In 1150, a court was held in the presence of King Roger II by Florius, fellow justiciar Lampus de Fasanella, and the chamberlain Atenulf in Salerno.
[3] In 1158, in the castle of Capua, Florius and fellow justiciar Aimeric of Montemore adjudicated a complaint from the abbot of Santa Sofia of Benevento.
[3] Around 1166, at Aversa, Florius, with the justiciars Matthew de Venabulo and John de Valle, "performing the role of the lord king [in a] plenary and solemn court" (plenariam et sollempnem curia), restored two mills to the Diocese of Aversa.
This prompted Pope Alexander III to request King Louis VII of France to intervene on Florius' behalf with King William II of Sicily and, if this failed, with the Byzantine emperor Manuel II Comnenus.
[6] In 1178, Florius and Lucas Guarna returned to Salerno and, with Eugenius of Palermo, presided over an inquiry into the murder of an abbot.
