Athenian slaves were the property of their master (or of the state), who could dispose of them as he saw fit. He could give, sell, rent, or bequeath them. A slave could have a spouse and child, but the slave family was not recognized by the state, and the master could scatter the family members at any time. Slaves had fewer judicial rights than citizens and were represented by their master in all judicial proceedings. A misdemeanour that would result in a fine for the free man would result in a flogging for the slave; the ratio seems to have been one lash for one drachma. With several minor exceptions, the testimony of a slave was not admissible except under torture. Slaves were tortured in trials because they often remained loyal to their master. A famous example of a trusty slave was Themistocles's Persian slave Sicinnus (the counterpart of Ephialtes of Trachis), who, despite his Persian origin, betrayed Xerxes and helped Athenians in the Battle of Salamis. Despite torture in trials, the Athenian slave was protected in an indirect way: if he was mistreated, the master could initiate litigation for damages and interest (δίκη βλάβης / dikē blabēs). Conversely, a master who excessively mistreated a slave could be prosecuted by any citizen (γραφὴ ὕβρεως / graphē hybreōs); this was not enacted for the sake of the slave, but to avoid violent excess (ὕβρις / hubris).Isocrates claimed that "not even the most worthless slave can be put to death without trial"; the master's power over his slave was not absolute. Draco's law apparently punished with death the murder of a slave; the underlying principle was: "was the crime such that, if it became more widespread, it would do serious harm to society?" The suit that could be brought against a slave's killer was not a suit for damages, as would be the case for the killing of cattle, but a δίκη φονική (dikē phonikē), demanding punishment for the religious pollution brought by the shedding of blood. In the 4th century BC, the suspect was judged by the Palladion, a court...
