The Appellant is a Thai company which (among other activities) trades in oil and gas.
The Respondent is a US-based company which specialises in the development and implementation of commodities trading software.
On 8 February 2013 the parties entered into a contract under which the Respondent agreed to provide software and software implementation services to the Appellant.
The contract provided for a total price of US$6,920,000 to be paid in instalments upon the achievement of nine "milestones".
It also provided for liquidated damages to be paid in the event of the Respondent's work being delayed, calculated at a daily rate "from the due date for delivery up to the date [the Appellant] accepts such work". The contract also provided for a cap on the Respondent's liability, but excluding both "specific remedies expressly identified as such in this Contract", and liability for "fraud, negligence, gross negligence or wilful misconduct". Work began in March 2013 and soon fell into difficulties.
A dispute arose over payments due and the Respondent suspended work in May 2014. On 25 March 2015 the Appellant terminated the contract; by this time, only the first two payment milestones had been achieved. Proceedings were commenced by the Respondent to claim sums it alleged were due in respect of software licence fees; the Appellant counterclaimed for liquidated damages for delay prior to termination and its costs arising out of the termination of the contract.

The Welfare Reform and Work Act 2016 imposed a limit of two on the number of children in respect of whom child tax credit (and its replacement, universal credit) is payable.
The limit applies, with a few exceptions, to all children born after 6 April 2017, when the new law came into force.The Appellants are members of families affected by this two child limit.
SC lives with her three youngest children, for whom she is solely responsible. Her youngest child was born on 11 July 2017 (and therefore after the two child limit took effect).
CB has five children, the youngest of whom was born on 19 April 2017 (just after the new legislation came into force).
The High Court dismissed the Appellants' claims, and the Court of Appeal dismissed their appeal.
The Appellants now appeal to the Supreme Court.
