Very thoughtful piece by David Rose  on consequentialist thinking and the rule of law. An excerpt:
If confirmed, Ms. Kagan may hear a constitutional challenge to the mandatory insurance requirement of the new health-care law.
A nonconsequentialist judge would examine whether the Constitution empowers the federal government to require citizens to purchase a private good (health insurance) and make a ruling on that basis alone.
But a consequentialist judge would look beyond the law and consider the insurance mandate’s impact on society. Using this criterion, the consequentialist judge might see the mandate as a “benefit to public health” and a “compelling state interest.” Such thinking would lead to a loose interpretation of the Commerce Clause and an affirmation of an unprecedented loss of personal liberty in America.
