Birds on the Brain

(CBS News) Chief Justice John Roberts initially sided with the Supreme Court’s four conservative justices to strike down the heart of President Obama’s health care reform law, the Affordable Care Act, but later changed his position and formed an alliance with liberals to uphold the bulk of the law, according to two sources with specific knowledge of the deliberations.

The conservatives refused to join any aspect of his opinion, including sections with which they agreed, such as his analysis imposing limits on Congress’ power under the Commerce Clause, the sources said.

Instead, the four joined forces and crafted a highly unusual, unsigned joint dissent. They deliberately ignored Roberts’ decision, the sources said, as if they were no longer even willing to engage with him in debate.

The inner-workings of the Supreme Court are almost impossible to penetrate. The Court’s private conferences, when the justices discuss cases and cast their initial votes, include only the nine members - no law clerks or secretaries are permitted. The justices are notoriously close-lipped, and their law clerks must agree to keep matters completely confidential.
