The domain-land thus resumed was to be broken up into lots of 30 jugera; and these were to be distributed partly to burgesses, partly to Italian allies, not as their own free property, but as inalienable heritable leaseholds, whose holders bound themselves to use the land for agriculture and to pay a moderate rent to the state-chest.

A -collegium- of three men, who were regarded as ordinary and standing magistrates of the state and were annually elected by the assembly of the people, was entrusted with the work of resumption and distribution; to which was afterwards added the important and difficult function of legally settling what was domain-land and what was private property.

The distribution was accordingly designed to go on for an indefinite period until the Italian domains which were very extensive and difficult of adjustment should be regulated.

The new features in the Sempronian agrarian law, as compared with the Licinio-Sextian, were, first, the clause in favour of the hereditary possessors; secondly, the leasehold and inalienable tenure proposed for the new allotments; thirdly and especially, the regulated and permanent executive, the want of which under the older law had been the chief reason why it had remained without lasting practical application.
War was thus declared against the great landholders, who now, as three centuries ago, found substantially their organ in the senate; and once more, after a long interval, a single magistrate stood forth in earnest opposition to the aristocratic government.

It took up the conflict in the mode--sanctioned by use and wont for such cases--of paralyzing the excesses of the magistrates by means of the magistracy itself.( 31) A colleague of Gracchus, Marcus Octavius, a resolute man who was seriously persuaded of the objectionable character of the proposed domain law, interposed his veto when it was about to be put to the vote; a step, the constitutional effect of which was to set aside the proposal.
