After the nomination of the new High Commissioner Sir John Chancellor to succeed Lord Plumer in December 1928, the question was re-examined, and in February 1929 legal opinion established that the mandatory authority was within its powers to intervene to ensure Jewish rights of access and prayer. Al-Husseini pressed him for a specific clarification of the legal "status quo" regarding the Wall. Chancellor mulled weakening the SMC and undermining al-Husseini's authority by making the office of mufti elective. The Nabi Musa festival of April that year passed without incident, despite al-Husseini's warnings of possible incidents. Chancellor thought his power was waning, and after conferring with London, admitted to al-Husseini on 6 May that he was impotent to act decisively in the matter. Al-Husseini replied that, unless the Mandatory authorities acted, then, very much like Christian monks protecting their sacred sites in Jerusalem, the sheikhs would have to take infringements of the status quo into their own hands, and personally remove any objects introduced by Jews to the area. Chancellor asked him to be patient, and al-Husseini offered to stop works on the Mount on condition that this gesture not be taken as a recognition of Jewish rights. A change of government in Britain in June led to a new proposal: only Muslim works in the sector near where Jews prayed should be subject to mandatory authorisation: Jews could employ ritual objects, but the introduction of seats and screens would be subject to Muslim authorisation. Chancellor authorised the Muslims to recommence their reconstructive work, while, responding to further Zionist complaints, prevailed on the SMC to stop the raucous Zikr ceremonies in the vicinity of the wall.
