Validity; immaterial errors

Wis. Stat. § 75.22

in effect

If after the issuance of a tax certificate or conveyance to the county of any lands subject to a tax certificate and within the time hereinafter prescribed it shall be discovered that the certificate was invalid, the county board shall make an order, briefly stating the reason therefor, directing that the certificate, as it applies to the affected lands, or deed be canceled. But no certificate or conveyance shall be deemed invalid within the meaning of this section by reason of any mistake or irregularity in any of the tax proceedings not affecting the groundwork of the tax; nor shall any county be liable to pay or refund any moneys by reason of any such mistake or irregularity.
