Treason

There is more information available on this subject at Treason on the English Wikipedia.

Treason is a legal concept referring to the betrayal of a state authority to which one owes allegiance. It especially refers to such betrayal as through making war on the state, giving aid to the enemies of the state, or attacking the head of state. Persons who defect from one state to another may also be considered guilty of treason. Sedition, the inciting of civil unrest or insurrection, is also frequently considered treasonous. Colloquially, treason is often used for any perceived act of disloyalty or betrayal. A person who commits treason is known as a traitor.

Treason is a crime within the Unified Earth Government and United Nations Space Command. Commiting treason during wartime is a capital offence. Major Standish claimed that the penalty is permanent induced coma, with the injection publicly broadcast. According to JAG 845-P and JAG 7556-L, violation of the Cole Protocol is treason and is punishable by life imprisonment or execution. Violation of the confidentiality of certain ONI transmissions is also considered an act of treason and is punishable by death.

The group Sapien Sunrise considered UEG officials who negotiated with the Sangheili to be traitors to the human race.

The idea of treason is present within Sangheili culture. It is punishable by death.

An analogous concept to treason within the Covenant is that of heresy.

• Chen Bax - Scientist and ONI civilian contractor. Late in the Human-Covenant War he became disillusioned with ONI and the UNSC, believing that they no longer represented humanity's best interests. Consequently he stole classified technology, but before he could be apprehended he was believed to have been killed during the Fall of Reach. However, ONI later discovered that this was not the case and tasked Linda-058 with eliminating him. He was found to be living on Sephune III along with other survivors of the Fall of Reach. He died while activating the self-destruct of the UNSC Promise of Dawn in order to protect the other survivors from Jul 'Mdama's Covenant.
• Daniel Clayton - Captain in the UNSC Navy and illegitimate son of James Cutter. Following the revelation that Lord Hood had been supporting his career and therefore feeling he had accomplished nothing for himself, Clayton defected to the New Colonial Alliance in 2558. Subsequently, he was involved in an attempt on Hood's life. Following the failure of this attempt, Clayton next tried to ambush and destroy the UNSC Infinity. This attempt too failed, and Clayton was captured and incarcerated.
