GAS utility Slovenský Plynárenský Priemysel (SPP) is set to protest against the Supreme Court's verdict in the case of the so-called Ducký's bills of exchange. SPP cannot appeal against the verdict obliging it to redeem CZK350 million worth of bills of exchange to Czech Union Banka alone. It can only make use of a special appeal from the Prosecutor General's Office. Before requesting the office to do so, SPP had to wait until both parties involved in the dispute received the written verdict. Due to the fact that SPP does not know when exactly the second party in the dispute, Czech Union Banka, received the verdict, it is impossible to say when the term of 30 days to appeal began, SPP lawyer Ernest Valko said.
