The available reasons trace the parties' communications in some detail. On 1 October 2021, a consultant for Australian Steel emailed Selection Steel about APT's future requirements and referred to adopting terms used in the past, including 90 days end of month from delivery. That email also referred to a strategic long term partnership.
On 26 October 2021, Australian Steel's purchasing officer sent Selection Steel a purchase order for four variants and quantities of hot rolled steel, with a total purchase price of $816,205.70 including GST. Attached to that email were APT's terms and conditions of trade. Those terms were drafted strongly in APT's favour. They said APT's conditions applied to each contract, excluded supplier terms unless APT agreed otherwise in writing, and would prevail over inconsistent supplier terms. They also dealt with delivery timing, liquidated damages for delay, payment timing, set-off, suspension of payment for breach and indemnity rights.
On 28 October 2021, Selection Steel's general manager finance responded by email saying APT's supplier terms were relevant to dealings with BlueScope and did not apply to Selection Steel. He asked for confirmation that Selection Steel Trading's terms and conditions would apply for future trading and supersede APT's terms. Australian Steel's CEO then replied that Selection Steel's terms and conditions would be used.
The complication is that there was then an alleged further email sent six minutes later. According to Australian Steel, that later email clarified that Selection Steel's terms applied specifically to slitting invoices, while coil supply would be subject to APT's terms. Australian Steel relied on evidence from an IT consultant and a consultant who said the email existed and was received. Selection Steel relied on evidence that searches of its server and archives did not show the email in the relevant histories. O'Bryan J said the evidence was not conclusive and the court was not in a position to resolve whether that email was sent and received on the application.
The reasons also record that on 15 February 2022 Australian Steel executed Selection Steel's application for commercial credit and a declaration accepting Selection Steel's terms and conditions of sale. That document was obviously important to Selection Steel's case, because suppliers often rely on signed credit applications as the clearest evidence that their terms govern ongoing supply on account. But the existence of that signed document did not automatically end the matter. The earlier communications and the disputed email trail still mattered to the court's assessment of whether there was a genuine dispute or offsetting claim for s 459H purposes.
