Following the 03 August 2011 resignation of Juan Miguel F. Zubiri as Senator and the Manifestation and Motion filed by his counsel on 04 August 2011 praying that the said resignation be considered as a voluntary withdrawal and/or abandonment of his counter-protest, the Tribunal, on 11 August 2011, declared Aquilino L. Pimentel III as the 12th duly elected Senator of the Philippines during the 14 May 2007 National and Local Elections.

Having examined and appreciated a total of 384,680 ballots as well as Election Returns (ER) from Pimentel's protested precints, and corrected the manifest errors in the Statement of Votes (SOV), the Tribunal disclosed that Pimentel obtained 258,166 more votes than Zubiri in the contested senatorial race.
