Two individuals and a number of states lack standing to challenge the minimum essential coverage provision of Obamacare because Congress eliminated the penalty for non-compliance with the statutory requirement of minimum coverage.  As there was no longer any governmental compulsion to obtain the coverage, the individual plaintiffs could not show that their supposed injury from having paid for coverage was traceable to the mere fact that an unenforceable statute required that coverage.  The states, too, could  not show that the unenforceable statute would cause more individuals to enroll in programs that cost the states money.  The other harms the states claimed were not traceable to the unenforceable statutory requirement of minimum coverage.
