Burwell, which was joined by a super-majority coalition of justices of diverse ideologies, is a masterpiece of legal craft, good sense and fidelity to law at a time when political polarization threatens to spill over into the judiciary," says professor Neil Siegel, a constitutional law scholar at Duke University's School of Law. "The court has done the nation, and itself, a great service."• Bio:Siegel is a professor of law and political science, co-director of the Program in Public Law and director of the DC Summer Institute on Law and Policy.
