I had heard nothing about this lawsuit.
“Diane Cohen is senior attorney at the Goldwater Institute and lead counsel in Coons v. Geithner, a lawsuit challenging the constitutionality of IPAB.”
Neither had I.
Looks like it also takes another angle: coerced medical coverage with a plan that divulges all medical records to the government as a violation of medical privacy.
