The bill, SB 33, was authored by Sen. Bill Dodd (D-Napa) and sponsored by State Treasurer
Wells Fargo, like many financial institutions, requires customers to give up their right to sue when they sign up for personal accounts and other services.
The use of arbitration clauses became controversial after Wells Fargo admitted last year that its employees had created millions of checking, savings, credit card and other accounts without customers' knowledge or permission.
Both before and after the September 2016 admission, Wells Fargo cited the clauses to successfully shield itself from lawsuits filed over the bogus accounts, even though customers have never agreed to open them.
Critics of private arbitration say that it is stacked against consumers and that it helps large companies keep wrongdoing under wraps.
Wells Fargo Chief Executive Timothy Sloan was sharply questioned about the bank’s position on arbitration during a Tuesday hearing held by the
Sloan testified that the bank was no longer taking the position that its arbitration clause prevents customers from suing the bank, but was told by Sen. Chris Van Hollen (D-Md.) that at least in one lawsuit the bank still held that position.
SB 33 faced opposition from the California Chamber of Commerce, California Bankers Assn. and other business groups, which argued it would likely lead to years of costly litigation and ultimately be invalidated by federal courts.
Over the last few decades, the U.S. Supreme Court has issued opinions in several arbitration-related cases, generally saying that states cannot make rules that disfavor arbitration and that state courts must honor arbitration agreements. The new state law applies to both federally chartered and state-chartered banks.
Alan Kaplinsky, a Philadelphia attorney who pioneered the use of arbitration clauses, told The Times this spring that if the bill becomes law, he believes the Supreme Court would eventually overturn it.
"It clearly won't stand up," he said. "Really, there's no doubt at all that the state law would be preempted."
However, neither measure has moved forward in the Republican-controlled Congress.
A Wells Fargo spokeswoman said she was unable to provide immediate comment on the governor's action.
