Immunity from prosecution and penalty may be granted by the Settlement Commission if applicant cooperates, subject to conditions. The Settlement Commission may grant immunity from prosecution and wholly or partly from penalties to an applicant who cooperates and makes a full and true disclosure, subject to conditions and excluding cases where prosecution began before the settlement application. Immunity is withdrawn for failure to pay sums or comply with conditions in the settlement order or if the applicant concealed material or gave false evidence, after which prosecution and penalties may follow as if immunity had not been granted.
