No Stare Decisis ? No Second Amendment?

Stare Decisis:

[Latin, Let the decision stand.] The policy of courts to abide by or adhere to principles established by decisions in earlier cases.

In the United States and England, the Common Law has traditionally adhered to the precedents of earlier cases as sources of law. This principle, known as stare decisis, distinguishes the common law from civil-law systems, which give great weight to codes of laws and the opinions of scholars explaining them. Under stare decisis, once a court has answered a question, the same question in other cases must elicit the same response from the same court or lower courts in that jurisdiction.

Despite mountains of scholarly research, enough books to fill a library shelf and decades of political battles about gun control, the Supreme Court will have an opportunity this week that is almost unique for a modern court when it examines whether the District's handgun ban violates the Second Amendment.

The nine justices, none of whom has ever ruled directly on the amendment's meaning, will consider a part of the Bill of Rights that has existed without a definitive interpretation for more than 200 years.

"This may be one of the only cases in our lifetime when the Supreme Court is going to be interpreting the meaning of an important provision of the Constitution unencumbered by precedent,'' said Randy E. Barnett, a constitutional scholar at the Georgetown University Law Center. "And that's why there's so much discussion on the original meaning of the Second Amendment.''
