Czech President Vaclav Klaus Wednesday ratified a treaty establishing the International Criminal Court (ICC), a tribunal set up to punish war crimes and genocide, dpa quoted his office as announcing. The Czech Republic was the last member of the 27-strong European Union to join The Hague-based court. The president took over eight months to ratify the tribunal's founding treaty which cleared parliament's lower house on October 29. The upper house, the Senate, approved the charter in July 2008. The Czech Republic signed the treaty, adopted in Rome in 1999. The charter entered into force in 2002.
