More banks are barring consumers from going to court to settle disputes while retail customers overwhelmingly want that right, a Pew Charitable Trusts study released Wednesday shows.

Of the 29 largest banks offering consumer checking accounts, 21 now require consumers to adjudicate complaints, up from 17 in 2013.

In the same three-year period, the percentage of those banks prohibiting retail customers from joining in class-action lawsuits has climbed from 52 percent to 66 percent. At the same time, the share precluding consumers from taking grievances to juries has risen from 79 percent to 93 percent.

Pew said the policies fly in the face of consumer desires.

According to the researchers, 95 percent of adults said complaints against banks should be able to be heard by a judge or a jury while 89 percent want the ability to participate in a class-action lawsuit against a bank.

“Although cost and time constraints would preclude most consumers from taking independent legal action if an issue arose, they want the right to pursue a class-action lawsuit. The high level of interest in access to legal options is consistent across demographic groups such as gender, age, race, income and education,” said Pew.

The think tank said it found it unlikely that opening courts to these kinds of actions would bring a flood of litigation against banks as some financial institutions have contended.

When asked how they would try to settle a dispute with a bank, 75 percent said they would ask to speak to a manager at the institution while only 23 percent said they would go to the courts.

The report comes less than a week before a Monday deadline for public comment on proposed Consumer Financial Protection Bureau rules that would significantly restrict the ability of banks to stop consumers from going to court against them and imposing mandatory arbitration requirements.
