Eufranio Eriguel

During his term as Mayor, Eriguel was involved in the construction of a commercial building within the premises of the town plaza [9][10]—a redevelopment which the Supreme Court later ruled to be "irregular"[9] in the "Land Bank of the Philippines v. Cacayuran" ruling.[9][10][11] The decision "penalizes abusive municipal officials"[10] even beyond their terms, and is considered a landmark case in Philippine jurisprudence.[10] However, the court later granted a motion for reconsideration regarding the case on May 15, 2015, because the Municipality of Agoo had not been impleaded in the original case.[12]

Another redevelopment which took place was the partial conversion of the Museo de Iloko into a franchise of fastfood giant Chowking.[11] The Don Eufemio F. Eriguel Memorial National High School, named after Eriguel's father, was also established during his term.

Eriguel was succeeded by his wife Sandra as Mayor in 2007. Eriguel was then appointed as an adviser to the provincial government of La Union for municipal affairs—a post he held until June 30, 2010.[4]

On June 11, 2014, Eriguel filed House Bill 4644 in an attempt to create a new city in the Second District of La Union by merging the municipalities of Agoo and Aringay.[16] The bill was co-authored by Eriguel's allies, La Union first district Rep. Victor Ortega and Abono party-list Rep. Francisco Emmanuelle Ortega III.[16] The bill would have created the "City of Agoo-Aringay," having two districts under a mayor and vice mayor along with 14 councilors in the Sangguniang Panlungsod,[16] all of which were "new" positions for which the former municipal officials could run despite having finished the terms limits of their offices.[17] The purpose of the bill was to increase the Internal Revenue Allotment (IRA) received by the cities, so they could build more infrastructure, gain various employment and businesses, increase recreational activities, and among other benefits.[18][19]

During his term Eriguel started festivals and events to solidify Agoo's rich culture and help its economy and tourism. The Dinengdeng festival, which was first celebrated in 2005, has been celebrated continuously to this day.[20] The Kilawen festival, which was an idea he shared with his wife, Sandra Eriguel, was first celebrated on December 28, 2011.[21]

In 2013, Eriguel was awarded the Saranay Award for his outstanding service during his time as a mayor and congressman.[22] The Saranay Award is given to those with the “highest degree of excellence in their chosen fields.”[23]

Eriguel's caravan was involved in a bombing incident, believed to be an assassination attempt, on April 30, 2016, in Agoo, La Union. The incident claimed the life of his driver, Jiovannie “Dalmas” Cacayuran and seriously injured eight (8) other individuals including his Aide, Samuel Ofiaza who lost his right eye.[24]

On August 16, 2016, Eriguel was included by Philippine President Rodrigo Duterte as one of the local government officials and legislators allegedly involved in illegal drug trade[25] in his "I am sorry for my country" speech.[26][27] Eriguel and other La Union politicians denied these allegations.[28] In the last part of March 2017, Eriguel and three other La Union politicians were removed from the narco-politician list.[29][30] A news report quoted sources saying that the inclusion of Eriguel in the narco-politician list was politically motivated. The reporter said there were several personalities close to those in charge of providing the list to the President who have taken advantage of the situation to include the names of their rival politicians.[31]

On June 17, 2018, Eriguel, who had been a founding force in former Vice President Jejomar Binay's United Nationalist Alliance, was sworn into the ruling PDP–Laban party by Speaker Pantaleon Alvarez.
