When any of the requirements as to notice or warning of a special District meeting have been omitted or not complied with, if the meeting and the business transacted is otherwise legal, the omission or noncompliance may be corrected and legalized by vote at a special meeting of the District called and duly warned for that purpose. The question to be voted upon shall substantially be:  "Shall of the action taken at the meeting of the District held on (state date), in spite of the fact that (state the error or omission), and any act or action of the District officers or agents pursuant thereto be readopted, ratified, or confirmed?"  Errors or omissions in the conduct of any prior special meeting which 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 Board of the District by a vote of at least two-thirds of all the votes entitled to be cast at a regular meeting or a special meeting called for that purpose, stating that a defect was the result of an oversight, inadvertence, or mistake. When an error or omission has thus been 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 in compliance initially on the condition that the original action by the Board was otherwise in compliance with the legal exercise of its corporate powers.
