However, this approximation to Portuguese was perceived by some pro-Spanish conservative groups as a possible political stance. Consequently, the norms were revoked without Carballo's consent by means of a special law (the "Decreto Filgueira"). In light of those events, Carballo Calero resigned his position in 1980. A new set of norms was passed in 1982 by the newly created "Instituto Galego da Lingua" ("Galician Institute for the Language") and the Royal Galician Academy, of which he was still a member. Carballo Calero had by then helped to create the Galician Association for the Language (1981) to counteract what he thought to be an attempt to "damage" the language.
