Power to remit cases to the proper officer when a settlement applicant fails to co-operate, with evidence reuse and time exclusion. Where the Settlement Commission finds non-co-operation by an applicant it may send the case back to the proper officer who shall dispose of it as if no settlement application had been made; the proper officer may use all materials, information and evidence produced or recorded before the Commission as if produced or recorded before him, and the period from application to receipt of the Commission's send-back order is excluded for statutory time limits and interest calculation.
