Immunity from prosecution may be granted for cooperative full disclosure, but can be withdrawn for non compliance or concealment. Section 32K permits the Settlement Commission to grant immunity from prosecution and, subject to conditions, from penalty and fine to applicants under section 32E who cooperate and make full and true disclosure; immunity cannot be granted if prosecution had been instituted before the application. Immunity is withdrawn for failure to pay or comply with conditions or for concealment or false evidence, after which prosecution and penalties may proceed; the section's powers will be exercised by the Interim Board mutatis mutandis.
