A High Court judge in London ruled in favour of creditors in a case regarding the validity of the purchase undertaking for about $700 million of sukuk issued by Dana Gas. The idea that Dana Gas has been able to assert for the past five months that its own sukuk were non-sharia-compliant has struck many observers as unusual. Judge George Leggatt said that Dana Gas' challenges to the validity and enforceability of the purchase undertaking were unfounded and declared the purchase undertaking for Dana's sukuk as valid and enforceable.
