Key Takeaways
- The Building and Construction Industry Security of Payment Act 1999 (NSW) and the Contractors Debts Act 1997 (NSW) are intended to be construed harmoniously as distinct legislative instruments governing a similar arena.
- A head contractor will not be able to enforce an adjudication determination against a principal for an amount which includes a sum that the principal is required to pay a subcontractor upon the subcontractor having duly obtained and served a debt certificate on the principal.
Overview
The decision of the New South Wales Supreme Court in Warrane Design Construct Fit-Out Pty Ltd v Woonona Bulli RSL Memorial Club Ltd [2025] NSWSC 123, delivered on 27 February 2025, highlights a key interaction between the Building and Construction Security of Payment Act 1999 (NSW) (SOP Act) and the Contractor Debts Act 1997 (NSW) (Debts Act). The Court ultimately took the view that these legislative instruments should be construed in a way which promotes their harmonious co-existence, where possible.
Background Facts and Context
On 7 December 2023, Woonona-Bulli RSL Memorial Club Ltd (Principal) entered into a contract with Warrane Design Construct Fit-Out Pty Ltd (Head Contractor) for carpark upgrade works (Contract), consisting of the addition of new carparking spaces and upgrades to existing facilities (the Works). On 11 December 2023, the Head Contractor entered into a subcontract with All Civil Solutions Group Pty Ltd (Subcontractor) for the carrying out of the majority of the Works.
Debt Certificates
On three occasions (being 16 August 2024, 13 December 2024 and 13 February 2025), the Subcontractor served on the Principal debt certificates per the process codified in section 6 of the Debts Act, which had been duly issued by the New South Wales District Court as required by section 7. The service of the debt certificates on the Principal meant that the Subcontractor was assigned the benefit of payment from the Principal (instead of the Head Contractor) up to the amount designated in the debt certificates. The culmination of the three debt certificates equated to $2,556,231.20 as being due from the Principal to the Subcontractor (Debt Certificate Sum). In effect, this amount would be deducted from the Contract sum payable to the Head Contractor. The Principal attended to payment of part of the Debt Certificate Sum, leaving a balance of $1,200,670.24 outstanding to the Subcontractor, as at the date of the proceedings.
The Adjudication
Simultaneouisly, the Head Contractor sought and obtained an adjudication determination against the Principal on 25 January 2025 for the sum of $2,094,018.44 in respect of the Works, pursuant to section 22 of the SOP Act (Determination). Throughout the adjudication, it was never raised that the debt certificates issued by the Subcontractor would impact the amount of the Determination. Subsequently, on 3 February 2025, an adjudication certificate was filed in the New South Wales Supreme Court, and judgment was obtained in favour of the Head Contractor for the amount of $2,141,780.73 (Supreme Court Judgment).
Garnishee Order
Following the Supreme Court Judgment, on 13 February 2025, the Head Contractor also applied for a garnishee order, directed to the Commonwealth Bank of Australia. The New South Wales Supreme Court, on 20 February 2025:
- issued the requested garnishee order; and
- ordered that any credit balance in the Principal’s bank account was attached until the Supreme Court Judgment amount was paid.
Principal’s Response
In connection with the prior events, the Principal filed, in separate proceedings (SOPA Proceedings) on 20 February 2025, a Technology and Construction List Summons and List Statement, seeking to have the Determination quashed to the extent of $1,030,281.79. The Principal also later sought an order to stay the Supreme Court Judgment and for the associated attachment and garnishee order to be aside.
Decision
Justice Stevenson held that the Supreme Court Judgment obtained must be stayed to the extent that the Principal was indebted to the Subcontractor for the outstanding portion of the Debt Certificate Sum, and that the attachment and garnishee order be set aside.
Reasoning
His Honour outlined that as the Subcontractor had served the debt certificates on the Principal (which effected an assignment), the Supreme Court Judgment overstated the amount which was actually due to the Head Contractor under the Contract, by $1,200,670,24. Therefore, the Supreme Court Judgment was to be stayed to this extent. Justice Stevenson remarked that to find any other conclusion would ignore the operation of the Debts Act, and that in any circumstance, the SOP Act and Debts Act should be interpreted in a way which achieves legislative harmony. In acknowledgement of the fact that the intended harmony is not quite realised from a technical point of view, the Court stayed the Supreme Court Judgment ‘as a matter of discretion’ (at [18]).
The Court ultimately found that the remaining balance of $941,110.49 from the Supreme Court Judgment was owed by the Principal to the Head Contractor. The Court ordered that this sum was to be paid into court for the purposes of the SOPA Proceedings.
Implications
Whilst this is an intermediary decision, it outlines a key tension point which may arise throughout the duration of a construction project in NSW, where a head contractor seeks adjudication to enforce payment by a principal contemporaneously with a subcontractor issuing debt certificates to the principal. The decision reinforces the importance of legislation in the nature of the Debts Act, to ensure subcontractors are paid for their work. It also emphasises that a head contractor cannot utilise the SOP Act to recover a debt in so far as the right to be paid such debt has been duly assigned to a subcontractor per the statutory mechanisms in the Debts Act.
