An appeals court prosecutor heading a preliminary criminal investigation into alleged impropriety on the part of a former investigating magistrate who led a stock manipulation probe discussed the matter yesterday with Supreme Court prosecutor Evangelos Kroustallakis. Kroustallakis, a staunch anti-corruption campaigner, reportedly urged Georgios Koliokostas to pursue his probe at a rapid pace, saying claims such as those involving Constantina Bourboulia taint the entire judiciary body. Bourboulia, who resigned on health grounds last year, was allegedly conducting an affair, at the time of her investigation into the 1999 stock bubble, with a lawyer representing some of the firms she was investigating. Koliokostas will be looking into whether this may have influenced her conduct of the investigation, and how some of Bourboulia’s cases came to be closed hurriedly. Sources close to the investigation indicate Koliokostas has found indications of improper conduct, and charges could be pressed against Bourboulia in a matter of days.
