Which states protect pension benefits from impairment or diminishment and what cities within those states have unfunded pension liabilities of at least $1 billion?
There are several states that protect pension benefits from impairment or diminishment, including Illinois, Michigan, California, and Pennsylvania.
In Illinois, the state constitution has been interpreted to protect pension benefits, making it difficult for cities to reduce pension obligations for current and future employees. One city in Illinois that has a significant unfunded pension liability is Chicago, which has an unfunded liability of around $30 billion for its public employee pension funds.
In Michigan, the state constitution protects public pension benefits, but the state has also enacted laws that allow cities to modify future pension benefits for current employees. One city in Michigan that has a significant unfunded pension liability is Detroit, which filed for bankruptcy in 2013 in part due to its pension obligations.
In California, the state constitution also protects pension benefits, and there are several cities in the state with significant unfunded pension liabilities, including Los Angeles, with around $10 billion in unfunded liabilities, and San Francisco, with unfunded obligations currently estimated at around $4.4 billion.
In Pennsylvania, the state constitution has a strong protection of pension benefits. One city in Pennsylvania that has a significant unfunded pension liability is Philadelphia, which has an unfunded liability of over $10 billion for its public employee pension funds.
It is worth noting, however, that even in states where pension benefits are protected, there may still be opportunities to modify pension obligations through negotiations with employee unions or other legal avenues.
