The Czech Republic’s Constitutional Court is to begin considering today what is likely to be the last legal objection to the EU’s Lisbon Treaty.17 senators, backed by President Vaclav Klaus, are complaining it will infinge Czech national sovereignty. Although the Czech parliament has already approved the treaty, Klaus has yet to sign it. The senators want the court to decide if the treaty forms the legal foundations for the creation of a European superstate. If it does then it violates the Czech constitution. Klaus has already asked for some guarantees from the Swedish EU presidency for an exemption from part of a Rights Charter.That exception has yet to be approved by the other 26 member states. Klaus feared that ratifying the treaty in its current form would expose his country to claims for property that was taken from three million ethnic Germans who were expelled from Czechoslovakia after the second World War. All 27 EU members must approve the treaty for it to be effective – a ruling from the Czech Constitutional Court is not expected today.
