1960-1961 course he spent the 1956-1964 period mostly pursuing research in Naples, with massive admin gimmicks on part of the University to find a legal framework for such a lengthy stay. Since 1964 he worked under the dedicación exclusiva contract. In 1969 nominated consejero honorario del Consejo Nacional de Educación, though his academic relations with the Francoist education authorities remained thorny. Since the early 1970s Tejada intended to move to Madrid, but his 1971 and 1974 bids for Complutense failed. His 1975 bid for Universidad Autónoma took an awkward turn, when Tejada challenged the referees appointed as linguistically incompetent. His protest was dismissed and in 1976 he lost to Elías Díaz García, appealing the decision; the issue was not settled before his death. However, in 1977 he was appointed with no contest to cátedra de Derecho Natural y Filosofía del Derecho at Complutense; death interrupted his first course in Madrid. Though member of a number of scientific institutions around the world, recipient of a few doctor honoris causa titles, a vastly prolific author and during his lifetime himself subject of 4 PhD dissertations, Tejada did not make it to the top elite of Spanish law scholars and did not enter Real Academia de Jurisprudencia y Legislación. There are conflicting accounts of his standing in the academic realm. Some claim that he was universally highly regarded as doctrinally intransigent but pro-student open-minded, tolerant scholar, as demonstrated by his supervision of PhD bid of Enrique Tierno Galván, the future key PSOE politician. Others present him as a feared ”inquisidor”, extremely quarrelsome hypocrite pursuing private goals and eager to call security when dealing with manifestations of student dissent towards him. Theorist of law Tejada is considered member of the natural law school and its key representative during the Franco era, influenced by early modern Spanish jurists like Francisco Suarez but mostly following the Aquinas; he regarded own work merely a gloss to the opus of St. Thomas. Hence, within iusnaturalismo he is classified as representative of Neo-Scholastic school, as opposed to Axiological, Neo-Kantian and Innovative Natural Law schools. Together with Michel Villey deemed a renovator of classical European iusnaturalismo of the mid-20th century, Tejada clearly distinguished own vision from "iusnaturalismo racionalista". Within this framework, he agreed that the role of jurisprudence was discovering rather than inventing. Tejada's work consisted of systematizing concepts falling into ontology, anthropology, logic and axiology. His original contribution was
