The US Supreme Court: Politics or the Rule of Law?

This month, the US Supreme Court is expected to decide cases on the limits of speech during abortion protests, organized labor and when police can search your cell phone. Those are cases with important potential consequences for many Americans. They'll be decided by a Court more divided than ever between Democrats and Republicans. Even Justice Stephen Breyer has worried aloud that he and his colleagues are now viewed as "junior varsity politicians." Rulings are supposed to be based on the Constitution and acts of Congress. They can affect the lives of many Americas now and for years to come. Is the Court led by Chief Justice John Roberts pursuing its own agenda? What would that mean for confidence in democracy and the rule of law?
