Earlier Tuesday, court president Leonel Castillo recommended [Reuters report] that the judges vote to approve a final tally that gave Calderon the lead by 233,831 votes. In earlier rulings, the court rejected most of Lopez Obrador's challenges [JURIST report], ruling there was no evidence of systematic fraud. The decision to certify Calderon as president-elect is final and cannot be appealed.
