THOMPSON, Circuit Justice.
The defendant recovered, in an action of ejectment, the premises on which the improvements now in question had been made, and the present action is brought under the provisions of a statute of this state to recover the value of such improvements. The plaintiffs were bona fide purchasers,, supposing themselves to have a good title to the premises. The improvements were made prior *297to the act under which the present suit is brought, which bears date on the 15th November, 1820. This act declares that it shall not extend to cases accruing after the passage of this act, and is, therefore, in terms retrospective, and presents the question directly whether this court has authority to declare such law void, and this is the only question involved in the case. By the common law, when the owner recovers his land in an action of ejectment, he is entitled to the possession without paying for any improvements which may have been made upon his land. Such improvements are considered as annexed to the freehold, and to have been made at the peril of the possessor. The civil law, however, in this respect varies from the common law, and, according to the rule which there prevails, a bona fide possessor is entitled to be reimbursed, by way of indemnity, the expenses of beneficial improvements. This would seem to be founded on principles of equity, so far as the actual value of the property is increased by the labor of another. The common law, acting under the maxim of caveat emptor, considered this as too loose a rule, and opening a door calculated to give encouragement to intrusions upon land, without due and proper inquiry into the title. It has, however, been pretty strongly intimated by English chancellors, that when a party is obliged to resort to a court of equity for the recovery of the rents and profits of his land, a bona fide possessor would be allowed to deduct the amount of his actual expenses for beneficial improvements. [Dormer v. Fortescue,] 3 Atk. 134. But this rule, if adopted, ought not to be applied to any case when there was not the most satisfactory evidence that the possession was taken in good faith, and under a full belief that the title had been acquired from the rightful owner.
The law now in question is not repugnant to any express provision in the constitutions of the United States or of the state of Vermont. The only article in the constitution of the United States that can possibly have any bearinupon the question, is that which declares that no state shall pass any ex post facto law, or law impairing the obligation of contracts. Article 1, § 10. This is not an ex post facto law, acording to the legal understanding of laws of this description. They relate only to criminal cases and venal statutes. Nor does it impair the obligation of any contract. There is no subsisting contract between these parties which could be impaired. There is no conflict between the constitution of the state of Vermont and this law. The only provision at all looking to the question is that which declares that the legislative and judicial and executive departments shall be held distinct, so that neither exercise the powers belonging to the other. The subject-matter of this law, if within the legitimate scope of any department of the government, properly belongs to the legislative. It cannot in any sense be considered judicial or executive; and the inquiry is therefore narrowed down to the single question, whether being retrospective in its operation makes it void. As a general and abstract question, the policy and justice of such laws may well be doubted; but how far courts of justice have a right to enter into these considerations, when there is no conflict between the law and the constitution, is a point on which different opinions have been entertained. This court, however, is bound to adopt the view taken of the question by the supreme court of the United States. Although no direct decision upon the point has been made in that court, yet, from what has fallen from the judges on various occasions, when the question has been brought incidentally un.der consideration, the view evidently taken has been, that the validity of such laws, where no constitutional provision was infringed, did not fall within the province of courts of justice.
This question came under the consideration of the supreme court of the United States, at an early day (1798), in the case of Calder v. Bull, 1 Cond. Rep. 172, [3 Dall. (3 U. S.) 386,] though it was not the point on which the judgment of the court turned. Hr. Justice Chase was of opinion that the courts of the United States have no jurisdiction to determine that any law of a state legislature contrary to the constitution of such state, was void; but that such question belonged to the state courts. What fell from Mr. Justice Paterson in that case, would seem to show that the attention of the convention in the formation of the constitution, was *298called to this very subject. He was a member of the convention, and “I had,” says he, "an ardent desire to have extended the provision in the constitution to retrospective law3 in general. There is neither policy nor safety in such laws. It may be truly said of retrospective laws of every description, that they neither accord with sound legislation, nor the fundamental principles of the social compact.” But he did not consider all retrospective laws embraced in the prohibition to the states to pass ex post facto laws: that these words, when applied to a law, must have a technical meaning, and refer to crimes, pains and penalties. Mr. Justice Iredell says, if a government composed of legislative, executive and judicial departments, established by a constitution which imposes no limits on the legislative power, the consequence would inevitably be. 1hat whatever the legislative power chose to enact, would be lawfully enacted, and the judicial power would never interpose to pronounce it void. That if the legislature pass a law within the general scope of their constitutional power, the court cannot pronounce it to be void, merely because, in their judgment, it is contrary to the principles of natural justice.
[NOTE. In Watson v. Mercer. 8 Pet. (33 U. S.) 88, Mr. Justice Story, speaking for the court, said: “It is clear that this court has no right to pronounce an act of the state legislature void, as contrary to the constitution of the United States, from the mere fact that it divests vested rights of property. The constitution of the United States does not prohibit the states from passing retrospective laws generally, but only ex post facto laws. Now, it has been solemnly settled by this court that the phrase ‘ex post facto laws’ is not applicable to civil laws, but to penal and criminal laws, * * * which impose punishments and forfeitures, for acts antecedently done, and not to civil proceedings which affect private rights retrospectively.” An act passed after the rendition of a judgment in favor of a bank, which authorized the defendant therein to set off against it the circulating notes of the bank which he procured after the judgment, is, as between the bank and the defendant, valid, and does not impair the obligation of the contract sued on, or of the judgment. Blount v. Windley, 95 U. S. 180. An act declaring that acts performed by any two of the tax commissioners shall have the same validity as if performed by all three, though retrospective, is not for that reason unconstitutional. Schenck v. Peay, Case No. 12,451. As to the validity of retrospective laws which divest vested rights, see Charles River Bridge v. Warren Bridge, 11 Pet. (36 U. S.) 540; Baltimore & S. R. Co. v. Nesbitt, 10 How. (51 U. S.) 401. There is nothing in the constitution which prohibits a legislature from passing an act which divests rights vested by law, provided its effect be not to impair the obligation of a contract. Randall v. Krieger, 23 How. (90 U. S.) 147. A retrospective statute, remedial in its nature, that confirms existing rights by adding to the means of enforcing existing obligations, may be constitutional. Peay v. Schenck, Case No. 12,449; Griffing v. Gibb, Id. 5,819: Schenck v. Peay, Id. 12,451; Satterlee v. Matthewson, 2 Pet. (27 U. S.) 380; Curtis v. Whitney, 13 Wall. (80 U. S.) 68. An act imposing a higher tax on an incorporated bank than that contemplated in its charter is unconstitutional, as impairing the obligation of a contract. Piqua Bank v. Knoop, 16 How. (57 U. S.) 369.]
*298In the recent case of Satterlee v. Matthewson, (2 Pet. [27 U. S.] 413,) the language of the court is very strong in relation to the powers of the courts of the United States to declare state laws of this description unconstitutional. The objection, say the court, most relied upon is, that the effect of this act was to divest vested rights. There is, certainly, no part of the constitution of the United States which applies to a state law of this description. Nor are we aware of any decision of this court, or of any circuit court, which has condemned such a law upon this ground, provided its effect be not to impair the obligation of a contract. Reference is made to what fell from the chief justice in the case of Fletcher v. Peck, [Case No. 4,865:] That it might well be doubted whether the nature of society and of government do not prescribe some limits to the legislative power; and he asks, if any be prescribed, where are they to be found if the property of an individual, fairly and honestly acquired, may be seized without compensation? But, say the court, it is nowhere intimated in that opinion, that a state statute, which divests vested rights, is repugnant to the constitution of the United States. So in the case of Wilkinson v. Leland, (2 Pet. [27 U. S.] 661,) the court observes: “"We cannot say this is an excess of legislative power, unless we are prepared to say, that in a state not having a written constitution, acts of legislation, having a retrospective operation, are void as to all persons not assenting thereto, even though they may be for beneficial purposes, and to enforce existing rights; and we think this cannot be assumed as a general principle by courts of justice. It may here be remarked, that if the state constitution is entirely silent on the subject, the question stands on the same footing as if there be no written constitution.' In the case of Propagation Soc. v. Wheeler, [Case No. 13,156,] a law, similar to the one in question, was decided in the first circuit to be unconstitutional, but it was put on the ground that it was repugnant to the state constitution, which forbade retrospective laws.
That the law of Vermont, now in question, is a retrospective law, cannot be doubted. It impairs vested rights acquired under existing laws; it attaches a new disability in respect to transactions already past, and creates new liabilities. But it is not repugnant to any provision in the constitution of the Untied States or of the state of Vermont; and this is the sole ground upon which I rest my opinion. Wherever there is a conflict between the law and the constitution, both cannot stand; and it is properly within the province of courts of justice to determine the validity of such a law. But when no such conflict arises, it is matter resting in the discretion of the legislature, who are responsible to the people and are not under judicial control; and although not an advocate for the justice or policy of retrospective laws, I feel less repugnance to the one now under consideration, because similar laws have been in existence in this state almost from its first organization, and having so repeatedly received the sanction of different legislatures, and their validity having been in no manner questioned in the courts of justice, there is reason to conclude that they are satisfactory to the public. We are, accordingly, of opinion that the plaintiffs are entitled to judgment.
