delivered the opinion of the court.
The right of the district court to order a sale of mining property under the statute, where it cannot be partitioned without great prejudice to the owners, in a cause commenced before the adoption of the amendment of 1893, is the single question presented by this record. It is admitted that if the proviso of April 8,1893, which in terms prohibits the sale of mining property in a partition proceeding, applies to this case, then the judgment of the district court is erroneous, and must be reversed.
Appellants claim that the act in question affects merely the remedy, and is, therefore, not obnoxious to the constitutional provision. The action having been commenced prior to the passage of the act, the district court held that the amendment did not govern, but that the cause of action was protected by the provision of the bill of rights inhibiting retrospective legislation.
Retrospective legislation has always been condemned by the courts as unfair and prejudicial, so that, in the absence of any constitutional restriction, the courts have universally construed all legislation as prospective only in its operation, unless by the plain and positive language of the act an intent was manifest to make its provisions retrospective. As this ruling of the courts was founded upon the plainest principles of natural justice, it has been extended and given a place in the constitutions of several of the states, including Colorado.
*148These constitutional provisions, although couched in somewhat different phraseology, aim at the same evils, and are substantially alike. They have heen before the courts for consideration in numerous instances, and, as a result of the decisions, the rule has become fixed, which, on the one hand, denies the right of the legislature to create a new ground for the support of an existing cause of action or to take away any legal defense to such action, while, on the other, any ground upon which an action is founded cannot be annulled or any new bar thereto created. Denver, etc., Ry. Co. v. Woodward, 4 Colo. 162; French v. Deane, 19 Colo. 504; Rich v. Flanders, 39 N. H. 347; Kent v. Gray, 53 N. H. 576; De Cordova v. City of Galveston, 4 Texas, 469.
Mining property, from its very nature, is not, as a rule, susceptible of partition. The ores are unevenly distributed, while the values are purely conjectural until tested by extended development and careful tests, which earn only be obtained as the result of a vast expenditure of money and time; so that it is known in advance of bringing suit for partition that the only feasible relief that can be awarded is a decree for the sale of the property. Take away this relief, and no cause of action can be maintained.
This is not a case where a substantial remedy has been left under the statute, but where the nature and extent of such remedy has been abridged; for, if we give the statute the construction contended for by appellants, no relief whatsoever can be had; but the action must be dismissed, although a perfect right of action existed at the time the proceeding was instituted. Of such a statute, in Kent v. Gray, 53 N. H. 579, it is said :
“A statute abolishing the action of assumpsit, and substituting for it the action of debt, might be applied, without injustice, to existing causes of action not in suit; but it could not be constitutionally applied to oppress a plaintiff in a pending suit in assumpsit. Having incurred expense in bringing a proper suit, and pursuing a remedy provided by law, it would be unjust to turn him out of court, render a *149judgment against him for the defendant’s costs, and leave him to another remedy, in the pursuit of which he might again be defeated in the same manner by another statute. In one sense, such legislation would affect the remedy only; but, in the constitutional sense, it would be retrospective, injurious, oppressive, and unjust, and, therefore, unconstitutional ; and it is not apparent how the constitutional sense in such a case would be elucidated by a distinction between a right and a remedy. The injustice would be manifest; and the test given by the bill of rights is, not the distinction between right and remedy, but the distinction between right and wrong. On other subjects, the ground of judicial decision is not ordinarily understood to be so broad as the general principles of justice; but, on this subject of retrospective legislation, those principles are the constitutional ground amply supported by the authorities.”
It is idle to attempt to draw a distinction in law between a right which does not exist, and one that cannot be enforced. Right and remedy are reciprocal. Take away a plaintiff’s remedy, and you destroy the value of his right. A constitutional inhibition goes to the substance of the evil, not the shadow. This was evidently the view taken by the district court, and its judgment must be upheld upon constitutional grounds, without reference to the saving act of 1893. This statute appears to have been largely copied from the Revised Statutes of the United States. Originally, it applied to criminal cases only; but, as adopted by our legislature, it embraces civil as well as criminal matters. See United States v. Reisinger, 128 U. S. 398.
As the judgment of the district court must be upheld upon constitutional grounds, the effect of this act will not be determined.
Affirmed.
