With the
Empire, the law of treason was greatly expanded in scope, mainly in the reign of
Tiberius, and led to the rise of a class of professional informers, called
delatores. The concept of the emperor as divine had much to do with this. It became a maxim that treason was next to
sacrilege in gravity. The law as it existed in the time of Justinian is contained chiefly in the titles of the Digest and Codex
Ad legem Iuliam maiestatis. The definition given in the Digest (taken from
Ulpian) is this: ''
maiestatis crimen illud est quod adversus populum Romanum vel adversus securitatem eius committitur." ("The crime of majestas is that which is committed against the Roman people or against their safety.") Of treasons other than military offences, some of the more noticeable were the raising of an army or levying war without the command of the emperor, the questioning of the emperor's choice of a successor, the murder of (or conspiracy to murder) hostages or certain
magistrates of high rank, the occupation of public places, the meeting within the city of persons hostile to the state with weapons or stones, incitement to sedition or administration of unlawful oaths, release of prisoners justly confined, falsification of public documents, and failure of a provincial governor to quit his province at the expiration of his office or to deliver his army to his successor. The intention (
voluntas) was punishable as much as an
overt act (
effectus). "
Principes instar deorum esse" ("Emperors are as gods") are the words of
Tacitus. This crime was called
laesa maiestas divina in later law. It was not treason to repair a statue of the emperor which had decayed from age, to hit such a statue with a stone thrown by chance, to melt down such a statue if unconsecrated, to use mere verbal insults against the emperor, to fail in keeping an oath sworn by the emperor or to decide a case contrary to an imperial constitution. Treason was one of the
publica judicia,
i.e. one of those crimes in which any citizen was entitled to prosecute. The law deprived the accused in a charge of treason of his ordinary remedy for
malicious prosecution, and also took from him the privilege (which those accused of other crimes generally possessed) of immunity from accusation by women or infamous persons, from liability to be put to the torture, and from having his slaves
tortured to make them testify against him. ==Punishment==
