Philip Marshall QC, Jonathan Harris QC (Hon.) and James Mather are acting for Abu Dhabi Commercial Bank in State of Qatar v Emirates NBD Bank, one of the largest claims to be brought in the English High Court, in which claims are brought against the bank by the State of Qatar in conspiracy said to arise out of an alleged international scheme to manipulate the value of Qatari currency and bonds connected with the so-called ‘blockade’ of Qatar by neighbouring Gulf states causing the Qatari Central Bank to have to deposit US$13 billion.
