The Roman assemblies were the Comitia Calata, the Comitia Curiata, the Comitia Centuriata, and the Comitia Tributa. They possessed ultimate
legislative and
judicial powers in the
Roman Republic and were also responsible for the election of
magistrates.Unlike
legislatures in countries such as the
United States, the Roman assemblies were seen to embody the People of Rome, not merely being an elected body of representatives, and thus possessed ultimate
legislative powers, including the ability to pass
ex post facto laws and
bills of attainder. They could also act as a court of appeal for death. They were also not
deliberative assemblies: normal citizens neither debated nor proposed legislation (only
magistrates could propose legislation). The assemblies also possessed
judicial powers, some of which were transferred to permanent courts later in the Republic. The absence of modern
separation of powers did not mean that checks and balances were absent from Roman government (they were in fact remarkably elaborate).
