As we interpret the record, the evidence was not excluded because of any lack of the qualifications of the witnesses, or as an exercise of discretion, but because of the lack in probative value as a matter of law. This was error. It cannot be said as a matter of law in advance of the submission of the proffered evidence, that the adaptability of the plaintiff’s property for development and use in conjunction with the properties of others adjacent thereto, above or below, may not have been so patent, that the possibility of the combination of the properties essential to such development may not have been so promising, and that the demand for the plaintiff’s property for the purpose of such a combination may not have been so great, thgtt the judgment of prospective purchasers would not have been affected thereby, and the market price of her said property, therefore, enhanced. The exclusion of all evidence of the alleged enhanced market value of plaintiff’s property by reason of its adaptability for development in conjunction either with the defendant’s property, or with that of others, precluded the plaintiff from her rightful opportunity to show such value if she could. Whether the evidence would have sustained her offer with respect to any given combination is quite another question, and one which was not reached.
The foregoing conclusion makes it unnecessary to consider the plaintiff’s further exceptions. But as there must be a new trial some of the general principles involved, as disclosed by the record and arguments, have been considered.
The defendant assumes in argument that one of the plaintiff’s contentions is that she is entitled to have her undeveloped water power appraised at what it is worth to the defendant, computed upon the proportion which the fall upon her land bears to the whole falls involved in the defendant’s development. See plaintiff’s requests Nos. 2 and 6. Although the plaintiff does not expressly concede such to be her claim the position of her counsel at the trial and in argument affords ground for the defendant’s assumption. Such a contention has therefore been considered.
When the property has a special utility to the taker and to others who could have used it for the purpose for which it is sought, and that utility is such that it would probably have affected the judgment of one desiring to purchase, such utility may be shown.
