he was not acknowledged as taking part in major legislative work or any related back-stage political haggling between different Francoist pressure groups. In 1960 he was involved in promoting so-called Fuero Recopilado de Navarra, a legislative attempt launched by Diputación Foral and aiming at consolidation of Navarrese civil code and its integration into the Spanish legal framework; he served as a liaison between the Navarros and Minister of Justice Iturmendi. Within the process he formally represented Pamplona lawyers, as he grew to dean of Colegio de Abogados of the Navarrese capital. As a lawyer he was also involved in a number of commercial enterprises, like Goysa-Walsh, Fuerzas Eléctricas de Navarra, El Irati and others. Last years In the early 1960s Don Carlos Hugo posed as a Francoist; his supporters pursued a policy of approaching the Falangist syndicalists, attempting to firmly mount the prince in political milieu of the regime and to enhance his chances of becoming a Francoist monarch in the future.

Following running of the bulls - with Don Carlos Hugo taking part in a carefully arranged publicity stunt – Arellano attended an evening cocktail party to honor the prince. However, events got out of control; young Huguistas, unaware of the plot, assaulted Arellano in the Tres Reyes hotel lobby, which terminated his brief rapprochement with the Javieristas. With his Cortes ticket renewed as Franco's appointee in 1961 and 1964, in the mid-1960s Arellano turned into a slightly more active member of the legislative. He entered Comisión de Leyes Fundamentales, discussed new Ley Organica del Movimiento and engaged in work on law on religious liberties; all of them were increasingly watering down authoritarian model of the regime, though Arellano was probably lacking sufficient political weight to engage in the backstage political wrestling. In 1966 Arellano received serious injuries in a traffic incident in Pamplona; apart from minor
