1 It is, however, to be observed that the Edict of the aedile forbids dogs, boars, bears, or lions to be kept near where there is a public road, and directs that if any injury be caused to a free man through disobedience of this provision, the owner of the beast shall be condemned to pay such sum as to the judge shall seem fair and equitable: in case of any other injury the penalty is fixed at double damages. Besides this aedilician action, that on pauperies may also be sometimes brought against the same defendant; for when two or more actions, especially penal ones, may be brought on one and the same ground, the bringing of one does not debar the plaintiff from subsequently bringing the other.
TITLE X. OF PERSONS THROUGH WHOM WE CAN BRING AN ACTION
We must now remark that a man may sue either for himself, or for another as attorney, guardian, or curator: whereas formerly one man could not sue for another except in public suits, as an assertor of freedom, and in certain actions relating to guardianship. The lex Hostilia subsequently permitted the bringing of an action of theft on behalf of persons who were in the hands of an enemy, or absent on State employment, and their pupils. It was, however, found extremely inconvenient to be unable to either bring or defend an action on behalf of another, and accordingly men began to employ attorneys for this purpose; for people are often hindered by illhealth, age, unavoidable absence, and many other causes from attending to their own business.
1 For the appointment of an attorney no set form of words is necessary, nor need it be made in the presence of the other party, who indeed usually knows nothing about it; for in law any one is your attorney whom you allow to bring or defend an action on your behalf.
2 The modes of appointing guardians and curators have been explained in the first Book.
TITLE XI. OF SECURITY
The old system of taking security from litigants differed from that which has more recently come into use.
Formerly the defendant in a real action was obliged to give security, so that if judgement went against him, and he neither gave up the property which was in question, nor paid the damages assessed, the plaintiff might be able to sue either him or his sureties: and this is called security for satisfaction of judgement, because the plaintiff stipulates for payment to himself of the sum at which the damages are assessed. And there was all the more reason for compelling the defendant in a real action to give security if he was merely the representative of another. From the plaintiff in a real action no security was required if it was on his own account that he sued, but if he was merely an attorney, he was required to give security for the ratification of his proceedings by his principal, owing to the possibility of the latter's subsequently suing in person on the same claim. Guardians and curators were required by the Edict to give the same security as attorneys; but when they appeared as plaintiffs they were sometimes excused.
