The uncertainty stems from the fact that the Czech constitutional court is examining a legal challenge to the Lisbon Treaty, lodged by senators close to Mr Klaus. It is unclear how quickly the court will make its decision and, if the decision is positive, how much later Mr Klaus would then sign the treaty, completing ratification.
Time is pressing because the current commission's mandate expires at the end of October, as does the post of the current high representative for foreign affairs, held by Javier Solana.
The Swedish presidency is nervous about entering uncharted legal territory. It can either keep the commission as a caretaker, but ineffectual, executive, or try to set up a new commission under the Lisbon Treaty rules. Another option would be to negotiate a new commission with the current rules, but that would mean unwanted negotiations on reducing its size.
