What it's about

The Supreme Court ruled that collecting those fees without affirmative consent violates the First Amendment, overturned Abood’s rule, overturned the Seventh Circuit’s judgment, and sent the case back to the lower court (remanded).

The case revisited a decades-old rule about public-sector union fees and the First Amendment.

Question presented

Should Abood be overruled and public sector agency fee arrangements declared unconstitutional under the First Amendment?

What the Court decided

Holding

The State’s extraction of agency fees from nonconsenting publicsector employees violates the First Amendment. Abood erred in concluding otherwise, and stare decisis cannot support it. Abood is therefore overruled. For these reasons, States and public-sector unions may no longer extract agency fees from nonconsenting employees. The First Amendment is violated when money is taken from nonconsenting employees for a public-sector union; employees must choose to support the union before anything is taken from them. Accordingly, neither an agency fee nor any other form of payment to a public-sector union may be deducted from an employee, nor may any other attempt be made to collect such a payment, unless the employee affirmatively consents to pay. 851 F. 3d 746, reversed and remanded.

From the opinions

“For over 40 years, Abood v. Detroit Bd. of Ed. , 431 U. S. 209 (1977), struck a stable balance between public employees’ First Amendment rights and government entities’ interests in running their workforces as they thought proper.”

— Justice Kagan(dissent)

What's next

The Supreme Court sent the case back to the Seventh Circuit (remanded) for further proceedings. Its consent rule now controls whether an agency fee or other payment to a public-sector union may be deducted.
