Issuance of show cause notices against EOUs depends on the Development Commissioner's determination of export obligation within the prescribed timeframe. Issuance of show cause notices against EOUs is proper for clear violations like illicit removal; however, alleged non fulfillment of export obligations should be proceeded with only after consultation with, and ordinarily the decision of, the Development Commissioner or Director STPI. After a five year block the DC/Director STPI should decide fulfillment of export obligation within six months, and at the latest within one year, and duty may be demanded in accordance with that determination.
