Wis. 60; Boorman v. Juneau Co. 76 Wis. 550; Green Bay & M. Canal Co. v. Outagamie Co. 76 Wis. 587; Kaehler v. Dobberpuhl, 56 Wis. 480; Hixon v. Oneida Co. 82 Wis. 515. It is the settled doctrine of this court that it is not enough to avoid a tax in equity to show that the proceedings were-irregular or even void, but, in addition, it must also be shown that the taxes were inequitable (Hixon v. Oneida Co., supra),. that, where taxes are legal or, whether strictly legal or not,, are just and equitable, and are joined with such as are illegal and inequitable, the illegal excess, if it can be separated, is only conditionally voidable in equity, the condition being payment of the balance of the taxes. Wis. Cent. R. Co. v. Lincoln Co., supra. Such equitable rule has been crystallized into legislative enactments, several of which followed promptly upon, and may safely be assumed to have been caused by, holdings of this court supposed to constitute a departure from the early rule governing the subject. The-court promptly retraced its steps in that regard, gave full effect to such legislative enactments, and carried the spirit of the rule into effect in respect to all questions affecting taxation to which it was applicable, so that, as said by Mr. Justice Taylor in Fifield v. Marinette Co., supra: “ The effect is to compel every taxpayer who comes into a court of equity to void his taxes for any cause to first pay such taxes on his property as he ought in justice to pay.” Since the decision in that case, the legislative policy in that regard, has been still more pronounced, as shown in Day v. Pelican,. 94 Wis. 503, construing sec. 1164, S. & B. Ann. Stats., which provides that every person aggrieved by the levy and collection of any unlawful tax assessed against him in any town,, city, or village may sue for recovery of all moneys so unlawfully levied and collected of him, “ provided, however, that no action shall be maintained under the provisions of this, section unless it shall-be made to appear to the court that the plaintiff has paid more than his equitable share of such,
