Credit Suisse, UAE-Lebanese Privinvest and others argued that a lack of "adequate" disclosure jeopardised a fair trial.
Under English litigation rules, each party has to disclose documents on which they rely for their case, those that might damage their own case and those that support the case of others.

Credit Suisse agreed to pay about $475 million to British and U.S. authorities in 2021 to resolve bribery and fraud charges and has pledged to forgive $200 million of debt owed by Mozambique.
