The boss of a firm that specialises in giving tax advice has won a Supreme Court fight with tax officials after featuring in newspaper articles about avoidance schemes.
Patrick McKenna, founder of the Ingenious Media group, had claimed that a senior official at HM Revenue & Customs (HMRC) abused his power when disclosing information to journalists.
He wanted a declaration that disclosures by David Hartnett were unlawful.
HMRC bosses disputed his claim.
A High Court judge and three Court of Appeal judges had ruled against Mr McKenna, but five Supreme Court justices have ruled in his favour after a hearing in London.
