Regulatory directions can require refunds, restrict market access, or suspend trading to protect securities investors under the law. The Board may direct originators or persons associated with securitisation to refund monies (with or without interest), restrict such persons from accessing the capital market or engaging in securitisation or regulated activities for a specified period, and direct recognised stock exchanges to refuse or suspend trading in securitised debt instruments; the Board may impose other fit directions and must ordinarily give a reasonable opportunity of being heard, although interim directions may be issued with a post decisional hearing.
