Jewellery recognition conditions require retention, inspection and permit retrospective withdrawal making wealth-tax payable for prior assessment years. The amendment narrows the official-residence exemption to buildings declared as such immediately before the Twenty-sixth Amendment, effective 28 December 1971, and adds provisos to clause (xiv) conditioning government recognition of jewellery on permanent retention in India (except Board-approved temporary removals), preservation of original shape, and allowing official inspection. The Board may withdraw recognition retrospectively for failure to comply, causing wealth-tax to be payable for affected assessment years; the fair market value at withdrawal is deemed to apply to successive valuation dates, and aggregate tax liability under withdrawal is capped at fifty per cent of that fair market value.
