An estimated 900,000 registered Filipino overseas absentee voters  (OAVs) will have a full month before the May elections to cast their votes. 
The Commission on Elections (Comelec) released En Banc Resolution 9618 which mandates that “casting of votes (for OAVs) shall be for a period of thirty calendar days beginning at eight o’clock in the morning of April 13, 2013 local time of the host country until seven o’clock in the evening of May 13, 2013, Philippine time inclusive of all established holidays in the Philippines  and such other holidays  in host countries.”
OAVs are allowed to vote only for candidates running for national positions, including party-list organizations, using the manual mode of voting.
The poll body also disclosed that it has delisted 200,000 OAVs from the official voters list for failing to file the mandatory manifestation of intent to vote.
Comelec Chairman Sixto Brillantes Jr., said they have asked 238,557 OAVs who failed to cast their votes for the last two consecutive elections to file their manifestation of intent to vote  for the May polls or face being delisted. Brillantes said only 29 responded so they had no choice but to delist more than 200,000 OAVs.
He said said it was important for the poll body to determine the number of OAVs determine the number of ballots to be printed. “Imagine if we are to print say 978,000 ballots and then more than 200,000 will not vote,” Brillantes said.
Comelec had earlier issued Resolution 9567 stating that OAVs who fail to participate in two elections shall be deemed removed from the National Registry of Overseas Absentee Voters.
