In summary

Cases pending before the state Supreme Court could have a huge impact on the pensions of public employees. They specifically involve challenges to a mild pension reform sponsored by Gov. Jerry Brown but could result in a broader ruling that would open the door to pension benefit reductions.

California’s public employee unions suffered a potentially heavy blow this year when the U.S. Supreme Court declared that they could not charge “fair share fees” to non-members.

Union leaders and their political allies – essentially the entire Democratic Party – feared that the ruling (Janus vs. AFSCME) would entice many civil service workers to drop their union memberships, sharply reducing dues income that has been a prime source of political campaign financing.

Those fears were hopes for those on the other side of the state’s political spectrum – conservative interest groups and Republicans. So far, however, the fallout has been scant.

Many unions have declared that those seeking to drop their memberships must wait until contracts with state and local governments expire and/or they must pay “service fees” if they exit. Those provisions have touched off a flurry of lawsuits contending that such footdragging violates the Supreme Court’s decision.

Meanwhile, public employee unions are awaiting another judicial decree, this one from the state Supreme Court, that also has high stakes.

Six years ago, Gov. Jerry Brown and the Legislature enacted a relatively mild reform of public employee pensions – lowering potential benefits for new workers, compelling employees to make bigger contributions and eliminating maneuvers that allowed workers to inflate their pension checks.

All were aimed at slowly reducing the huge “unfunded liabilities” plaguing the California Public Employees Retirement System (CalPERS) and local pension trust funds, thanks to investment losses during the Great Recession, surging baby boomer retirements, longer lifespans and, finally, very sharp increases in benefits in the last decade.

Several unions disliked the reforms and sued, saying they violated what’s been termed the “California rule.” It’s a long-standing assumption, based on a 1955 state Supreme Court ruling, that pension benefits in place at the moment of a worker’s hiring can never be reduced without equivalent compensation.

One suit, brought by a state firefighter union, challenged the governor’s elimination of “airtime” – the ability for a worker to purchase additional years of service credit – on the assertion that it violated the California rule.

The suits resulted in a flurry of somewhat contradictory appellate court rulings, thus opening the legal door for the state Supreme Court to not only decide the specific issues, but possibly render a broader judgment on whether the California rule is sacrosanct.

The Supreme Court heard oral arguments on the merged cases this month and it was evident that its justices are somewhat uncertain over whether to issue a narrow ruling on airtime and other specifics of the governor’s reforms, or delve into the California rule.

One appellate ruling in a Marin County case, involving the reform plan’s elimination of “pension spiking,” essentially declared that the California rule isn’t binding as long as employees receive “substantial and reasonable” pensions.

Were the Supreme Court to adopt that attitude, it would open the door to freezing pension benefits already earned by employees and adopting lower benefits for future work.

Such a ruling would please local government officials, who are faced with rapidly rising demands from CalPERS for more money to shrink the trust fund’s stubborn unfunded liability, driving some cities to the brink of insolvency and/or forcing them to ask voters for more taxes.

It would give city officials leverage to place pension benefits on the table during union contract negotiations. It would give unions a black eye for trying to overturn Brown’s reform. And it would give the governor, who took personal charge of the pension legal battle, a big bullet point in his legacy.
