Behind all the rhetoric over the health care law lies a constitutional debate over authority.
One of the key objections for most Republican lawmakers against the Patient Protection and Affordable Care Act, signed into law last year by President Obama, is what's called the individual mandate — a provision that will require most Americans to become insured by 2014.
Many Republicans, including Rep. Dan Lungren of California, believe Congress doesn't have the constitutional authority to make people buy insurance, and they object to the idea that everyone must have it.
But as constitutional law expert Andrew Koppelman tells Weekend All Things Considered host Guy Raz, Congress can trace its constitutional authority to mandate health care coverage to the Constitution's "necessary and proper clause."
The Commerce Clause
The idea behind the individual mandate is that as more individuals enter the marketplace for health insurance, competition will grow and the price for getting coverage will go down.
But does Congress have the power to help expand the marketplace by compelling citizens to buy insurance?
Lungren argues that citizens have the right to not to buy health insurance, and that Congress is overstepping its authority in compelling individuals to choose either to comply or face a penalty on their income taxes.
He says that the Constitution's "commerce clause" does not enable Congress to mandate individuals to buy health insurance. He questions the notion that "if you refuse to enter interstate commerce — that is, if you consciously decide to be inactive — that in and of itself is a type of interstate commerce," and that Congress has the power to penalize citizens without coverage.
The Necessary And Proper Clause
Koppelman, who teaches law at Northwestern University, says that the Constitution's "necessary and proper clause" cannot be factored out of this debate.
"When somebody goes without health insurance, we can argue about whether they are or are not part of interstate commerce, but it doesn't matter," Koppelman says.
Koppelman says that in order to carry out its responsibilities, Congress can enact policies that are not among its enumerated powers in the Constitution.
A Slippery Slope?
A common criticism of the individual mandate is that the provision establishes a precedent of overextending the authority of the legislative branch.
"It's an extraordinary reach once you start to analyze what you are actually talking about," Lungren says.
Koppelman acknowledges that Congress could abuse its authority, but he also emphasizes that it is "quite unusual for Congress to require people to do something."
"The idea that we are on a slippery slope to Congress forcing you to do all kinds of things you don't want to do just misunderstands political reality," Koppelman says. Copyright 2011 National Public Radio. To see more, visit http://www.npr.org/.
