The June 20 resolution of the poll bodys second division has been mailed, the mayors office said.
In their electoral protest, Domingo and her running mate, Eligio Lagman, alleged massive cheating in the local polls.
Rodriguez ran under the banner of the Lakas-NUCD party, while Domingo ran as an independent candidate. In its recount, the Comelec said Rodriguez garnered 27,304 votes as against Domingos 22,010.
Before he became city mayor, Rodriguez served as third district congressman for three terms. He was part of the prosecution panel in the impeachment trial of former President Joseph Estrada.
City Hall employees congratulated Rodriguez upon learning about the Comelec resolution, some of them issuing a statement citing him for his "excellent urban governance."
Last year, Rodriguez was selected as third runner-up in the World Mayor Search, while San Fernando was named as "most competitive mid-sized city." Ding Cervantes
