If, in the opinion of the council, any assessment heretofore or hereafter issued is void or unenforceable for any cause, or if bonds are issued to represent or be secured by any assessments and such issuance is not effective through the curative provisions applicable thereto to make them valid and enforceable, or if the council shall determine that the public interest will be served thereby, a reassessment may be had.
