Vincent "Bingbong" Crisologo is the incumbent. Crisologo, filed a case in the Quezon City Regional Trial Court (RTC) to disqualify candidate Vivienne Tan, who was reportedly not a natural-born Filipino. Tan, the daughter of business magnate Lucio Tan, migrated to the United States and became a naturalized American citizen on January 19, 1993. She returned to the Philippines in 1996 and has resided here since. Tan won in the RTC, but Crisologo appealed to the Court of Appeals, which disqualified Tan as "Not being a Filipino citizen at the time of her application to be registered as a voter on October 26, 2009 or at the time when her said application was approved by the [Commission on Elections] on November 16, 2009, Tan's inclusion in the voter’s list of Precinct 0853-A, Sto. Domingo, Quezon City, is therefore, highly irregular and downright invalid." The CA ruled in favor of Congressman Bingbong Crisologo Immigration Commissioner Marcelino Libanan certified that Tan re-acquired her Filipino citizenship only on December 1.
