decree existing obligations towards the gods or towards foreign states or organic institutions of the community. But still it was a matter of the greatest importance that--to take an example--when the Roman king had proposed a declaration of war and the burgesses had converted it into a decree, and when the satisfaction which the foreign community seemed bound to furnish had been demanded in vain, the Roman envoy invoked the gods as witnesses of the wrong and concluded with the words, "But on these matters we shall consult the elders at home how we may obtain our rights;" it was only when the council of elders had declared its consent, that the war now decreed by the burgesses and approved by the senate was formally declared. Certainly it was neither the design nor the effect of this rule to occasion a constant interference of the senate with the resolutions of the burgesses, and by such guardianship to divest them of their sovereign power; but, as in the event of a vacancy in the supreme office the senate secured the continuance of the constitution, we find it here also as the shield of legal order in opposition even to the supreme power--the community. The Senate As State-Council With this arrangement was probably connected the apparently very ancient usage, in virtue of which the king previously submitted to the senate the proposals that were to be brought before the burgesses, and caused all its members one after another to give their opinion on the subject. As the senate had the right of cancelling the resolution adopted, it was natural for the king to assure himself beforehand that no opposition was to be apprehended from that quarter; as indeed in general, on the one hand, it was in accordance with Roman habits not to decide matters of importance without having taken counsel with other men, and on the other hand the senate was called, in virtue of its very composition, to act as a state-council to the ruler of the community. It was from this usage of giving counsel, far more than from the prerogatives which we have previously described, that the subsequent extensive powers of the senate were developed; but it was in its origin insignificant and really amounted only to the prerogative of the senators to answer, when they were asked a question. It may have been usual to ask the previous opinion of the senate in affairs of importance which were neither judicial nor military, as, for instance--apart from the proposals to be submitted to the assembly of the people--in the imposition of task-works and taxes, in the summoning of the burgesses to war-service, and in the disposal of the conquered territory; but such a previous consultation, though usual, was not legally necessary. The king convoked the senate when he pleased, and laid before it his questions; no senator might declare his opinion unasked, still less might the senate meet without being summoned, except in the single case of its meeting on occasion
