Top Bosnia court orders release of president, charged with graft SARAJEVO (Reuters) - Bosnia's Constitutional Court ruled on Friday that the president of the autonomous Muslim-Croat federation, charged with corruption, had been detained illegally, and ordered a lower court to release him immediately. Zivko Budimir was arrested along with 19 other officials in late April in the most high-profile anti-corruption drive in Bosnia since independence more than two decades ago. A court ordered Budimir and his co-accused aide to be kept in detention because they held Croatian passports and there was a risk they might try to flee. Budimir has been charged with accepting bribes to grant amnesty to a number of convicts. "The case has been returned to the (state) court, which is obliged to make a new decision immediately in line with the Constitution and the European Convention on Human Rights," the Constitutional Court said in a statement. Budimir's lawyer Ragib Hadzic said the court had determined there were no grounds to keep him in custody while the investigation was underway. The arrest of Budimir has exacerbated a political crisis that blew up last year when he refused to approve a Federation government reshuffle and the appointment of judges to the Constitutional Court. Bosnian Prime Minister Vjekoslav Bevanda said this week that a failure by Budimir to sign a law cutting military pensions might delay the International Monetary Fund's release of the next tranche of a loan.
