53.This section extends the scope of section 9 of the 1991 Act to apply to SLDTs and LDTs as well as 1991 Act tenancies. That section allows either landlord or tenant to serve a notice on the other, to demand a reference to arbitration on the question of whether land required to be maintained as permanent pasture by the lease need in fact be maintained in this way. Disputes on this matter are to be within the exclusive jurisdiction of the Land Court (see paragraph 14 of the Schedule to the 2003 Act).
