The lex Caecilia Didia was a law put into effect by the consuls Q. Caecilius Metellus Nepos and Titus Didius in the year 98 BC.[1] This law had two provisions. The first was a minimum period between proposing a Roman law and voting on it, and the second was a ban of miscellaneous provisions in a single Roman law. This law was reinforced by the lex Junia Licinia in 62 BC, an umbrella law introduced by Lucius Licinius Murena and Decimus Junius Silanus.[2]
