ACT: Respondent to Comply with Determination


The Act requires payment of any adjudicated amount within 5 business days of the date of receipt of the determination or by the decided date of payment, whichever is the later. Adjudicate Today will always forward a copy of the decision to both parties. The date of receipt of the decision by the respondent is day 0 for the purpose of counting 5 business days.

Where the respondent is to make a payment to the claimant, the claimant should forward the respondent:

  • a copy of the adjudication decision (this helps avoid a dispute over date of receipt of the decision); and
  • an invoice totaling the adjudicated amount, all fees and charges of the adjudicator and any interest awarded by the adjudicator (calculated to the date of the invoice).

It is not uncommon for a respondent to make a "part-payment" during the course of the adjudication proceedings. However, it is the adjudicator's obligation to decide the matter on the basis of the adjudication application and not some lesser (or greater) amount. In this case, the claimant should reduce the amount invoiced to the respondent by the amount of the "part-payment".

If the adjudicator decides the claimant has no entitlement to an adjudicated amount, the decision may still require the respondent pay some component of the costs of the adjudication. Recovery of such costs is available to the claimant under the Act.

As the debt created by the adjudication decision is a statutory debt, it is generally easy to enforce in the courts. Concurrent proceedings whether they be mediation, arbitration, expert determination or litigation can't prevent the adjudication proceeding or the effect of the adjudication decision.

Right of Appeal

An appeal may be made to the Supreme Court on any question of law arising out of the adjudication decision; provided either:

  • both parties agree; or
  • the Supreme Court grants leave.

The Supreme Court will only grant leave when the determination of the legal question could substantially affect the rights of one or more parties and there is either a manifest error of law on the face of the decision or there is strong evidence of an error in law and determination of the question may add to the certainty of the law.

Generally such applications are expensive to run and difficult to win. However some grounds on which a court may intervene include:

  • there was no construction contract (within the meaning of the Act) between the parties;
  • the respondent was not served with a payment claim under the Act;
  • the claimant is guilty of fraud;
  • within the requirements of the Act, the adjudicator failed to treat any party fairly (natural justice).

Generally adjudicator error, unless it goes to jurisdiction, is insufficient to attract court intervention. In most cases it is quicker and more cost effective to comply with the adjudication decision and sue separately for repayment of any alleged overpayment. In all such matters, legal advice should be taken from a lawyer who is familiar with the building and construction industry and the Act.

A respondent who is dissatisfied with the adjudicator's decision and has paid the amount due to the claimant has the option of suing separately (or exercising any other dispute resolution rights as described in the contract) for repayment of any alleged overpayment. However it is the respondent (not the claimant) who is now "out of pocket" and must prove a cause of action with all the prospects of the delay, cost and stress involved in recovering the alleged overpayment.

Similarly, if the claimant considers that the amount decided by the adjudicator is too little, the claimant can sue (or exercise any other dispute resolution rights as described in the contract) for the balance, but that claim cannot be a claim under the Act.

Please move to the next step on the flowchart being EITHER "Full adjudicated amount, including interest & adjudication fees paid. Payment Process under the Act complete" OR "Respondent does NOT pay full or any part of adjudicated amount, including any adjudication fees & interest", whichever is applicable.
