There is no ambiguity in the wording or the purport of sub-clause (ix). It is first declared that for the purpose of calculation of outstanding licence fee upto 31.7.1999, the effective date of the licensee's will be notionally extended by a period of 6 months. However, where more than six months extension of the effective date has already been given, "due to whatever reasons" further extension of effective date by further a period of 6 months will not be given. In the cases of eligible licensees, the period of extension already given will be deducted from the notional extension of six months given under sub-clause (ix) so that the total extension of period does not exceed 6 months. It has clearly been stated in sub-clause (ix) that "in cases where extension of period of more than 6 months has already been given, there will be no further change". In case of Bharti, extension of effective date from 28.2.1997 to 30.9.1997 has already been given , which means it has enjoyed the benefit of an extended period of 7 months. Sub-clause (ix) does not in any way permit Bharti to enjoy any further extension of 6 months for fixation of its effective date.
