This action was brought July 19, 1889. The judgment appealed from restrains the defendants from maintaining an elevated railway structure on or in front of plaintiff’s premises, known as No. 15-J- Division street in the city of New York. The injunction is nqt to be operative if the defendants shall within one month elect to pay plaintiff the sum of $1,500, as and for the permanent damages to the fee of the premises sustained by him in consequence of the appropriation by the defendants of the use of the street for such a purpose. Upon payment, or tender of such sum the plaintiff is required to execute a conveyance of the property found by the decision to have been taken by the defendants, and in case of failure to execute such conveyance it is, in substance, provided that the judgment of injunction shall have no force or effect. Damages to the amount of $500 are also awarded for the injury to the property during the time intervening between June 10, 1887, and-March 20, 1890.
The rightfulness of this judgment is not questioned exceptjupon a single ground. It was proven by the plaintiff upon the trial, and it has been found by the trial court, that after issue was joined and on March 20, 1890, the plaintiff conveyed the premises to one Rosenbaum, for the consideration of $8,800. It is, for this reason, contended that plaintiff was not, at the time of the trial, entitled to any preventive relief with respect to these premises, and, in the absence of the right to such relief, that the court could not retain jurisdiction of the action for the purpose of awarding damages for past injuries. It is undoubtedly true that the substantive cause of action in all such cases is the right to a prevention of the continuance of the trespass upon plaintiff’s property by the defendants, but when this right is established the equitable jurisdiction of the court is complete, and it can award the injured party full compensation for all the damages sustained by the wrongful act sought to be enjoined, subject to the statutory limitations of time.
It is equally true that if there is no such right to a preventive remedy, the matter of damages for past trespasses cannot be the subject of inquiry in a court of equity. Relief must be sought in another forum. In this connection, it is to be observed that the defendants do not claim that the right to this - kind of a remedy is extinguished by a transfer during the pendency of the action. Its existence is admitted, but it is asserted that it has been transferred by the plaintiff’s own act to his grantee, and that the latter alone can prosecute the action. It would seem that in such a case § 756 of the Code of Civil Procedure would be a suffi*77cient answer to such an objection. That section provides that in case of a transfer of interest, the action may be continued by the original party, unless the court directs the person to whom the interest is transferred to be substituted in the action or joined with, the original party, as the case requires. The action proceeds in the same manner as if the conveyance of the property, which is the .subject of the controversy, had not been made, unless the court directs the grantee to be made a party. The question cannot properly be presented for the first time upon the trial of the action, but must be brought to the attention of the court either by motion or by a supplemental pleading. If the defendant has not had .the means of knowing that the plaintiff has parted with his title to the subject matter of the action until the fact is disclosed upon the trial, and he desires to have the new party in interest substituted for or joined with the original plaintiff, he can move to have .the trial arrested until the necessary steps can be taken for that purpose, and the trial court can suspend the proceedings, if, in the exercise of a sound discretion, it is satisfied that the adoption •of such a course is necessary for the protection of the defendant. It is not seen how, ordinarily, the defendant is prejudiced by a transfer of the plaintiff’s interest pendente lite, unless there is some •question of the solvency of the parties involved. A judgment recovered against the original party would as effectually conclude his assignee after suit brought upon all the issues litigated as if the latter had been substituted in place of his assignor. The .statute makes no distinction in this respect between actions at law and in equity, provided the cause of action is assignable. •Story’s Equity Pleadings, § 156.
This view does not militate against the rule which authorizes courts of equity, where they have once obtained jurisdiction of .a cause, to administer all the relief which the nature of the case and the facts require, and to bring such relief down to the •close of the litigation between the parties. The subject of the controversy remains unchanged; which is the unlawful appropriation of certain rights, or easements, which are appurtenant or incident to the premises designated in the complaint, and if the decree rendered concludes the owner of the property, wherever he may be, it matters not that the title has shifted during the progress of the action.
But in the present case the plaintiff has not parted with his title to the cause of action, or to the entire property to which it relates. His deed to Rosenbaum contains the following important reservations: “Reserving to the vendor all damages to said property caused or to be caused by the present, past or future maintenance and- operation of. the elevated railway on Division, street as now constructed, and all the fee and easement in Division street now or heretofore or hereafter occupied and invaded by the said elevated railway structure, when maintained and operated as aforesaid, and the conveyance is made subject to the said reservation to the said party of the first part, his heirs, •executors and administrators.”
He has thus retained all the title which he ever had to the *78rights and easements appropriated by the defendants and to the fee of one-half of the street in width in front of No. 15£ Division street. This street was laid out in 1765, under articles of agreement between Henry Rutgers and James DeLancey, who owned the lands which it traverses, by the terms of which it was mutually covenanted that it should be laid out on the division line between their respective farms, and each granted to the other a fee interest in that half of the street immediately abutting upon the grantee’s property, subject to the right of t.he public to use the same as a highway; and each conveyed to the other an easement of light, air ana access in the remainder of the street. The decision of this court in Henderson v. N. Y. Central R. R. Co., 78 N. Y., 423, thus becomes directly applicable.
In that case the plaintiff, when he brought-the action, was the owner of some of the abutting lots and also of the fee of the street, subject to the public easement therein for the purposes of a highway. Before the action was brought the plaintiff had sold some of the lots and before the. last trial of the action had sold and conveyed the remaining lots, reserving, however, the fee of the street and the damages to the adjacent property, both past and prospective; and it was held that his right to the equitable interierence of the court for his protection against the encroachments of the defendants was not thereby affected, and the court decreed a perpetual'injunction, unless the defendants paid the amount found by the referee to be a fair compensation for the additional burden imposed upon his property. It is true, there is not a separate finding in this case, as there was there, as to the value of the fee of the street or its depreciation in consequence of its occupation by the defendants. But it is not seen how the application of the principle is in any wise affected by this omission. It has been found that the existence and use of the defendants’ structure and its threatened. continued use has permanently damaged the fee value of the entire premises to the amount of at least fifteen hundred dollars. There was no request to find, separately, the amount of permanent damage to the fee of the street and to the property conveyed by the plaintiff.
• They are so connected-that a separate finding as to each might be difficult, if not impracticable. - As the right to the damages to-both pieces of property was still in the plaintiff, such a finding was unnecessary. So long as the ownership of the fee of the street and of the damages to the adjacent property remained in the same person, equity would -not permit the defendants, to acquire a right to maintain its structure in the street without paying the damages to the adjacent property which the erection and maintenance of such structure have inflicted upon it.
This view is in harmony with the well settled rules of equitable jurisprudénce. No principle has been more frequently asserted, or is so well established, as that when a court of equity has jurisdiction over a cause for any purpose, it may retain the cause for all purposes and proceed to a final determination of all.the matters at issue. To such an extent has the doctrine been carried that it has been declared that if the controversy contains any equitable *79feature, or requires any purely equitable relief belonging to the exclusive jurisdiction of equity, or pertaining to the concurrent jurisdiction of equity and law, and a court of equity thus acquires a partial cognizance of the action, it may go on to a complete adjudication and establish purely legal rights and grant legal remedies which would otherwise be beyond the scope of its authority. Pomeroy’s Eq. Juris., §§ Í81, 231, 242. So long as one of the grounds of equitable interference in this class of cases is the avoidance of a multiplicity of suits, this rule must prevail. The plaintiff being entitled to a decree restraining the defendants from the unlawful use of .the street in which he still has an interest, it was the duty of the court to award him all the damages sustained in consequence of such unlawful use. As to the permanent damages for the injury to the fee, the defendants are not compelled by this judgment to pay them. They have been ascertained and payment of them provided for as a favor to the defendants, and as a condition upon which they may be relieved from the disastrous consequences to their business which must result from the maintenance of the perpetual injunction, to which in strict equity the plaintiff .is entitled. The defendants are not harmed, but favored by such a disposition of the cause. Further litigation is avoided and a perfect right acquired to maintain in the street in front of these premises what has hitherto been an illegal and unauthorized structure. The grantee of the plaintiff has no interest in the subject of this controversy.. He has taken his conveyance with a reservation to the plaintiff of the fee of the street and the permanent damages to the adjoining property. Presumably, to the extent of the value of the rights thus reserved, the cost of the property to him has been proportionately diminished. He is estopped by the reservation in his deed, which is to be given the same effect as a direct grant, from asserting any title to any part of this cause of action, or to the rights which the defendants will acquire under the judgment, which puts them in privity of title with the plaintiff.
We have not considered, and, in view of the peculiar features of this case, we deem it unnecessary to consider or determine the abstract question, whether the owner of real property injuriously affected by the maintenance of an unlawful structure in the street upon which his property abuts can, either before or after suit brought, convey the entire premises and reserve to himself the right to maintain an action in equity to restrain the continuance of such structure, or for the recovery of the permanent damages to the property by reason of its maintenance. Such question must be reserved until it arises in concrete form. In the present case the grantor has retained title to a part of the fee of the premises, and unquestionably sufficient to preserve intact the jurisdiction of a court of equity.
The judgment must be affirmed, with costs.
All concur.
