I think this comes under section 87 and/or 90 (both below)
87 Orders varying contributions or payment methods
(1) The Tribunal may, on application, make either or both of the following orders if the Tribunal considers that any amount levied or proposed to be levied by way of contributions is inadequate or excessive or that the manner of payment of contributions is unreasonable:
(a) an order for payment of contributions of a different amount,
(b) an order for payment of contributions in a different manner.
90 Contributions for legal costs awarded in proceedings between owners and owners corporation
(1) This section applies to proceedings brought by one or more owners of lots against an owners corporation or by an owners corporation against one or more owners of lots (including one or more owners joined in third party proceedings).
(2) The court may order in the proceedings that any money (including costs) payable by an owners corporation under an order made in the proceedings must be paid from contributions levied only in relation to the lots and in the proportions that are specified in the order.
(3) The owners corporation must, for the purpose of paying the money ordered to be paid by it, levy contributions in accordance with the terms of the order and must pay the money out of the contributions paid in accordance with that levy.
(4) This Division (other than provisions relating to the amount of contributions) applies to and in respect of contributions levied under this section in the same way as it applies to other contributions levied under this Division.
