Julian holds a tribunal at the city of Chalcedon, which is at this time a suburb of Constantinople, shortly after the death of Constantius.

Saturninius Secundus Salutius, who is raised to the rank of Praetorian Prefect, is given the chief oversight and with him are associated Claudius Mamertinus (another civilian), and four military commanders, Arbitio, Agilo, Nevitta and Jovinus.

The first two are ex-officers of Constantius, while the other two had served with Julian.

At this tribunal a large part of Constantius's ministers are brought to trial.

In charge of the daily inquisitions is Arbitio, "while the others were present merely for show" according to historian Ammianus Marcellinus.

Palladius, Taurus, Euagrius, Saturninus and Cyrinus are known to have been exiled.

Florentius, Ursulus and Eusebius are condemned to death.

Apodemius and Paulus Catena are even burned alive.

Another Florentius is imprisoned on a Dalmatian island.

As Constantius II died on October 5, 361, all this must have happened in late 361 and early 362.
