Inhabitants of China vs. Southwick & al., 11 Me. 341

Mellen C. J. The singlo question reserved is, whether Moor and Greenlow were properly admitted as witnesses on the part of the defendants. Were they interested in the event of this suit? In 2 Stark. Ev. 744, the law on this subject is laid down in these words : “ The interest to disqualify” a witness “ must be some legal, certain and immediate interest, however minute, in the result of the cause, or in the record, as an instrument of evidence, acquired without fraud. ” In Bent v. Baker, 3 T. Rep. 27, and in Smith v. Prague, 7 T.

Rep. 60, the rule is laid down in these words : “ That no objection could be made to the competency of a witness upon the ground of interest, unless he were directly interested in the event of the suit, or could avail himself of the verdict, so as to give it in evidence on any future occasion, in support of his own interest.” The passage cited by the plantiffs’ counsel from 2 Stark. 746, is in these words: “ a party has such a direct and immediate interest in the event of a cause as will disqualify him, wben the necessary consequence of a verdict will be to better his situation, by either securing an advantage or repelling a loss; he must be either a gainer or loser by the event. ” — See also Schillinger v.

McCann, 6 Greenl. 364, and the cases there cited by the counsel and the Court. The plaintiffs’ counsel frankly and very properly admits that the verdict in this cause can never be given in evidence in favor or against either of the witnesses in any action they may bring ; but it is said that they are interested in the event of this suit. The dam which the defendants erected and which raised the water in the pond, was to “ keep up in the pond a reservoir of water for the common benefit” of the owners of the successive mills on the stream leading from the pond.

It could not be a common benefit, according to the facts as stated ; because those mills are not owned in common, but in severalty. The witnesses had an interest in some of the mills only,. In the case of the town of Calais v.

Dyer, 7 Greenl. 55, it was decided that where the defendant’s mill-dam had raised the water so as to overflow a town road and damage it, the town could not maintain a complaint under our statute, ch. 45, against Dyer, because the town did not own the laud ; but that there seemed to be no good reason why a special action on the case could not be maintained against him for damages to reimburse the expenses incurred in repairing the road ; and that perhaps the dam might bo indicted as a nuisance to the public, though as to the owners of lands flowed, the dam was lawfully erected and maintained in virtue of said act.

It is said, that if it may be indicted as a nuisance, it may also be abated, and such an abatement would essentially injure all the mills, and therefore the witnesses were interested to testify so as to defeat the action, for the preservation and continuance of the dam. Is not this plainly a non sequitur'l Have not the defendants a legal right to maintain the dam, if they should guard the road so that it will not be overflowed and injured ? is it certain that they will not ?

If they should not so guard it, is it certain that they will be indicted for a nuisance, and that the dam will be removed and abated as such ? Is such a remote probability of an event, over which the witnesses can have no control whatever, any more than an interest which goes to the credit of the witnesses, and not to their competency ? Is it, in the language of Starkie, “ a legal, certain and immediate interest” in the witness ? But there is another answer to the objection. The interest must be one in the event of this suit. This action never can, and never could have any effect upon the dam.

If the plaintiffs had recovered damages against the defendants, no execution on the judgment could have any legal effect as to the continuance or abatement of the dam. In this action, therefore, the witnesses could not have any legal interest; they could not gain or lose any thing in any event of it; they were therefore properly admitted, even if they could not be competent witnesses for the defendants in the trial of an indictment against them for a nuisance in the erection of said dam.

The cases which the counsel for the plaintiffs has cited from Massachusetts Reports and some other books, as to the inadmissibility of persons as witnesses in an action relating to certain alleged customs, and who are interested in the existence of the custom, are not applicable in a case like the present. The principle, excluding such persons, seems to be of a peculiar nature, and rather as an exception from the general rules of evidence. Besides, in those cases, the interest in question, from its nature, must be a common one; and when once established by law, belongs to the local community where it exists.

But in the case before us, the witnesses did not erect the dam, nor does it appear that they own any part of it, either in common or in severalty. For the reasons assigned, the Court is of opinion that there must be Judgment on the verdict.
