イタリア共和国憲法
Facchinetti proposed to formalize "Il Canto degli Italiani" in the Constitution of Italy, in preparation at that time, but without success. The Constitution, which came into force in 1948, sanctioned, in article 12, the use of the flag of Italy as a national flag, but did not establish what the national anthem would be, nor even the national symbol of Italy, which was later adopted by legislative decree dated 5 May 1948.
