23. No objection founded upon form, or upon the omission of any formality, even imperative, in any act or proceeding relating to municipal matters, can be allowed to prevail in any civil action, suit or proceeding respecting such matters, unless substantial injustice would be done by rejecting such objection, or unless the formality omitted be such that its omission, according to this Code, would render null the proceedings or other municipal acts requiring such formality.
