Shortly before Associate Justice Stephen Breyer’s 28-year tenure at the Supreme Court of the United States ends (Noon Eastern time) today, the Supreme Court will release the final pair of major decisions remaining in the 2021 term. West Virginia versus the Environmental Protection Agency will determine the EPA’s authority to issue major rules, while the second will decide whether President Biden will be compelled to enforce the 2019 “Remain in Mexico” policy, formally known as the Migrant Protection Protocols. After Justice Breyer’s official retirement, incoming Associate Justice Ketanji Brown Jackson will be sworn in as the newest Justice -and first black female- to serve on the high court. Breyer, nominated to the court by President Bill Clinton in 1994 was the second-longest service justice on the court behind Clarence Thomas, who joined in 1991.
