After the U.S. Supreme Court’s historic decision barring employers from firing workers based on their sexual orientation or gender identity, a series of cases pending before the justices asks them again to confront discrimination against LGBT individuals.

On Monday, the justices formally requested the views of the U.S. solicitor general in a case brought by Texas against what it calls California’s “blacklisting” of states with certain laws allowing discrimination against LGBT persons. The court also has set oral arguments for next term in the case Fulton v. City of Philadelphia. That dispute centers on the city’s anti-discrimination rules regarding foster care services.
