Rogatio

In Roman constitutional law, rogatio is the term (from Latin rogo, "ask, place a question before") for a legislative bill placed before an Assembly of the People in ancient Rome. The rogatio procedure underscores the fact that the Roman senate could issue decrees, but was not a legislative or parliamentarian body. Only the People could pass legislation.

A magistrate with the right to summon the assembly could propose a bill (rogatio legis); the proposed laws themselves were leges rogatae. A bill's proposer was its lator; a supporter was an auctor. Discussions in the senate would contribute to the drafting of a bill, which would be published (promulgare rogationem, that is, promulgatio) three weeks or more before it was formally submitted to the assembly. During this period, citizens could discuss the bill and propose changes, or more rarely ask for its withdrawal, at informal sessions (contiones). After the bill had been brought before the assembly for the vote, it could no longer be modified.

The legislator who introduced the bill asked Velitis iubeatis, Quirites? ("Citizens, are you going to approve and order?") and the people responded yea or nay without discussion. If a bill was withdrawn after the rogatio but before the vote was taken, it was usually because a tribune threatened to use his veto power against it, or less frequently because it proved unpopular among the plebs. If a bill was passed (rogatio lata est), it became a law (lex) after the presiding magistrate made a formal announcement (renuntiatio) of the assembly's decision.

In the Early Republic, the senate had to approve the constitutionality of a law before it was enacted; after the passage of the Lex Publilia Philonis in 339 BC, which required that at least one of the two censores be a plebeian, this approval (patrum auctoritas) was required before the bill was put to a vote in the assembly. With controversial popularist measures, however, the senate was sometimes bypassed. If a bill was proposed for the purpose of declaring war, it had to be brought before the Centuriate Assembly.
