The Czech telecoms regulator the Czech Telecoms Office (CTU) has ordered fixed line operator Telefónica O2 to pay a further CZK43 million (USD1.96 million) to rival Tiscali relating to unpaid fees for dial-up internet services from 2005, Tiscali said in a statement. The watchdog has already ruled that the incumbent pay Tiscali CZK23 million for a similar reason. The former monopoly started to pay minimum fees determined by the regulator to ISPs offering dial-up services on its network from April 2005, instead of higher prices that were set in stone via contracts. Tiscali argues it is owed CZK70 million and says Telefónica O2 is also delinquent on paying its 2006 fees, despite the CTU verdict. Telefónica O2 says it is not possible to appeal the verdict with the CTU, but instead plans to file a lawsuit against Tiscali to have the decision overturned.
