Where a statutory review notice has been given in relation to a farm business tenancy, but—
no arbitrator has been appointed under an agreement made since the notice was given, and
no person has been appointed under such an agreement to determine the question of the rent (otherwise than as arbitrator) on a basis agreed by the parties,
either party may, at any time during the period of six months ending with the review date, apply to a professional authority for the appointment of an arbitrator by that authority.
A party may not make an application to a professional authority under subsection (1) in any case if the other party has already made an application to a professional authority under that subsection in that case.
