The recent move by Dana Gas to declare its approximately US$700 million of outstanding trust certificates unlawful has been a troubling development for the Islamic finance industry. Dana Gas has initiated proceedings in the UAE to declare the sukuk illegal and has secured a series of injunctions preventing enforcement by creditors, but the key question remains unanswered. That is whether non-compliance with Shari'a principles would have any bearing on the legal enforceability of these instruments. Any judgment in favour of Dana Gas could have wide ranging implications on the sukuk market. White & Case LLP argue that the concept of Shari'a-compliance should be treated as distinct from legal enforceability. Dar Al Sharia Legal & Financial Consultancy issued a pronouncement on the Shari'a-compliance of Dana Gas' sukuk at the time the sukuk were issued. Pronouncements of such nature are generally not open to retroactive invalidation as is being sought by Dana Gas.
