Attached is the judgement.
It considers the application of Ralli Bros principle in the context of US sanctions restricting payment by a UK broker to a UAE company sanctioned under US sanctions regarding Iran. The specific feature of the case is that it related to the transfer of trust monies, rather than the repayment of the debt.
It is an authority as to (among others) that the Ralli Bros defence will be available to what would be otherwise a breach of a contract, if the illegality affects the third-party necessary for the performance of the contract (e.g., a bank necessary to make a payment) and not the parties themselves.
It is also authority that the specific features of a contract (in this case, the obligation to transfer trust monies) may expand the scope of jurisdictions which will be covered by Ralli Bros principle.
