That law was passed in 1999, but was fought by groups like NOW.
It did not become law (because of legal battles) until 2000.
It is my belief that it was easier for the Louisiana Legislature and Governor Bobby Jindal to pass the new law based on the Law for Sanitary Inspection of Abortion Clinics
Of course, that is my personal belief...
Someone in the Louisiana Legislature might have more information, or Brian Clapper with Louisiana Right to Life...
Don’t get me wrong, I totally believe the laws that passed and the legislators and issue groups for these laws, are happily responsible for this clinic being shut down. No question.
