Under Section 35, the Central Government's power to remove difficulties by order must be exercised within _____, and every such order must be _____.

Section 35(1) empowers the Central Government to remove difficulties arising in giving effect to the Act by order published in the Official Gazette, provided the order is not inconsistent with the Act's provisions. The proviso to Section 35(1) mandates that no such order shall be made after the expiry of three years from the commencement of the Act. Section 35(2) requires that every such order shall, as soon as may be after it is made, be laid before each House of Parliament. This parliamentary laying requirement ensures legislative oversight and prevents the Central Government from making open-ended modifications, maintaining Parliament's supremacy in shaping the law.
