§ If at any time after the expiration of five years from the commencement of this Act it appears to the Board of Trade that the unemployment fund is insufficient or more than sufficient to discharge the liabilities imposed upon the fund under this Part of this Act, or that the rates of contribution are excessive or deficient as respects any particular insured trade, or any paticular branch of any such trade, the Board may, with the sanction of the Treasury, by special order made in manner hereinafter provided revise the rates of contribution of employers and workmen under this Part of this Act, and any such order may, if the Board think fit, prescribe different rates of contribution for different insured trades or branches thereof, and where any such order is made the rates prescribed by the order shall as from such date as may be specified in the order be substituted as as respects trades or branches thereof to which it relates for the rates prescribed by this Act:
§ Provided that where such a revision has been made no further revision under this Section shall be made before the expiration of five years from the last revision, and that no order under this Section shall increase the rates of contribution from employers or workmen by more than one penny per workman per week above the rates specified in the Eighth Schedule to this Act, or shall vary such rates unequally as between employers and workmen.
§ Amendments made: Leave out the word "five" ["expiration of five years from the commencement"], and insert instead thereof the word "seven."
§ Leave out the word "five," and insert instead thereof the word "seven" ["five years from the last revision"].—[Mr. Buxton.]
