Clifford Stanford, the founder of Demon and Redbus, went on trial on Tuesday over charges of unlawful email interception.
The trial at Southwark Crown Court began with the counsel for the defence asking for the judge to rule on certain legal arguments. A jury is unlikely to be called before Wednesday.
Stanford has been charged under The Regulation of Investigatory Powers Act (RIPA) 2000, which states that it is an offence to intentionally intercept emails without lawful authority.
Stanford was charged with intercepting email correspondence from John Porter, former chairman of Redbus Interhouse, and son of Dame Shirley Porter. Facing the same charge is George Liddell, a former employee of Redbus.
