Subject to any contractual limitations binding upon a bondholder or his trustee, any bondholder or his trustee has the remedies set forth in this article for the equal benefit and protection of all bondholders similarly situated.

Such contractual limitations include, but are not limited to, any limitation upon the exercise of a remedy to bondholders or their trustees holding a specific percentage of the bonds.

By mandamus or other suit or proceeding at law or in equity a bondholder or his trustee may enforce his rights against the local agency, its legislative body, and any of its officers, agents, and employees and compel them to perform and carry out their duties under this chapter and their agreements with bondholders.

By a suit in equity a bondholder or his trustee may require the local agency and its legislative body to account as the trustee of an express trust.

By suit in equity a bondholder or his trustee may enjoin any acts or things which are unlawful or violate the bondholders’ rights.

The remedies conferred upon any bondholder or his trustee by this chapter do not exclude any other remedy. Each remedy is cumulative and in addition to every other remedy and may be exercised without exhausting and without regard to any other remedy conferred by this chapter or other law.

A waiver of any default or breach of duty or contract by any bondholder or his trustee does not affect any subsequent default or breach of duty or contract nor impair any rights or remedies on the subsequent default or breach.

The delay or omission of any bondholder or his trustee to exercise any right or power accruing upon any default does not impair the right or power and is not a waiver of the default or acquiescence in it.

Every substantive right and remedy conferred upon the bondholders or their trustee may be enforced and exercised as often as is deemed expedient.

If a suit, action, or proceeding to enforce any right or exercise any remedy is abandoned or determined adversely to the bondholders or their trustees, the local agency and bondholder or trustee shall be restored to their former positions, rights, and remedies as if such suit, action, or proceeding had not been brought or taken.
