For a people who are free, and who mean to remain so, a well-organized and armed militia is their best security.
In 1972, the Supreme Court of the United States decided Roe v Wade 410 US 113 (1973) (Findlaw | Justicia | Oyez | wikipedia), which held the Due Process Clause of the Fourteenth Amendment to the US Constitution protects the (penumbral) right to privacy, including a woman’s qualified right to terminate her pregnancy. It was a controversial decision which demonstrated that the Court was at the vanguard of the dominant public political mood. The Court was sharply divided; the case was decided on the basis of contestable constitutional theory; and it has subsequently given rise to a huge amount of analysis and scholarship, as well as much partisan social commentary and political scheming.
In 2008, the Supreme Court of the United States decided US v Heller 554 US __ (2008) (official pdf | Findlaw report) (Balkinization | Mike O’Shea on Concurring Opinions | NRA | Posner | ScotusWiki | Volokh | Wikipedia), which held that the Second Amendment to the US Constitution protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home. As with Roe, it, too, was a controversial decision which demonstrated that the Court was at the vanguard of the dominant public political mood. Again, the Court was sharply divided; the case was decided on the basis of contestable constitutional theory; and it has already given rise to a huge amount of analysis and scholarship, as well as much partisan social commentary and political scheming.
But there is one obvious difference between the two cases: whereas Roe stands as the highpoint of liberal judicial activism and reflects a then quite dominant liberal political perspective, Heller stands as a similar highpoint of conservative judicial activism and reflects a now very marked conservative political perspective.
These similarities and differences raise some important questions. For example, Roe became a rallying-point for legal, social and political opposition (update: backlash) to judicial and political liberalism; will Heller become a similar rallying-point for legal, social and political opposition to judicial and political conservatism? Moreover, views on the correctness of Roe have become a litmus test for Republican nominees to the Court; will Heller similarly become a litmus test for Democratic nominees to the Court?
Finally, if (and when?) there is a majority on the Court to reverse Roe, will they do it? Or will they baulk at such a naked exercise of judicial-political power? Or are there other judicial/political considerations afoot? Or will they realise that to overrule Roe simply because they disagree with its political underpinning would be to eviscerate the doctrine of precedent? If they do overrule Roe, then every decision of the Court is up for grabs, even the case that overrules Roe, and yes, even Heller!
