[2023] VCAT 923
plaintiff. Order that BTH Construction Group Pty Ltd pay the applicants $17,750; applicants' claim against Mr Kassab dismissed; BTH's counterclaim dismissed; applicants granted leave to apply for interest and...
VCAT found that the house owners contracted with BTH Construction Group Pty Ltd for roof plumbing and cladding works, not with Mr Kassab personally. The company either caused or permitted unlicensed persons to carry out regulated plumbing work. The Tribunal treated the owners as having elected restitution (they did not press their damages case) and held there was a 'major failure' under the Victorian application of the Australian Consumer Law because they would not have engaged the services had they known they were unlicensed and the work could not be properly certified. The Tribunal ordered BTH to repay $17,750 (payments for roof work, guttering, and materials); the claim against the individual was dismissed and the company's counterclaim was dismissed.

The Powarchuks engaged roof and associated works for an owner-builder project at Maribyrnong. A quotation (referred to as #48849) was provided in December 2019, work proceeded in stages (upper roof/deck, box guttering and flashing, and later cladding), and payments were made: $6,000 for the initial roof works (paid into BTH's bank account), $3,000 in cash for box guttering and flashing, and $8,750 as a 50% payment towards cladding (the contract price ultimately adjusted to $17,500). The owners also hired an elevated working platform (EWP) and paid $4,025.56 for hire (Reasons, Formation of the contract para 5; 'The upper roof' and 'The cladding' sections).
Disputes arose: the owners later discovered that the person who performed plumbing works, Mr Kassab, was not a licensed plumber, that some installed cladding was not the specified Colorbond .55 but included a .42 product (Monolith), and that there were defects. The owners wrote a complaint letter dated 2 March 2020 seeking a refund and a compliance certificate and indicating they intended to have the work redone (see 'The complaint letter'). BTH and/or Mr Kassab asserted they had provided or arranged licensed plumbers, and BTH counterclaimed for unpaid contract balance and other losses. Procedurally, the matter proceeded to VCAT; the hearing occurred on 27–28 October 2022 before Member C Edquist and the Tribunal issued orders on 9 August 2023.
VCAT found the contract was with BTH (not with Mr Kassab personally), held that BTH had caused or permitted unlicensed persons to carry out plumbing work contrary to s 221H(3) of the Building Act, found a 'major failure' under the Australian Consumer Law (Victoria), and awarded restitutionary damages of $17,750 against BTH. Claims against Mr Kassab were dismissed and BTH's counterclaim was dismissed (Order; Formation of contract, para 5; 'Did the contractor charge...' and ACL analysis).
Three interlocking legal foundations drove the outcome.
Contracting party: Documentary and payment evidence (quotation, invoices, payment of $6,000 into a BTH bank account, and the invoices tendered) weighed heavily. Member Edquist found the weight of those materials showed BTH had entered into the contract and the contract was not with Mr Kassab personally (Formation of the contract, para 5). Because the contract was with BTH, the action against Mr Kassab personally failed.
Licensing/compliance and statutory limitation on entitlement to payment: The Tribunal analysed Part 12A of the Building Act and s 221HA, which limits entitlement to consideration where a person enters a contract to carry out plumbing work and causes or permits unlicensed persons to do that work. The respondents did not produce evidence of licensed plumbers at the hearing; concessions and the failure to call alleged plumbers meant the Tribunal accepted that unlicensed persons carried out the plumbing work. The Tribunal therefore held BTH was a person who had entered into the contract to carry out plumbing work and had caused or permitted unlicensed persons to carry out that work (see 'Discussion' under s 221HA). That statutory framework narrows what BTH could claim as consideration and provides a mechanism for recovery of amounts paid in contravention of the Part 12A regime.
ACL (Victoria) remedies and 'major failure': The Tribunal accepted the owners' reliance on the Victorian application of the Australian Consumer Law. The Tribunal found the supply breached the statutory guarantee of due care and skill and that the failure was 'major' within s 268 because the owners would not have acquired the services had they known of the lack of licensing and because the services were substantially unfit and could not be remedied easily within a reasonable time (ACL analysis around paras [116]-[135]). That permitted lawful termination under s 267(3)(a) and restitutionary relief (s 267(4)). The Tribunal therefore awarded restitutionary damages for payments that were wasted or rendered useless: $6,000 (roof), $3,000 (guttering/flashings), and $8,750 (materials/cladding), totalling $17,750.
Additionally, the Tribunal required the applicants to elect between damages for defects and restitution. The applicants had pleaded both, but did not press a damages case (no experts, no invoices/quotes for rectification), so the Tribunal proceeded on the restitution case (see 'THE POWARCHUKS MUST MAKE AN ELECTION...', paras [18]-[20]).
The counterclaim failed because BTH could not establish the value of labour performed (no timesheets/payroll evidence) and because the Tribunal found the owners were entitled to reject the work as worthless and uncertifiable, meaning BTH could not recover labour (see 'THE COUNTERCLAIM').
Before: The decision sits within established frameworks:
This decision: It applies existing statutory rules to the particular factual matrix and demonstrates how they operate together in VCAT:
After: Practitioners should note that in disputes where plumbing work is involved, clear documentary evidence about licensing and who carried out/supervised regulated work will be critical. The decision emphasises that VCAT will treat companies as contracting parties where invoices and payments point to the company. It also signals that VCAT will award restitutionary relief under ACL (Victoria) where a 'major failure' is established and that s 221HA may further penalise contractors who permit unlicensed plumbing.
"Because the Powarchuks claim for damages is inconsistent with their claim for restitution... they must make an election." (para 18)
"I accordingly find that the contract was formed ... with BTH ... and that the contract was not with Mr Kassab personally." (Formation, para 5)
"BTH ... has caused or permitted a person who is not permitted under Part12A ... to carry out that class of work in contravention of s221H(3)" (s 221HA discussion)
"I find that there has been 'a major failure' ... because the Powarchuks would not have acquired BTH's services if they had been fully acquainted with these matters." (ACL analysis)
Where this pattern exists, VCAT (and likely other tribunals) may find a 'major failure' under ACL (Victoria) and award restitutionary damages, and s 221HA may independently limit contractor entitlements.
As this is a VCAT decision issued in August 2023, later appellate treatment is not recorded in the judgment. The Tribunal relied on established authorities for legal propositions: Baltic Shipping Co v Dillon for the election principle (cited at para [18]); Jones v Dunkel for evidential inference principles (cited at para where failure to call witnesses is discussed), and Thurin v Krongold (VSCA) was cited concerning jurisdictional implications when invoking Commonwealth law directly in VCAT (para [31]). Practitioners should monitor appellate treatment if parties appeal VCAT decisions raising the interplay between s 221HA recovery in "a court of competent jurisdiction" and tribunal jurisdiction. The Tribunal expressly left that point open (see 'A jurisdictional issue').
Is VCAT 'a court of competent jurisdiction' for the purposes of s 221HA(3) of the Building Act? The Tribunal noted the point but made no ruling because it was not argued; in future disputes where parties contest tribunal jurisdiction for statutory disgorgement under s 221HA(3), appellate guidance would be desirable (see 'A jurisdictional issue').
The precise interplay and overlap between relief under s 221HA (Building Act) and s 267/268 (ACL Victoria) remains fact-sensitive. The Tribunal awarded restitution under ACL (Victoria) and noted s 221HA limitations; whether a claimant must pursue recovery under s 221HA in a court rather than under ACL in VCAT may be litigated.
Evidentiary standards for proving who supervised/plumbed the work: the Tribunal did not draw a Jones v Dunkel adverse inference, but the absence of licensing records or witness testimony was fatal to respondents' attempts to demonstrate lawful certification. Future cases may refine how tribunals weigh VBA registration evidence, employer records, subcontractor timesheets and compliance certificates.
To what extent does the finding that a product is an 'acceptable equivalent' hinge on supplier emails and the parties' contemporaneous acceptance (the MWJ Roofing email here influenced findings on which product was ordered and supplied)? Evidence chains for supplier communications will be crucial in material substitution disputes.
Practical takeaways: ensure clear documentary trails: who contracted, who was paid and into which account, who performed and supervised regulated work (with licenses), compliance certificates, and contemporaneous supplier documentation. Where owners seek restitution, pressing the damages alternative requires quantified, contemporaneous evidence of rectification cost.

DID THE POWARCHUKS REPUDIATE THE CONTRACT BY INTERFERING IN THE WORKS?
DID THE POWARCHUKS REPUDIATE THE CONTRACT BY UNLAWFULLY TERMINATING IT?
If you are not capable of finishing vba said you need to issue certificate of compliance for roof works done to date if you do not they will chase it up. Let us know if you are capable or not as need to start moving this job.
Hey mate. You step foot on my place police will be called.
I would like to resolve this matter by receiving a refund of payment and a compliance certificate of where the roof has been left. This decision has been made due to, Under the Australian Consumer Law, a service will be done with due care and skill, this guarantee means you must use an acceptable level of skill or technical knowledge when providing the service. This has not occurred, due to water leaking. As this is a major problem I would have not bought the service had I known beforehand the 'no experience in this service'. As a result I need to get someone else to remove all the wall cladding and tin roof to fix the job and pay for the entire job again, along with 8 weeks wasted with the $4000 cost of the cherry picker which needs to be hired again. The service was not achieved as it is normally suppose to and this problem cannot be fixed quickly or easily. (Sic)
(1) A consumer may take action under this section if:
(a) a person (the supplier) supplies, in trade or commerce, services to the consumer; and
(b) a guarantee that applies to the supply under Subdivision B of Division 1 of Part 3-2 is not complied with; ...
A failure to comply with a guarantee referred to in section 267(1)(b) that applies to a supply of services is a major failure if:
(a) the services would not have been acquired by a reasonable consumer fully acquainted with the nature and extent of the failure; or
(b) the services are substantially unfit for a purpose for which services of the same kind are commonly supplied and they cannot, easily and within a reasonable time, be remedied to make them fit for such a purpose; ...
If the failure to comply with the guarantee cannot be remedied or is a major failure, the consumer may:
(a) terminate the contract for the supply of the services; or
(b) by action against the supplier, recover compensation for any reduction in the value of the services below the price paid or payable by the consumer for the services.
The consumer may, by action against the supplier, recover damages for any loss or damage suffered by the consumer because of the failure to comply with the guarantee if it was reasonably foreseeable that the consumer would suffer such loss or damage as a result of such a failure.
Alternative claim for repudiation and damages at common law
Disposition of the claim for damages for defects
The invoices tabled on the second day of the hearing
I ordered and purchased Colorbond .55 interlocking wall cladding and received a cheaper and unsuitable product, to date the supplier has been unable to notify me with what the name of the product is. Durakote, which a few panels are yet most of the panels have no name. On 18th February 2020 MWJ cladding email to say the material supplied was a .42 High Tensile Steel supplied by Selection Steel called Monolith. After calling the supplier for MWJ, we have discovered and William from MJW has since said it is not this product and still cannot say what it is.
When initially approached by BTH construction in relation to this job, I sat down with him and discussed pricing and materials. We purchase, and offer, different steel suppliers and gauges for use in the roofing industry.
Disposition of the claim for reimbursement of the sum of $8,750 paid for materials
(a) the balance of the allegedly agreed payment for the installation of cladding and wall blanket: $9,250; > > (b) the cost of flashings, casings and other materials: $2,500; and > > (c) damages in respect of the loss of opportunity to complete the works: $2,500.
