U.S. Supreme Court Justice Stephen Breyer on Monday warned that his colleagues may be poised to overturn court precedents in upcoming cases in ways that will sow “increased uncertainty” about the court's consistency.

Joined by liberal colleagues Ruth Bader Ginsburg, Sonia Sotomayor and Elena Kagan, Breyer dissented in Franchise Tax Board of California v. Hyatt, a state sovereignty case in which the 5-4 majority explicitly overturned a 40-year-old precedent, Nevada v. Hall.

The California case is one of at least four in which the court is being asked to overturn precedents this term.
