Foreclosure actions and proceedings against municipality by holders of bonds

1. If any assessment or installment thereof is not promptly collected or enforced, then any bondholder may file and prosecute a foreclosure action in the name of the municipality. Any bondholder may also proceed against such municipality to protect and enforce the rights of the bondholders under the Consolidated Local Improvements Law, or under any charter adopting the provisions hereof or referring hereto for a method of collecting assessments, or any ordinance required or permitted thereunder, by suit, action or special proceedings in equity or at law, either for the appointment of a receiver or for the specific performance of any provisions contained herein or in such ordinance or in an award of execution of any power granted herein or in such ordinance for the enforcement of any proper, legal or equitable remedy as such bondholder or bondholders may deem most effectual to protect and enforce the rights aforesaid. 2. All such proceedings at law or in equity shall be instituted, had and maintained for the equal benefit of all holders of the bonds then outstanding. The failure of the bondholders so to foreclose such delinquent assessments, or so to proceed against the municipality, or both, shall not relieve the municipality or any of its officers, agents or employees of any liability for its failure so to foreclose such delinquent assessments.
