In its 5-4 decision to uphold the U.S. health care law, the Supreme Court answered several key questions:
...
Question: Can the court decide the constitutionality of health care now, or does it have to wait a few years?

The court's answer: The court upheld the entire law.

Question: Is the requirement that people have health insurance - the so-called individual mandate - constitutional?

The court's answer: Chief Justice John Roberts wrote that the commerce clause did not apply, but the mandate stands under the taxing clause.

Question: If the individual mandate is unconstitutional, can the rest of the law stand, or is the whole thing unconstitutional?

The court's answer: The mandate is constitutional, rendering moot further questions on the rest of the law.

Question: Can the federal government force states to expand their share of Medicaid costs and administration?

The court's answer: Yes, but the justices ruled that the federal government cannot remove existing Medicaid funding if the states choose not to participate in the new program.
