Reconciliation allows a bill to pass the Senate in a limited time period, with limited amendments, and with only 51 votes; filibusters are not permitted. In 2010, Democrats split their health-policy changes into two bills, one of which they enacted through this fast-track process. In 2013, a Republican majority could use the same reconciliation process to repeal those changes.

The reconciliation process, however, applies only to legislative changes to taxes, spending and debt, or the change must be a “necessary term or condition” of another provision that affects taxes or spending.

Crucial parts of ObamaCare meet this test. Thus, if a President Romney has cohesive and coordinated majorities in the House and Senate, a reconciliation bill could repeal the Affordable Care Act’s Medicaid expansion, insurance premium and drug subsidies, tax increases (all 21 or them), Medicare and Medicaid spending cuts, its long-term care insurance program known as the Class Act, and its Independent Payment Advisory Board, a 15-member central committee with vast powers to control health-care and health markets.

Chief Justice John Roberts ruled that the financial penalty enforcing the individual mandate is within Congress’s constitutional power to “lay and collect Taxes,” and that the mandate and penalty are inextricably linked. This should suffice to enable repeal, through reconciliation, of both the individual and employer mandates, and their respective penalty taxes.
