Read more about Klaus and the Lisbon Treaty.
Klaus has been concerned about 2.5 million ethnic Germans who were expelled from Czechoslovakia after WW2, attempting to reclaim their properties.
As such, he and a group of senators posted a legal challenge to the Czech constitutional court, which is expected to give its decision on 27th October 2009.
Klaus cannot sign before the ruling is delivered and if the legal challenge is rejected, Klaus might have to sign - unless he can find another way to hold up ratification.
