A key provision of the US health care overhaul engineered by President Obama has been ruled unconstitutional by a US district court judge.

The law required that individuals be compelled to purchase health insurance or face fines.

The entire law has not been invalidated, just this key provision…It will no doubt be appealed and will eventually work its way to the Supreme Court.

The ruling could slow the implementation of the law and perhaps slow the growth of the federal deficit…

US yields are falling further, down to 3.27% at the moment.
