Commencement date change for black money law advances operation of declaration and tax chargeability provisions. The Order substitutes the Act's stated commencement date with an earlier date by amending the commencement clause, clarifying that the declaration mechanism for undisclosed foreign assets, the valuation date for declared assets, and the chargeability rules operate from that substituted commencement date to remove interpretive difficulty about the meaning of 'date of commencement of the Act'.
