Vt. Stat. tit. 17 § 2662
When any of the requirements as to notice or warning of an annual or special municipal meeting have been omitted or not complied with, the omission or noncompliance, if the meeting and the business transacted at it is otherwise legal and within the scope of the municipal powers, may be corrected and legalized by vote at a regular meeting or special meeting of the municipality called and duly warned for that purpose. The question to be voted upon shall substantially be, "Shall the action taken at the meeting of this town (or city, village or district) held on (state date) in spite of the fact that (state the error or omission), and any act or action of the municipal officers or agents pursuant thereto be readopted, ratified, and confirmed." Errors or omissions in the conduct of an original meeting that are not the result of an unlawful notice or warning or noncompliance within the scope of the warning may be cured by a resolution of the legislative body of the municipality by a vote of two-thirds of all its members at a regular meeting or a special meeting called for that purpose, stating that the defect was the result of oversight, inadvertence, or mistake. When an error or omission of this nature has been thus corrected by resolution, all business within the terms of the action of the qualified voters shall be as valid as if the requirements had been initially complied with, condition, however, that the original action thereby corrected by the legislative body was in compliance with the legal exercise of its corporate powers.
