At finish line, U.S. Supreme Court readies climate, immigration rulings

[June 30, 2022]  By Andrew Chung and Lawrence Hurley

WASHINGTON (Reuters) - The U.S. Supreme Court is set on Thursday to issue its final two rulings of its current term, one on federal agency power to tackle climate change and the other on President Joe Biden's ability to end a hardline immigration policy begun under his predecessor Donald Trump.

Thursday also will mark liberal Justice Stephen Breyer's last day as a member of the top U.S. judicial body. Breyer, who announced in January plans to retire after serving since 1994, will officially step down and his replacement, Biden's appointee Ketanji Brown Jackson, will be sworn in at noon (1600 GMT), the court said.

The justices also are expected to announce possible new cases they will hear in their next term that begins in October. It has been a momentous term powered by the court's increasingly assertive 6-3 conservative majority, as exemplified by last week's rulings overturning the 1973 Roe v. Wade landmark that legalized abortion nationwide and expanding gun rights.

In Feb. 28 oral arguments in the climate case, the conservative justices appeared skeptical of the federal government's authority to issue sweeping regulations to reduce carbon emissions from power plants in a case that could undermine Biden's plans to tackle climate change.

The court is considering the Environmental Protection Agency's (EPA) authority to regulate greenhouse gas emissions from existing coal- and gas-fired power plants under the landmark Clean Air Act environmental law.

A ruling restricting the EPA's authority could hamstring the administration's ability to curb the power sector's emissions - representing about a quarter of U.S. greenhouse gases. The United States, behind only China in greenhouse gas emissions, is a pivotal player in efforts to combat climate change globally.

The court on April 26 heard arguments in a legal fight over Biden's bid to rescind Trump's "remain in Mexico" policy that forced tens of thousands of migrants to stay in Mexico to await U.S. hearings on their asylum claims.

Biden's administration has appealed a lower court ruling reinstating Trump's policy after the Republican-led states of Texas and Missouri sued to maintain the program. Biden suspended Trump's policy, which had changed longstanding U.S. practice, in January 2021 shortly after taking office and acted to rescind it five months later.

Trump's administration adopted the policy, formally known as the "Migrant Protection Protocols," in response to an increase in migration along the U.S.-Mexican border in 2018. The policy prevented certain non-Mexican migrants, including asylum seekers fearing persecution in their home countries, from being released into the United States to await immigration proceedings, instead returning them to Mexico.

The Senate on April 7 confirmed Jackson on a vote of 53-47, with three Republicans joining Biden's fellow Democrats. Breyer, at 83, is the oldest of the nine justices. Jackson, 51, is a federal appellate judge. All but three of the 115 justices who have served on the high court have been white, with two Black members, including current Justice Clarence Thomas, and one Hispanic, current Justice Sonia Sotomayor.
