[1] On 25 February 2009, K & J Burns Electrical Pty Ltd (Burns) entered into a subcontract with GRD Group (NT) Pty Ltd (GRD) to undertaken electrical works on land situated at Lot 7100 Brewery Lane, Woolner, Northern Territory for a lump sum price of $354,860 (the Subcontract).
[2] Throughout the course of the Subcontract, Burns submitted 13 invoices to GRD for progress payments totalling $393,274.51, which sum included claims for extras or variations totalling $38,414.50.
[3] GRD made progress payments in relation to the first seven invoices totalling $309,959.47, leaving a balance allegedly payable under the Subcontract of $83,315.04.
[4] Under the terms of the Subcontract (clause 4), GRD was entitled to retain a portion of the monies payable under the Subcontract as security. GRD withheld $17,743.00 relying upon clause 4.
[5] Disputes arose between Burns and GRD, which resulted in claims by GRD for back charges for the cost of remedial works and for liquidated damages for late completion.
[6] On 8 February 2010, Burns served upon GRD a summary invoice (SI) No ST4289 dated 25 January 2010 entitled "PAYMENT CLAIM IN ACCORDANCE WITH CLAUSE 12.2 OF THE CONTRACT". The SI listed the 13 invoices previously rendered, the amount claimed under each invoice, the amount paid in respect of each invoice and the total amount owing. It also set out a summary of the amounts held in retention and how much of the retention monies could be retained under clause 4 of the Subcontract. The SI appears to be claiming $83,315.04 less retentions of $9,831.86, leaving a balance of $73,483.98. The SI does not include any amounts not previously the subject of an invoice.
[7] On 2 March 2010, GRD sent a reconciliation statement to Burns, which asserted that Burns was actually indebted to GRD in the sum of $19,989.07.
[8] On 23 March 2010, Burns lodged an application with the Law Society of the Northern Territory applying for an adjudication under the Construction Contracts (Security of Payment) Act (the Act) and served the application on GRD on 24 March 2010. On 31 March 2010, the Law Society of the Northern Territory appointed the defendant Brian Gallaugher (the Adjudicator), to adjudicate the dispute. After receiving submissions from the parties, the Adjudicator delivered his Determination on 23 April 2010 (the Determination). The Adjudicator determined, in favour of Burns, an adjudicated amount of $73,922.75 including GST, plus interest of $1,254.66 to the date of the Determination, plus interest accruing at the rate of $21.27 per day until payment is made.
[9] GRD has commenced this action by Motion for a declaration that the Determination is void and of no effect and for a stay of the judgment Burns has obtained following registration of the Determination pursuant to s 45 of the Act. Notwithstanding the decision of the High Court on Kirk v Industrial Relations Commission of New South Wales,[1] GRD has not sought to amend the Notice of Motion to seek an order in the nature of certiorari under O.56.01 of the Supreme Court Rules.
