This is one of those cases every equipment supplier should read in spirit, even if the facts are bigger than a typical small-business transaction. The supplier had real assets in the customer's hands. The problem was that the PPSR timing and PMSI perfection rules had not been handled properly.
The Court accepted that the delay was caused by accident or inadvertence and granted relief. That was a good outcome for the supplier, but the case is not a permission slip to be casual. Court relief costs money, takes time and depends on evidence. If another creditor is prejudiced, the result can be very different.
For small businesses, the system should be simple: if you sell goods on retention of title, lease equipment, finance assets, consign stock or supply valuable equipment on credit, PPSR registration should happen as part of deal setup. It should not depend on one person remembering a legal rule they were never trained on.
