Bork also advocated modifying the Constitution to allow Congressional super-majorities to override Supreme Court decisions, similar to the Canadian notwithstanding clause. Though Bork had many liberal critics, some of his arguments have earned criticism from conservatives as well. Although an opponent of gun control, Bork denounced what he called the "NRA view" of the Second Amendment, something he described as the "belief that the constitution guarantees a right to Teflon-coated bullets." Instead, he argued that the Second Amendment merely guarantees a right to participate in a government militia.
