delivered the opinion of the court.
In the case of Bradley vs. The Commissioners of Powel county, heard and determined by this court, at Knoxville, in the year 1841, and reported in 2 Hum., 428, it was held, that commissioners, appointed to organize a county, under an act of the legislature establishing it, should be enjoined from the performance of that duty, where the county had been established by the legislature, in violation of the 4th sec. of 10th art. of the amended constitution of the state, which provides that “new counties may be established by the legislature, to consist of not less than three hundred and fifty square miles, and which shall contain a population of four hundred and fifty qualified voters; no line of which county shall approach the court-house of any old county, from which it may be taken, nearer than twelve miles.”
In that case it clearly appeared, that the area contained within the lines of the county, as defined by the act establishing it, was not equal to three hundred and fifty square
Upon a review of this case, we are satisfied of the correctness of its doctrine and re-affirm it. The act of the legislature having been passed in violation of the constitution, had no validity, and of course conferred no power upon the commissioners appointed by it, who were, therefore, proceeding in violation of law, to mark and
But in the case now under consideration, we are asked to go a step further and abolish a county after it has been organized and put into operation, under an act of the legislature establishing it. This is presenting the question in a very different aspect indeed, and we know of no principle of Chancery jurisprudence, upon which the jurisdiction thus invoked can be exercised. The prohibition of an act, and the undoing of it after it has been performed are very different things, and the jurisdiction of a court of Chancery can be maintained in many instances for the one, while the person agrieved is left solely to his remedy at law for the other: and such, we think, most clearly to be the case now under consideration: as long as the organization of the county is in fieri, the court has power over the commissioners appointed by the invalid act establishing it, and may prohibit them from the exercise of the authority illegally imposed upon them by it; but the moment the power is executed, and the county organized in pursuance of the statute, that moment the connexion of the commissioners with the transaction ceases; they become, if the expression be legitimate, functi officio;
As to the question made upon the boundary lines of this county; it being alleged, that they are run within a distance of other county seats, prohibited by the constitution, or twelve miles; it is to be observed, that this prohibition is made in favor of the counties, and a violation of it, violates rights secured by the constitution to them, which cannot be permitted, as it would be an unconstitutional divestment of a vested right; the consequence of which is, the adjoining counties are not bound by the running of these lines/ if they trench upon the limits thus secured to them, that is, the twelve miles from the seat of justice; ■ but they may force these lilies back to the required distance if they see proper so to do..
Then upon the whole view of this case, .we reverse the decree of the Chancellor, and dismiss the complainant’s bill with costs.
