Unable to receive instruction or support from the empire, the provincial Byzantine magistrates, who were known as iudices (meaning "judges"; the Latin word evolved into the medieval Sardinian "Judicados"), continued to rule autonomously. As in the other Sardinian provinces, what were initially appointed, perhaps even elected, positions in Gallura eventually evolved into hereditary ones.
Lacking support from the imperial authority, the local Byzantine officials, referred to as judges, maintained their autonomy. Similar to other Sardinian regions, initial appointments in Gallura may have been made by election, but later evolved into hereditary positions.
