'No sale of property for taxes shall be set aside for any cause, except on proof of dual assessment, or of payment of the taxes for which the property was sold prior to the date of the sale, unless the proceeding to annul is instituted . . . within three years from the adoption of this Constitution, as to sales already made.'

The state Constitution of 1898 was adopted and went into effect May 12, 1898. La. Const. 1898, p. 88. ”
