Electronic ballot boxes made in Brazil and used by Paraguay in past elections, sit in disuse under lock in a deposit at the Electoral Justice Board as officials prepared cardboard boxes and paper ballots to be used in Sunday's presidential election, in Asuncion April 19, 2008. The opposition parties that will face off against the ruling Colorado Party acquired a court order to prohibit electronic voting and revert back to the use of paper ballots. Voters will decide on Sunday whether or not to end the 61-year reign for the Colorado Party, the world's longest-ruling political party still in power. REUTERS/Rickey Rogers (PARAGUAY)
