The U.S. Supreme Court on Monday declined to take up Puerto Rico teachers unions’ appeal to challenge the island’s historic debt and pension restructuring plan, Bloomberg Law reported. The justices’ decision to bypass keeps in place the restructuring plan’s provisions that upend local laws and reduce teacher benefits. The commonwealth’s financial reorganization plan, approved by a federal judge earlier this year, remains free from any further challenge by disaffected teachers who tried to fight cuts to their accrual of pension benefits.
