MUMBAI, India - India's Supreme Court has rejected an appeal by Vijay Mallya for charges against him of violating foreign exchange rules to be dropped, adding to the legal challenges facing one of the country's most prominent businessmen.The country's enforcement directorate, responsible for fighting financial crime, says Mallya entered into an unauthorised agreement in 1995 to advertise Kingfisher beer on F1 cars from 1996-1998.ADVERTISED WITHOUT PERMISSION Mallya is chairman of United Breweries which makes Kingfisher beer and is now around 40%-owned by Dutch brewer Heineken. The directorate has said he did the advertising deal without seeking permission from the central bank.Such clearance would have been needed because the agreement involved money going out of India.Lawyers for Mallya, who is also under pressure from lenders to repay dues linked to his grounded carrier Kingfisher Airlines, had told the court that the non-compliance was neither deliberate nor willful, according to the court documents.READ: Mallya: Bernie must help improve F1 image India's highest court on Monday (July 13) rejected the appeal in the long-running case and could now force Mallya to face the enforcement directorate charges.
