The Chamber of Peers was appointed by the King, and could consist of both hereditary aristocrats and life peers ennobled in recognition of public service (Article 27). The number of peers was unlimited, meaning that the King could, at any time, add to their number. In addition to its legislative and deliberative role, the Chamber of Peers also acted as a special court for the trial of impeachments (Article 55) and for cases of "high treason and attacks against the security of the state" (Article 33). During the Napoleonic Hundred Days period, the Charter was suspended, only to come back into force after Napoleon’s abdication in 1815. All 29 peers appointed in 1814 were removed from power following it for allying with him. New peers were appointed in August of the same year, with most of the previously removed getting reinstated in the following years, albeit at a lower rank.
