With the end of Francoist Spain in 1977, Galicia became an autonomous community with Galician as its official language along with Spanish. It was then urgently required to establish a fixed standard form. As professor of Galician language and literature, Carballo Calero was appointed to lead the group of experts that should prepare the new norms for Galician. The first draft was produced in 1979 with the title "Normas ortográficas do idioma galego" ("Orthographic norms of the Galician language"). These norms recommended a gradual approach to Portuguese, using Portuguese as the most suitable orthographic reference for spoken Galician while allowing for a number of different solutions in case of doubt.
