While President Obama can be accused of abusing his power in numerous ways, the lawsuit by House Speaker Boehner against the president will focus on unilateral changes he made to the Affordable Care Act.
From a the text of a bill released this afternoon by the House Rules Committee, which authorizes legal action based on . . .
the failure of the President . . . to act in a manner consistent with that official’s duties under the Constitution and laws of the United States with respect to implementation of (including a failure to implement) any provision of the Patient Protection and Affordable Care Act and title I and subtitle B of title II of the Health Care and Education Reconciliation Act of 2010, including any amendment made by such provision.
This would presumably mean changes to deadlines and the waiving of various requirements – like the employer mandate – that Obama has done all by himself.
