Penalty imposition: Board may impose and quantify penalties considering gain, investor loss and repetitive defaults. The Board or the adjudicating officer may impose penalties by written order if satisfied of liability under the relevant provisions; in fixing quantum the authority must consider disproportionate gain, loss to investors, and repetitive defaults. Orders must identify the statutory provisions breached, give brief reasons, and be dated and signed. The authority may rectify errors apparent on the face of the record-limited to typographical or plainly detectable mistakes-on its own motion or at the request of the affected person within the prescribed short period.
