The Howard Jarvis Taxpayers Association and California Foundation for Fiscal Responsibility won a lawsuit against Contra Costa County in July 2009. A court ruled that the organizations are entitled to a list of names and total retirement benefits for all Contra Costa County employees receiving an annual pension of at least $100,000. The taxpayer groups argued that the records should be public because (unlike the IRA and 401k plans of private citizens), the public employee benefit plans pay a guaranteed amount and are funded by taxpayers. Contra Costa Superior Court Judge Barry Baskin ruled in favor of the groups, saying a "transparent government is the cornerstone of our democracy."
To meet new public pension financing rules, Contra Costa County, along with five others, would have to dedicate all of their existing property taxes to pay for pensions or pursue municipal bankruptcy through the courts, according to a report by Moody’s municipal credit rating agency. Moody’s proposed changes in evaluating pension funds are: 
- The assumed rate of return on pension fund investments will be lowered from 7.75 percent to 5.5 percent. The lower the interest rate on pension fund investments, the larger the cash contribution required by employees or counties. Public pension funds have assumed unrealistically high investment return rates based on inflation during the Mortgage Bubble.
- Municipalities will be required to catch up on its unfunded pension liabilities in 17-years, not the 20 to 30 year period now used.
- Full payment of borrowed principal and interest – called full amortization — will be required in making pension payments. This means that level payments will be required, not graduated payments that start low and rise over time.
