Huguccio studied at Bologna, probably under Gandolphus, and taught canon law in the same city, perhaps in the school connected with the monastery of SS.
[2] Among his supposed pupils was Lotario de' Conti, afterwards Pope Innocent III, who held him in high esteem as is shown by the important cases which the pontiff submitted to him, traces of which still remain in the "Corpus Juris" (c. Coram, 34, X, I, 29).
Huguccio's work constitutes a sort of apogee that would influence not just the Anglo-Norman school but also, directly or indirectly, all later canon law (the bull Per venerabilem is a good example of this) and indeed the whole political and religious reality of Europe.
In relations between Church and Empire, Huguccio comes across as a partisan of the Holy See; thus, against the communis opinio, he alleged that clerics could not be brought before a lay court in feudal matters.
This identification of the two Huguccios as the same man dates back to a short biography compiled by the Italian historian Mauro Sarti, published posthumously in 1769.
