Southern Han is about timing, but timing in security of payment law is never a small detail. A contractor may have done real work and still lose the fast adjudication pathway if the payment claim does not meet the Act's statutory conditions.
The case has to be read carefully because security of payment legislation has been amended in some jurisdictions. For business owners, the evergreen lesson is to confirm the current legislation, the contract, the date work was done, the date the claim is served and whether the statutory preconditions are satisfied before pressing the button.
