Amendment in the nature of a substitute sought to prohibit Federal revenues from growing faster than the rate of increase in national income in the second prior fiscal year, unless a three-fifths majority of both the House and Senate vote to approve a specific tax increase authorizing a higher rate of revenues. \ This amendment was subsequently agreed to by a vote of the full House pursuant to clause 2(d) of rule 23 which provides, that in the Committee of the Whole, when the votes of the Delegates and Resident Commissioner are decisive, the vote must be retaken. See Roll Call No. 63.
