pocket rescission - Supposedly 'created' by the ICA (impoundment control act), due to wording that appears to authorize a recission without Congressional approval if certain filing request and fund expiration date interaction occur.
Basically it is the long wanted (by Presidents) 'line item veto' power being handed to the President.
My opinion on reading the OMB and GAO 'opinions' on the subject:
The Supreme Court will ultimately throw this out as UNCONSTITUTIONAL, being nothing more than a 'line item veto' with skimpy clothing, for which the Constitution DOES NOT provide.
The lower courts will almost certainly throw it out immediately, the Supremes will take a whole lot longer to make their ruling.
Ya want it ? CHANGE THE CONSTITUTION.
