Withdrawal from registration as a broker-dealer, agent, investment adviser, or investment adviser representative becomes effective 90 days after receipt of an application to withdraw or within any shorter period of time which the Commissioner determines, unless: A revocation or suspension proceeding is pending when the application is filed; or A proceeding to revoke, suspend, or impose conditions on the withdrawal is instituted within 90 days after the application is filed. If a proceeding is pending or instituted, withdrawal becomes effective at the time and on the conditions the Commissioner by order determines. If no proceeding is pending or instituted and withdrawal automatically becomes effective, the Commissioner nevertheless may institute a revocation or suspension proceeding under § 11-412(a)(2) of this subtitle within 2 years after withdrawal became effective and enter a revocation or suspension order as of the last date on which registration was effective.
