In 1922, a Status Quo agreement issued by the mandatory authority forbade the placing of benches or chairs near the Wall. The last occurrence of such a ban was in 1915, but the Ottoman decree was soon retracted after intervention of the Chacham Bashi. In 1928 the District Commissioner of Jerusalem, Edward Keith-Roach, acceded to an Arab request to implement the ban. This led to a British officer being stationed at the Wall making sure that Jews were prevented from sitting. Nor were Jews permitted to separate the sexes with a screen. In practice, a flexible modus vivendi had emerged and such screens had been put up from time to time when large numbers of people gathered to pray.
