South East Water Limited, R (on the application of) v Water Services Regulation Authority

SEW failed to establish pressing grounds or exceptional circumstances justifying interim relief. The harm to SEW from publication is outweighed by the public interest, harm to customers, and the interests of lenders and investors. The statutory and case law framework sets a high threshold for restraining publication by a regulator, which SEW did not meet.
