The bankruptcy of Vallejo, California redefined the concept of municipal solvency under Chapter 9. While Vallejo had $136 million in cash reserves, the court determined this was restricted funding with legal obligations and could not be used to address immediate needs, establishing that a municipality can be insolvent prospectively. This precedent gives municipalities leverage in negotiations with unions by establishing bankruptcy as a real option to restructure agreements. Many cities have since implemented two-tier wage systems, outsourced services, or taken other steps to restructure costs in response to the new landscape created by the Vallejo decision.
