The ONGC however, shall be at liberty to get the price for that period and subsequent period fixed according to the reasonable and rational norms and for that purpose it is open to the ONGC to follow any one of the following three courses: (i) They may request the Central Government to appoint a Commission for the purpose of deciding the prices of gas from time to time, including the time for which we have set aside their demand of price, invoking the provisions of the Commission of Inquiry Act or any other law; (ii) They may invoke the arbitration of some eminent econo mist in consultation with the petitioners; or (iii) They may themselves decide the price, after bringing to their consideration all relevant factors and for that purpose they may hear fully and effectively the petitioners and other persons likely to be affected thereby: If the last of the above three courses is adopted by the ONGC for deciding the price structure afresh, it would be in their interest to give hearing to the persons likely to be affected so that the possibility of a new round of litiga tion is avoided.
