This would speed things up greatly but I fear for places where people are running against the incumbent this will test the the determination and honor of the local comelec officials. This would also level the playing field for candidates with less money (read:: less corrupt) because incumbents have enough cash to put lawyers in each clustered precinct. Local politicians usually use the lawyers to slow the pace of voting in the precincts whose voters they do not own. In some ways you can think of these lawyers as thugs or as protectors of the sanctity of the ballot because they either impede you or protect your vote, a true double edged sword.

Candidates can no longer complain about possible anomalous election documents at the precinct level and instead, wait for the winners to be proclaimed first, according to new rules promulgated by the Commission on Elections (Comelec) over the weekend.
Comelec Resolution 8804 says that candidates, political parties, and party-list groups can only question documents that they deem to be suspicious – such as election results, for instance – and challenge the results before the proclamation of winners if there is an “illegal composition of the board of canvassers (BOC)” and “illegal proceedings of the BOC.”
