The latter arrangement became of great importance also, in so far that thereby for the first time alongside of the two standing supreme magistrates were placed two assistants, whom each supreme magistrate nominated at his entrance on office, and who in due course also went out with him on his leaving it--whose position thus, like the supreme magistracy itself, was organized according to the principles of a standing office, of a collegiate form, and of an annual tenure.

This was not indeed as yet the inferior magistracy itself, at least not in the sense which the republic associated with the magisterial position, inasmuch as the commissioners did not emanate from the choice of the community; but it doubtless became the starting-point for the institution of subordinate magistrates, which was afterwards developed in so manifold ways.
In a similar way the decision in civil procedure was withdrawn from the supreme magistracy, inasmuch as the right of the king to transfer an individual process for decision to a deputy was converted into the duty of the consul, after settling the legitimate title of the party and the object of the suit, to refer the disposal of it to a private man to be selected by him and furnished by him with instructions.
In like manner there was left to the consuls the important administration of the state-treasure and of the state-archives; nevertheless probably at once, or at least very early, there were associated with them standing assistants in that duty, namely, those quaestors who, doubtless, had in exercising this function absolutely to obey them, but without whose previous knowledge and co-operation the consuls could not act.
Where on the other hand such directions were not in existence, the president of the community in the capital had personally to intervene; as indeed, for example, at the introductory steps of a process he could not under any circumstances let himself be represented by deputy.
This double restriction of the consular right of delegation subsisted for the government of the city, and primarily for the administration of justice and of the state-chest.

As commander-in-chief, on the other hand, the consul retained the right of handing over all or any of the duties devolving on him.

This diversity in the treatment of civil and military delegation explains why in the government of the Roman community proper no delegated magisterial authority (-pro magistrate-) was possible, nor were purely urban magistrates ever represented by non-magistrates; and why, on the other hand, military deputies (-pro consuls-, -pro praetore-, -pro quaestore-) were excluded from all action within the community proper.
Nominating a Successor The right of nominating a successor had not been possessed by the king, but only by the interrex.( 7) The consul was in this respect placed on a like footing with the latter; nevertheless, in the event of his not having exercised the power, the interrex stepped in as before, and the necessary continuity of the office subsisted still undiminished under the republican government.

The right of nomination, however, was materially restricted in favour of the burgesses, as the consul was bound to procure the assent of the burgesses for the successors designated by him, and, in the sequel, to nominate only those whom the community designated to him.
