WARSAW, October 30 (RIA Novosti) -- Czech President Vaclav Klaus said on Friday he was satisfied with the EU leaders' concession to his demands and would set no more conditions for the country's ratification of the ambitious EU reform treaty.

The reform treaty, also known as the Lisbon Treaty, is an international agreement signed in Lisbon on December 13, 2007 which is expected to change the workings of the European Union.

The Czech Republic alone has so far refused to ratify the document, which needs the approval of all 27 EU members to take effect.

Klaus has demanded, among other things, an opt-out for his country from the EU Charter of Fundamental Rights over fears of property claims by Germans expelled after WWII and asked the Czech Constitutional Court to review the treaty to see whether it conforms to the country's constitution.

He said earlier he would not sign the ratification until the Constitutional Court made a decision, citing the reform treaty as a threat to the country's national sovereignty in its current form. The court is expected to rule on the treaty on November 3.
