The possibility of establishing a single autonomous statute for the Southern Basque Country was again explored and provided for in the late 1970s, but strong political objections both in the Spanish establishment (UCD) and Navarre (Unión del Pueblo Navarro party founded, swing in Spanish Socialist Workers' Party's position) drew the project to a stalemate. The continuation of the institutional framework inherited from the dictatorship in Navarre (the "Amejoramiento", "the Betterment") was coupled with a staunch opposition staged by the ruling circles to a change in Navarre (attacks of Montejurra, removal from office of Javier Erice as mayor of Pamplona in 1976) amidst a climate of violence (ETA, police forces, state sponsored paramilitary groups, etc.).
