The president of the German Federal Constitutional Court, Andreas Vosskuhle, sits in a court room in Karlsruhe, southern Germany, Tuesday July 10, 2012. Germany's highest court is to hear arguments Tuesday against the country signing up to the Europe's emergency bailout fund and a new treaty limiting debt. Opponents of the treaties argue that joining the bailout fund and debt pact for the 17 countries that use the euro would impose limits on the German Parliament's constitutional power to say how taxpayer money is spent. Parliament ratified the treaties June 29 but President Joachim Gauck has held off signing them into law while the court hears the objections. The Federal Constitutional Court is being asked to issue a temporary order blocking Gauck from signing while it fully considers the case, which court officials have said could take several weeks.
