The defendant answers the former judgment in his favor and the judgment of affirmance in this court, by the title of the case and volume and page of the report, Shepardson v. Green, 21 Wis., 539, setting out by way of exhibit annexed to the answer the former récord here verbatim and at length, and insisting upon the same as a bar and absolute estop-pel of the rights claimed by the plaintiff in this suit. This is the only question presented by the demurrer to the answer: Is the former judgment a bar to the relief demanded in this suit ? The former was an action at law by the plaintiff against the defendant, to recover damages for the conversion of' the same lot of coal mentioned in the warehouse receipt set out in the complaint in this suit and dated November 1, 1864. The complaint in that action was general, as in such cases, averring title and possession of the property in the plaintiff on a certain day, and that it afterwards came to the possession of the defendant, who, well knowing it to be the property of the plaintiff, and *38though often requested, etc., bad'not delivered tbe same to tbe plaintiff,.but on tbe contrary bad converted and disposed of- it to bis own use. Tbe answer was a general denial, and in addition a special claim of title in tbe defendant under tbe bill, of sale from Dowe, Tibbets & Co. to hjm.
Tbis suit purports to be one in equity, instituted for tbe purpose of enforcing wbat is termed tbe equitable lien created in favor of tbe plaintiff by virtue of tbe same instrument, denominated a warehouse receipt. Sucb equitable right or lien of tbe plaintiff, it is claimed and insisted on bis part, is not barred or affected by tbe former judgment. It is obvious, whatever may have been tbe rights of tbe • plaintiff under tbe instrument called a warehouse receipt, set out in tbe complaint in tbis suit, and given in evidence by tbe plaintiff on tbe trial of tbe former action as tbe foundation of bis claim and right to recover in that, and which, from tbe averments now contained in tbe complaint, appears actually to have been a warehouse receipt, that all sucb rights might have been amply vindicated, and full and adequate redress given in tbe former action at law. Tbis is obvious in whatever light tbe instrument may be regarded, or whatever may be, or might then have been, considered its nature and effect, and whether tbe rights of tbe plaintiff be looked at as legal or equitable, or both.
If, for example, it. be regarded as a chattel mortgage, or a sale or assignment in tbe nature of one, thus giving tbe plaintiff certain legal and equitable rights, as against tbe makers, Dowe, Tibbits & Co., or against others, tbe action at law was ample for tbe protection and enforcement of all such rights. Grant that tbe remedy in equity existed by reason of tbe lien and equitable right, and might have been resorted to before tbe, action at law was commenced, tried or determined, still tbe latter was, by reason of tbe legal title and right at law, a remedy of equal usefulness and efficacy. If equity will enforce tbe lien of tbe mortgage in sucb cases, and work out and compel satisfaction of tbe mortgage debt,, from tbe property in tbe *39bands of tbe mortgagor, or other party bolding it subject to tbe mortgage, or decree payment of tbe debt by tbe mortgagor, or such other party who has converted or disposed of the property in fraud of the mortgagee, or so as to deprive him of bis lien or right, tbe law, though upon somewhat different principles, and by a different method, will accomplish the same practical result, and-afford a no less efficient and adequate remedy. The law will do this by just such an action as that first instituted by this plaintiff. It will give the mortgagee, provided as such he is entitled to recover against the defendant at all, damages for the conversion of the property to the full extent or value of his lien upon or interest in the property. This is all that equity could do by adjudging compensation to be made, under the circumstances of this case.
The remedy at law, therefore, founded on the legal title or right, is equivalent to that given in equity, founded on the equitable title or lien. It is in every case co-extensive and concurrent with the remedy in equity, and being so, it would seem necessarily to follow that the judgment in an action at-law would bar and estop the party subsequently resorting to his suit in equity upon the same subject or ground of action, and vice versa. Indeed, it is well settled that this is so. See Pierce v. Kneeland, 9 Wis., 23. Simpson v. Hart, 1 John, Ch. R., 91.. If the property be in existence so that chancery can take hold of and enforce satisfaction of the debt by a sale of it, there the mortgagee-or creditor has also his action of replev-. in, to obtain possession of the property at law, and in that way to compel satisfaction. Under all circumstances, therefore, the legal and equitable remedies seem to be concurrent and coequal, and a final judgment in one forum a bar to further agita-, tion and controversy with respect to the same subject matter in the other. If the mortgagee should bring replevin for the property, and be defeated in the action on the ground that his mortgage was void, or not a lien upon the property in the possession of the defendant, it could not be tolerated that he might *40then bring his suit in equity and compel the defendant to litigate the same questions over again in that court, upon the ground of his supposed equitable title or lien. His entire right or title would be involved in the issue at law, and that decision would be res adjudicóla in the court of equity. And the same result must follow where the proceeding at law is in trover or other form of action to recover damages for the taking or conversion of the property, and it is adjudged against the plaintiff on the merits, that his mortgage is void, or that he has no title to or lien upon the property as against the defendant.
For these reasons, therefore, regarding the instrument in question as a mortgage, the former adjudication, plead and relied on in the answer as a bar, must be held good and sufficient for that purpose; and for the same reasons the authorities cited by counsel for the plaintiff are inapplicable. This is not an equitable right which could not be reached or redressed in the action of law. It was as a mortgage that the instrument was presented for the consideration of the court in the former action, and the rights of the plaintiff urged under it. It was as such that it was treated, spoken and judged of by the court, and held not to be valid against the defendant, although he purchased or paid* for the property with notice of the plaintiff’s claim. It was so held on the language of the statute and on the authority of Single v. Phelps, 20 Wis., 398. The statute declares that no mortgage of personal property made after its passage shall be valid against any other person than the parties thereto, unless possession of the mortgaged property be delivered to and retained by the mortgagee, or unless the mortgage or a copy thereof be filed in the office of the town clerk where the mortgagor resides. It appeared in that case, as it does in this, that the plaintiff had neither taken nor retained possession of the property under the instrument claimed to be a mortgage nor filed it or a copy of it in the town clerk’s office, at the time the defendant purchased and received possession of the property from the alleged mortgagors.
*41But there is still another reason, regarding the instrument as a mortgage or in the nature of one, why this application in equity must prove unavailing. If a mortgage, it was under the operation of the statute equally yoid as to the defendant in equity as at law, for want of filing in the town cleric’s office, or of possession of the property taken and held, by the plaintiff under it. Equity no more than the law can disregard the positive provision of a statute; and as relief in equity could not be granted without overthrowing the statute, it would follow that the suit must be dismissed, even though there were no previous adjudication standing in the way of a recovery, and still more if there was one.
There seem to be but two other characters, besides as a mortgage, in which effect might have been given to the instrument in favor of the plaintiff. One was as a bill of sale from Dowe, Tibbits & Co. to him of the property left by him in their possession, and subsequently bought of them or paid for by the defendant with knowledge of the rights of the plaintiff. The bill of exceptions in the former case, transcribed into the answer in this, showed that the defendant paid the full amount of the purchase money to the Merchants’ Bank and Juneau Bank, creditors of Dowe, Tibbits & Co., according to the terms of the bill of sale, after he had notice of the claims of the plaintiff. In that view, it might have been said that the defendant was not a subsequent purchaser in good faith and that the plaintiff had the better title, unless the defendant was entitled to stand in the place of and represent the creditors of Dowe, Tibbits & Co., for whose benefit the sale to him was made, and to whom he paid the purchase money. R. S., ch. 107, § 5. The transaction was not considered in this light, nor the 'effect of it as a sale either absolute or conditional determined.
The other view which might have been taken of the instrument, and which under proper circumstances might have resuited beneficially to the plaintiff, was, that it was a warehouse receipt. Such was the form of the instrument, and the effect *42tobe given to it according, to its words, and, as already observed, sucb now by tbe averments of tbe present complaint appears to bave been tbe real nature of it. It is now averred in tbe complaint and admitted by tbe demurrer that tbe makers, Dowe, Tibbits & Co,, were in fact warehousemen, engaged in tbe transaction of that business, as well as coal and wood merchants. Tbe fact did not formerly appear, either by averment in tbe pleadings or by proof on tbe trial. Tbe facts then shown were —we quote from tbe bill of exceptions — “ that they were dealing in coal, and from tbe time of its receipt by them, until taken by tbe defendant, they were engaged in selling and delivering the same to their customers in tbe usual course of their business, and receiving tbe proceeds thereof and appropriating them to their own uses and purposes.” Tbe fact that they were warehousemen, assuming them to bave been such, was not there shown. Proof of their character as sucb was necessary in order to give effect to tbe instrument as a warehouse receipt.
Tbe court could not take judicial notice that they were ware-housemen, nor presume it as a fact from tbe mere issuing of tbe receipt. Actual proof was necessary in order to make an effectual transfer of tbe property in that way; for otherwise it would be competent for every person, whether warehouseman or not, thus to dispose of personal property in bis possession, to' tbe great embarrassment and deception of subsequent purchasers, creditors and others.
To uphold tbe receipt as a proper warehouse document, trans-férring tbe title to tbe property and operating as a good constructive delivery of it to tbe vendee, it must in all eases distinctly appear that it was executed by a warehouseman — one openly engaged in that business — and in tbe usual course of trade, without fraud or intention of fraud or bad faith on tbe part of tbe person receiving and seeking to enforce title under it. In tbe former case, therefore, if for no other reason, tbe plaintiff could not bave maintained title against tbe defendant upon tbe instrument as a warehouse receipt, because there was *43no proof of the business character of the maters, or evidence that they were warehousemen.
But in whatever light the instrument might then have been examined or on whatever ground the cause decided adversely to the plaintiff, holding that he had no title to the property as against the defendant, the judgment is now equally a bar and conclusive upon the rights of the plaintiff, whether upon the instrument as a chattel mortgage, bill of sale, or warehouse receipt, the title of the plaintiff was maintainable, the judgment now concludes him both at law and in equity. Under the pleadings and issue as presented it was competent for him to sustain his title on either ground, if valid; and if, for want of proof of particular facts or for other cause, or because the court took an erroneous view of the law, judgment went against him and the title of the defendant was decided to be superior, it is res adjudicata and cannot again be inquired into or litigated in another suit between him and the defendant. It is a familiar principle in the law of estoppel by judgment, that the judgment is final and concludes not only as to the matters determined, but as to all matters which the parties might have ligitated, and which they might have had decided under the pleadings and issue joined in the action. Eastman v. Porter, 14 Wis., 39, 48, 49. It is the decision by a court of competent jurisdiction that the defendant had the superior title, which binds, and it is immaterial what was the ground or what the reasons assigned by the court for making it.
We cannot conclude our examination of this case, or close our remarks upon it without some observations upon the language of the opinion in the former case, the effect of the judgment in which has been the subject of consideration here. 21 Wis., 541, 542. The language of that opinion undoubtedly proceeds upon a misconception or erroneous view of .the law with respect to the effect of a warehouse receipt as an instrument transferring the legal title and constructive possession of the property to the holder of it, and protecting him against a *44subsequent sale or transfer of the same property by tbe warehouseman, even to a purchaser without notice, and against the the creditors of the warehouseman who may subsequently seize property in his possession in satisfaction of their demands. The law on this subject was correctly held in Gibson v. Stevens, 8 How. (U. S.), 384, in Gibson, Stockwell & Co. v. The Chillicothe Bank, 11 Ohio St. R., 310, and in Rice v. Cutler, 17 Wis., 351, to be that the execution and delivery by the warehouseman of the receipt, carries the vendor’s title and constructive possession of the property to the vendee, who, or the party claiming under him, as the holder of the receipt, is thenceforth, in cases free from fraud or bad faith, or it may be of mistake, regarded as the owner of the property for all purposes, and the warehouseman as mere bailee, having the custody of it for the benefit of the vendee or other holder of the receipt, and subject to his order and control. The relation between the parties and their rights and obligations are considered the same as if the vendee had purchased the property from some other owner, and then placed it in the warehouseman’s possession, taking his receipt in the same form. Such relation, and the consequent rights and obligations of the parties are held by the decisions just referred to, even where the sale is made as collateral security for the payment of a debt due from the warehouseman, not to be affected by the statute regulating the making and filing of mortgages of personal property, nor by the act concerning warehouse receipts and bills of lading. Whether the same effect would be ascribed to a bill of lading or receipt by a common carrier of goods sold by him and left in his possession tobe transported for the benefit of the vendee and subject to his order, or the order of the in-dorsee or holder of the bill of lading or receipt, it is unnecessary now to inquire. We know of no case in which this point has been presented and decided, as it has been with respect to the receipt of a warehouseman or wharfinger..
