The Supreme Court rejected the independent state legislature theory in a bombshell decision Tuesday, turning back a right-wing attempt to vest the sole power in administering federal elections with state legislatures.
SCOTUS just soundly rejected an idea called "independent state legislature theory" in a case called Moore v. Harper. Here's a good summary of the implications if it had been upheld:
"Proponents of the independent state legislature theory reject this traditional reading, insisting that these clauses give state legislatures exclusive and near-absolute power to regulate federal elections. The result? When it comes to federal elections, legislators would be free to violate the state constitution and state courts couldn’t stop them."
