Fiona owns and operates 'Fiona's Futons' (an importer of bedroom furniture and accessories located in Fremantle, Western Australia). Fiona ordered 20,000 queen size futon mattresses from Jaki, a sole trader and exporter of mattresses located in Yokohama, Japan. The mattresses were to be delivered to Fiona's business premises in two instalment shipments of 10.000 mattresses each: The first instalment on board The Pacifica in July (the July shipment) and the second on board The Oceania in November (the November shipment). The parties have incorporated a clause into their contract that the law of Australia (or Western Australia, as applicable) shall be the governing law should a dispute arise.

The following issues arose:

1: The July shipment contained only 8,000 mattresses (instead of the contracted 10,000 mattresses).

Discuss one principle (pertaining to one source) of law Fiona may be able to rely upon to obtain a remedy. Also briefly outline possible remedies, if any.
