*536The opinion of the court was delivered by
Magie, J.Several of the reasons filed by prosecutors attack the validity of the proceedings brought before us by this writ, upon the’ ground that the “Act providing for the formation and establishment of wards in cities of the first class in this state,” passed May 16th, 1894, was obnoxious to constitutional prohibitions or had been repealed before these proceedings were taken.
Objections precisely similar have heretofore been considered by this court and declared to be without substance. McLaughlin v. Newark, ante p. 298. Therefore, those now made cannot prevail.
Of the remaining reasons filed by prosecutors, only one need be considered. That questions the validity of the acts of the commissioners in respect to wards, upon the ground that they, “ in dividing Jersey City into wards, have not had regard to equality of population.”
The above-mentioned act of May 16th, 1894, gives authority to a mayor of any city of the first class to appoint five commissioners, whose duty shall be, after having taken a prescribed oath, to divide such city into wards. It expressly enacts that “all such wards shall be formed of contiguous territory, and in dividing the same the said commissioners shall have regard to equality of population.”
The act further provides that the action of the commissioners is to be evidenced by maps defining the lines of wards, to be made and filed by the commissioners in the office of the city clerk, with a description of such lines, all to be attested and certified by the commissioners and to there remain of record.
The reason under consideration does not question the validity of the attestations aud certificates of the commissioners, on the ground that they fail to show that the division of the city1- into wards had been made in accordance with these requirements of the act. As these commissioners were empowered to do certain acts in a prescribed mode, the well-settled rule, which requires such persons, when their acts are only *537to be authenticated by their certificates, to show on the face thereof that they have strictly pursued their authority, may be applicable. The rule is applied to the condemnation of lands (Vanwickle v. Railroad Company, 2 Gr. 162), to municipal acts and assessments (State v. Jersey City, 1 Dutcher 309; State v. Jersey City, 2 Id. 444; Wilkinson v. Trenton, 7 Vroom 499), to tax adjudications (State v. Warford, 3 Id. 207) and to the orders and returns in laying out roads (State v. Van Gieson, 3 Gr. 339; State v. Bergen, 1 Zab. 342), and it would not be easy to discover a reason for not applying a similar rule to the case in hand, where the certificates of the commissioners furnish the only record of their acts.
If this rule is applicable, it is obvious that the attestations and certificates of the commissioners, appearing in the return, are defective, and, upon proper objection, ought to be vacated on that ground, for they are entirely silent as to the principle on which the division into wards was made, and do not show that, in making such division, the commissioners had any regard to equality of population.
But, as before stated, this reason seems not to present this objection, but rather to assert that the commissioners, in making such division into wards, did not, in fact, have regard to equality of pópulation as required by the act. Defendants insist that it thus presents a question of fact, and, as prosecutors have taken no affidavits to establish the alleged breach of duty on the part of the commissioners, that it cannot prevail.
But proof by affidavits is unnecessary, if the fact is otherwise established.
In the minutes of the commissioners, kept by their secretary and returned in obedience to the command of this certiorari, it appears that, at a meeting on July 26th, 1894, they unanimously adopted the following resolution:
“Resolved, That for the purpose of conforming to the aldermanic requirements, the ward lines be drawn so as to form twelve wards as compactly and of as nearly an average total vote as possible.”
*538No other action indicative of a change in the purpose declared in that resolution appears, and the division was made into twelve wards.
It thus appears that the ward lines were drawn so as to give to each ward as nearly as possible an equal average vote. This may have been a commendable purpose, inasmuch as it tended to produce equality of representation. Rut that was not the duty laid upon the commissioners by the act of the legislature. They were required to make their division with regard to equality of population, and that duty was not performed by making the division with regard to equality of votes.
It may be true, as argued, that the average vote of a locality bears some relation to its population, but that relation is not so certain or accurately known as to justify reliance upon it in determining the population of the locality.
The result is that the certificates and attestations appearing in this return must be vacated and set aside, with costs.
