembly. Opposition to the Anglo-Iraqi Treaty became evident in the constituent assembly and protests by Iraqi lawyers were held opposing the treaty. According to Gertrude Bell, al-Hashimi, who chaired a special committee to examine and publish an opinion about the treaty, instigated the protests. According to historian Ali al-Allawi, al-Hashimi used his position on the committee "to undermine al-'Askari's cabinet and show it up as a feeble and incompetent government, unable to shepherd the country through trying times."
