against any municipality in the state of New York, or its proper
officers, arising from the action of such municipality in derogation of
its previous grant or covenant, where a previous action shall not have
succeeded, in whole or in part, owing to the failure of the said
municipality to produce or prove certain written evidence, which was
essential to the plaintiff's claim, shall not be barred by the operation
of the statutes limiting the time for the enforcement of civil remedies
in favor of the successor in interest to the person entitled to any
