Miss. Code Ann. § 31-19-7: Miss. Code Ann. § 31-19-7

Whenever, pursuant to statutory authority, bonds of the State of Mississippi, or of any county, municipality, road district, supervisors district, school district, drainage district, or other taxing district therein, have been or shall hereafter be prepared and signed by the officials designated to sign the bonds by statute or by the proceedings authorizing the issuance of the bonds, who were or are in office at the time of such signing but who may have ceased to be such officials prior to the sale and delivery of such bonds or who may not have been in office on the date such bonds may bear, the signatures of such officials upon such bonds and the coupons thereto attached are valid and sufficient for all purposes and shall have the same effect as if the persons so officially signing such bonds had remained in office until delivery of the same to the purchasers or had been in office on the date such bonds may bear, although the term of office of such persons or any of them may have expired or they may otherwise have ceased to be such officers before such delivery or although the term of office of such persons or any of them may not have commenced until a date subsequent to the date such bonds may bear. All such bonds heretofore or hereafter executed and heretofore or hereafter sold and delivered are hereby ratified, validated, and confirmed, notwithstanding any change in office which may have taken place subsequently to the execution of the bonds and coupons and prior to the delivery thereof or any change in office which may have taken place subsequently to the date which such bonds may bear and prior to the execution and delivery thereof; and such bonds shall be valid and binding obligations of said state, county, municipality, road district, supervisors district, school district, drainage district, or other taxing district, as the case may be.
