The dispute arose from a 2008 deal where Kuwait Finance House agreed to provide funding of US$3 million to Canterbury, which was in financial strife at the time, and structured in a way that it didn't involve interest, so it was compliant with Islamic law, and wasn't a direct investment.
Teece would buy commodities from the investment firm, then on-sell them to Canterbury, which would sell them back to Kuwait Finance House.
Canterbury was put in receivership in mid-2009 without paying any cash to either Teece or Kuwait Finance House, and the investment firm then advised Teece it might seek to enforce the agreement against him.
In 2011, it filed a claim against Teece in the Bahrain chamber, which ruled against him in February 2012.
Because Judge Matthews ruled the chamber wasn't a court, he didn't have to decide if it had jurisdiction over the dispute, whether its ruling was natural justice, or if it should be enforced in NZ.
