Confiscation of goods permits a fine in lieu, requires an opportunity to be heard and vests title in the government. Confiscation and penalty apply where goods are supplied, received, unaccounted, supplied without registration, or a conveyance used in contravention of the Act with intent to evade tax; the adjudicating officer may offer a fine in lieu not exceeding market value less tax, subject to aggregate minimums, while owners remain liable for tax, penalty and charges; no order is to be passed without hearing, title vests in Government, and the proper officer may hold and, after a limited period, dispose of confiscated items and deposit proceeds with the Government.
