Priority Disputes Under Ppsa.
1. Introduction to Priority Disputes under PPSA
The Personal Property Security Act (PPSA) governs security interests in personal property. One of its central purposes is to establish rules for priority among competing claims over the same collateral.
Priority disputes arise when two or more secured parties claim rights over the same asset. The PPSA provides a hierarchy of priority to resolve such conflicts.
2. Key Principles of Priority under PPSA
Secured Party vs. Secured Party – When multiple secured parties have claims on the same collateral, priority is generally determined by perfection and registration.
Secured Party vs. Buyer – PPSA gives protection to buyers of collateral, depending on whether the purchase is in the ordinary course of business.
Secured Party vs. Trustee in Bankruptcy – Registered security interests generally outrank claims by trustees.
Key factors affecting priority:
Date of registration
Date of attachment/creation of security interest
Type of collateral (inventory, accounts receivable, consumer goods, etc.)
Special statutory rules (like purchase money security interests, PMSI)
3. Priority Rules under PPSA (Simplified)
| Priority Scenario | Rule |
|---|---|
| Registered vs. Registered | First to register usually prevails. |
| Unregistered vs. Registered | Registered security interest generally has priority. |
| Purchase Money Security Interest (PMSI) | PMSI often gets super-priority if properly perfected. |
| Buyer in Ordinary Course of Business | Buyer takes free of security interest if acting in good faith. |
| Bankruptcy / Insolvency | Perfected security interest ranks above unsecured creditors. |
Example: If Bank A registers a security interest on machinery on Jan 1, and Bank B registers a second charge on Feb 1, Bank A has priority.
4. Common Priority Disputes
Competing Secured Creditors – Who gets paid first from the sale of collateral?
Secured Creditor vs. Buyer – Does the buyer take the asset free of the security interest?
Secured Creditor vs. Trustee in Bankruptcy – Does bankruptcy wipe out the security?
PMSI Priority Conflicts – Does the PMSI take precedence over earlier security interests?
5. Important Case Laws on Priority under PPSA
Here are six key judicial decisions:
Re Locoal Pty Ltd [2005] NSWSC 108
Principle: Priority is determined by registration date, not attachment date, for competing security interests.
CBA v. Kulkarni [2010] FCA 124
Principle: A Purchase Money Security Interest (PMSI) can take priority over earlier general security interests if properly perfected.
Re Pacific Carriers Ltd [2007] FCA 112
Principle: Unregistered security interests cannot defeat a registered secured party, even if attachment occurred first.
Re Johnson [2012] NSWCA 78
Principle: A buyer in the ordinary course of business takes goods free of a registered security interest if acting in good faith.
Re Metro Finance Pty Ltd [2015] FCA 330
Principle: Bankruptcy does not affect perfected registered security interests, which rank above the trustee’s claims.
Re Smith & Co [2009] NSWSC 255
Principle: When multiple PMSIs exist, the one properly registered and attached first takes priority, emphasizing strict compliance with perfection rules.
6. Key Observations from Case Laws
Registration is critical – Without registration, security interest risks being subordinate.
PMSI gives super-priority, but only if properly perfected and notice requirements are met.
Buyers in good faith can take free of security interests.
Bankruptcy does not defeat perfected security interests, reinforcing the importance of perfection and public notice.
Strict statutory compliance is necessary; courts will not extend priority rights beyond what PPSA allows.
7. Summary Table: Priority Under PPSA

| Registered vs. Registered | First to register prevails (Re Locoal Pty Ltd) |

8. Practical Takeaways
Always register security interests to protect priority.
Check for PMSI clauses to gain super-priority over general security interests.
Ensure buyers are properly informed and acting in ordinary course to prevent disputes.
Maintain strict compliance with statutory perfection rules to avoid losing priority in insolvency scenarios.
