Justice Stephen Breyer, a pragmatic jurist whose opinions over the last 27 years are infused with a commitment to making democracy work, is retiring, according to media reports, opening a spot for President Joe Biden’s first appointment to the U.S. Supreme Court.

Breyer’s successor would not change the ideological balance on the court, which currently has a 6-3 conservative majority. A Biden appointee, if confirmed, would join the court’s two remaining Democratic appointees on the left, Justices Sonia Sotomayor and Elena Kagan.
