"Government lawyers sided with gas companies urging the justices to revisit a decision by a lower bench that upheld the rules."

"The Trump administration is throwing its weight behind gas providers and utilities that want the Supreme Court to strike down Biden-era Department of Energy rules that tightened standards for gas-powered commercial water heaters and consumer furnaces.

In a brief filed Tuesday, the Department of Justice said because of a “legal error,” the justices should overturn a 2-1 decision by the U.S. Court of Appeals for the District of Columbia Circuit blocking the sale of noncondensing natural gas furnaces and commercial water heaters.

While the D.C. Circuit ruling was a win for DOE, Trump officials said the department holds a different view of the rules following the change in administration."
