Conclusive certificates are rebuttable. Sections 23 and 27 give the Chief Executive Officer of ABA the power to certify whether specified property or liabilities formed part of the undertaking, and make such certificates conclusive evidence in all courts and tribunals, "except so far as the contrary is established" (s 27(1)). That creates administrative convenience, but the "except" clause preserves a margin for challenge. Parties cannot simply rely on a certificate as absolutely indefeasible , a contrary case can be made, and the text allows for the possibility of contradicting evidence or argument.
Accrued interest and fees are mostly excluded. Section 4(2)(a) and (b) exclude accrued but unpaid interest, costs, fees or charges in respect of financial accommodation, and accrued but unpaid interest on deposits, from the undertaking. That means accrued interest that depositors or creditors might have assumed would transfer to ABA could remain as an obligation of CAB. Lenders, depositors and receivers should check whether interest components form part of the transferred undertaking before assuming they can enforce them against ABA.
Future advances subject to agreement. A security that extended to future advances vests in ABA, but post-vesting that extension is "subject to any agreement between ABA and that person" (s 12(2)). In practical terms, debtors and secured creditors should be aware that future lending previously secured by CAB may not automatically be available from ABA on the same terms unless ABA and the debtor reach agreement.
Superannuation and benefit funds excluded. Section 8(2) excludes instruments relating to provident, benefit, superannuation or retirement funds from the substitution rule. That can generate surprises when parties assume all contractual positions were automatically transferred. Practitioners must review pension and employee benefits instruments separately.
Third parties need not inquire, but risk remains. Sections 22 and 24 relieve third parties, registrars and title offices from having to see or inquire whether property formed part of the undertaking. That reduces due diligence burdens for persons dealing with ABA. However, s 22(3) preserves ABA’s liability to CAB for anything done or purporting to be done by ABA in relation to property not part of the undertaking. Third parties relying on statutory non-inquiry should still consider the consequences if instruments mistakenly relate to property outside the undertaking.
Service mechanics change with corporate status. Section 21 makes service on ABA taken as service on CAB and vice versa while CAB remains a subsidiary of ABA within the meaning of Corporations Law s 9. Those mutual service rules cease to have effect on CAB ceasing to be such a subsidiary (s 21(2)-(3)). Parties relying on service by delivering to one company should monitor the corporate relationship, because service protocols will change once CAB is no longer a subsidiary.
Exemption from taxes and charges has an explicit exception. Section 29 broadly exempts instruments and acts connected with the operation of the Act from tax and charges, but expressly excludes Registrar-General fees relating to land (s 29(2)). Land transactions may therefore still attract fees, stamp duty or registration charges from the land registry, depending on local practice, despite the broader exemption.
No automatic transfer of office-holders. Section 8(3) makes clear that a director, secretary or auditor of CAB is not by virtue of the Act a director, secretary or auditor of ABA. Corporate governance positions must be dealt with under corporate law and internal processes. Surprises may occur if stakeholders assume officials carry over automatically.
Obligations from ABA to CAB excluded. Section 4(2)(c) excludes obligations of CAB relating to financial accommodation provided by ABA to CAB. Financial arrangements where ABA had advanced to CAB do not transfer back to ABA as obligations of the undertaking. Parties should map inter-company obligations carefully.
Limited statutory enforcement detail. The Act sets out the mechanics for vesting and administrative acceptance, but it does not create bespoke penalty regimes or detailed enforcement processes for registries that do not act in accordance with the Act. Where a registrar or authority fails to act on a CEO certificate, the statutory remedies are those of general law and administrative law rather than special statutory sanctions in this Act.
Schedule 1 linkage. Schedule 1 lists earlier building societies and related bodies the undertaking of which had by operation of law been vested in the listed societies. That historical linkage may affect title and claim chains, but practitioners should be cautious: the Schedule does not itself explain prior instruments, and tracing rights across multiple statutory vestings may require documentary searches.
Services and negotiable instruments. Negotiable instruments and orders for payment expressed to be drawn by, on, or given to CAB have the same effect as if drawn by, on, or given to ABA (s 15). Banks, payees and intermediaries should ensure payment instructions, clearing arrangements and reconciliation are aligned with ABA’s systems on and after the appointed day.
