Contribución a la historia de la libertad de expresión parlamentaria: el discurso de Tomás Moro como Speaker del Parlamento inglés de 1523

one of the most important and widespread freedoms accorded to members of a congress or parliament is the inviolability or irresponsibility on the opinions or statements issued in the exercise of their duties. this paper focuses on the constitutional recognition of this freedom of expression in english parliamentary law and the influence of a speech by the jurist, humanist and public man of the sixteenth century, thomas more, as speaker of the parliament summoned by henry viii 1523, which has been preserved thanks to the first biography written by his son-in-law, william roper. we conclude that, although it can not be said that thomas more is the founder of parliamentary privilege should be accorded the merit of having contributed to his subsequent consecration as rhetorical skills as argumentative, as shown in the speech. as an annex, provides a spanish translation of the text analyzed.
