Republicans can't stop IPAB. But they might slow it down.

Republicans' newest attempt at blocking Obamacare is not another Supreme Court case. It's not a full piece of legislation. Instead, it is a two-line item quietly tucked into a rules bill passed last week (and astutely noticed by the Hill's Sam Baker). The provision, in full, is this: "Independent Payment Advisory Board- Section 1899A(d) of the Social Security Act shall not apply in the One Hundred Thirteenth Congress." Did the House just abolish a health-care board in the swoop of 20 words? Not exactly: What this provision does, essentially, is change the ground rules for debating any cost-cutting recommendations from the Independent Payment Advisory Board, or IPAB.
