Indiana Code Title 36. Local Government § 36-9-37-16

Sec. 16. If a municipality negligently fails to invest or reinvest the special fund in the manner prescribed by section 15 of this chapter, the municipality is liable to the special fund for interest on the fund, calculated at the rate of interest of the bonds issued on account of the assessments.  A holder of bonds upon which prepayments have been made may compel compliance with section 15 of this chapter by mandamus or other appropriate remedy.  However, the failure of a bondholder to compel compliance does not relieve the municipality or any of the municipality's officers from liability under this chapter.
