The Supreme Court ruling affects the feds, but does it affect the states as South Dakota has already implemented Obamacare:
Variations in the way states have moved to implement the 2010 federal health-care law have taken on greater significance after last week’s Supreme Court hearings, whose tone heightened speculation that the statute would be overturned.
With the exception of Arizona, all of the states and the District of Columbia have amended their health insurance rules or practices to comply with mandates imposed by the law.
South Dakota lawmakers went a step further, including what one state official dubbed a “suicide clause” that automatically repeals the state law if the entire federal law is found unconstitutional.
But the practical effect of this provision could be limited, at best. That’s because South Dakota’s director of insurance issued state regulations implementing the federal provisions. These remain in force unless and until they are specifically revoked by either the director or the legislature.
