The Czech parliament's upper house on Wednesday adjourned a session on the European Union's reform treaty for at least one month, joining the lower house in a bid to postpone a vote on the pact. The 81-seat Senate voted 73-0 to return the treaty to committee negotiations. Four senators abstained. On Tuesday, the lower house put off a session on the so-called Lisbon Treaty to February 3. As a result the Czech Republic will not ratify the charter before the country's six-month rotating EU presidency starts January 1.
