Federal courts have halted a major infrastructure project pending congressional approval, prompting the Supreme Court to step in and temporarily reverse the lower court rulings. Legal disputes over whether the project requires explicit legislative authorization have escalated, raising questions about executive authority and federal oversight. With construction paused, the justices’ intervention signals a high-stakes showdown over how such large-scale initiatives can proceed without direct congressional consent. The case underscores broader tensions between branches of government on the scope of administrative power.


The justices intervened Monday after lower courts found work must stop because the project doesn't have congressional approval.
