13 Importantly also, s 11(3), in relation to a dispute about the amount of the rent review provides that the question "shall be resolved" in the way set out by that subsection (emphasis supplied). In the first instance then, the appointment of the valuer, or the discussion between the two valuers, is intended to resolve the dispute. Subsection (4) of s 11 provides that a person acting under that subsection shall on request and on payment of a fee provide reasons for the "decision". Thereafter, as I have noted, the matter can be referred to the Registrar for "determination". It seems to me that the intention of s 11 is that the solution acceptable to both parties, which the Registrar is required to attempt to reach in relation to questions referred pursuant to s 16, is in relation to rent review questions to be achieved wherever possible by the appointment of a mutually agreed valuer or by discussion between valuers. It seems to me unlikely, since no doubt representations and discussions would have taken place at the stage required by s 11(3), that it was then the legislative intention that the Registrar should make further efforts to attempt to achieve a mutually acceptable solution, before proceeding to determine the matter.
