396.Apart from certain categories of unopposed application (section 97), the Tribunal must consider applications for variation, discharge, preservation or renewal on their merits. Section 98(a) imposes a test of reasonableness. The Tribunal must consider the factors set out in section 100. These factors are also relevant to paragraph (b) which provides for a different test for applications under sections 34(3) or 37(1) to preserve a right to enforce a burden in the face of a proposal to register a deed of variation or discharge. In these cases the deed has already been signed either by a majority in the community or by all of the adjacent proprietors. Where an application is made under section 37(1) the deed must have been signed by the owners of adjacent units (if any) and by the owner of the affected unit for the paragraph (b) test to apply. If there are no adjacent units the deed under section 35 may be signed by the owner of the affected unit alone. In this case the test in paragraph (a) applies. As there are no other signatories there are no special circumstances to distinguish this case from that of an ordinary application under section 90(1)(a).
