JUDGMENT : 1. The petitioners have filed the present petition, inter alia, impugning the recommendations of an Expert Committee (as communicated by a letter dated 27.12.2017) constituted by Government of India under the chairmanship of Dr. Girish Sahani, Director General CSIR (hereafter referred to as ‘the Third Committee’) to, inter alia, examine and assess whether Transcutol P can be permitted for human use in parenteral formulations. The petitioners also impugn the communications dated 04.07.2018 and 09.07.2018 sent by respondent no. 5 (Drugs Controller General of India – DCGI) to Drug Licensing Authorities of the State of Uttarakhand and the Union territory of Daman and Diu to cancel the petitioner’s licenses to manufacture Diclofenac Sodium Injection 75 mg/ml containing Transcutol P (hereafter “the drug in question”). The said communications were sent by DCGI on the basis of the letter dated 27.12.2017, issued by the Chairman of the Third Expert Committee and minutes of the meeting dated 20.12.2017 of the Third Expert Committee. 2. The petitioner in W.P. 7073 of 2018 (M/s Themis Medicare Limited – hereafter “the petitioner”) is a pharmaceutical company which manufactures the drug in question – Diclofenac Sodium 75 mg/ml Injection – containing Transcutol P as an excipient under various brand names. Diclofenac Sodium injection 75 mg/ml is marketed by M/s Novartis India Limited (hereafter “Novartis”) under the brand name “Voveran 1ml”. The petitioner’s patent for its injection is pending in India. 3. The petitioner in W.P. 8672 of 2018 (M/s Gattefosse, France – hereafter “Gattefosse”) manufactures the Transcutol P used by the petitioner. Gattefosse is the sole manufacturer and supplier of Transcutol P for parenteral purposes. 4. The Third Committee had recommended that Transcutol P as an excipient in parenteral formulations, needs to be tested for its toxicity independently in order to establish its safety as it found no evidence that the same could be used in parenteral formulations. The petitioners dispute the same and contend that there is sufficient material to establish that use of Transcutol P in parenteral form is safe. This is the principal controversy involved in these petitions. Factual Background 5. Respondent no. 8 (M/s Troikaa Pharaceutical Ltd. – hereafter “Troikaa”) applied to DGCI for approval of the drug in question containing Glycurol as an excipient as a “new drug” under Rule 122E of the Drugs and Cosmetic Rules (hereafter ‘the Rules’). This is the principal controversy involved in these petitions. Factual Background 5. Respondent no. 8 (M/s Troikaa Pharaceutical Ltd. – hereafter “Troikaa”) applied to DGCI for approval of the drug in question containing Glycurol as an excipient as a “new drug” under Rule 122E of the Drugs and Cosmetic Rules (hereafter ‘the Rules’). On 30.07.2007, DCGA approved the drug in question as a new drug under Rule 122E of the Rules. On the basis of the said approval, on 17.08.2013, the petitioner applied for and was also granted License to manufacture the drug in question by the Drugs Licensing Authority, Daman and Diu. The petitioner was, thereafter, granted license to manufacture the drug in question by the Drugs Licensing and Controlling Authority, Uttarakhand on 04.04.2016. 6. In June 2013, the petitioner started manufacturing the drug in question. Pursuant to this, the petitioner also entered into an agreement with Novartis for selling the aforesaid formulation under the brand name ‘Voveran 1 ml’. 7. The petitioner claims that the petitioner and Novartis gained the leadership position in the market which led to the decline of the market share of one of the competitors, Troikaa. The petitioner further claims that due to the decline in market share, Troikaa manipulated and misled various State and Central Agencies against the petitioner regarding use of Transcutol in parenteral preparations. 8. In November, 2015, DCGI received complaints from doctors against the petitioner’s formulation. The petitioner claims that the above-mentioned complaints were motivated and at the instance of Troikaa. 9. The petitioner received a letter dated 04.09.2015 from the Joint Drug Controller, CDSCO (DCGI), asking the petitioner to submit a clarification regarding the use of Transcutol in the Diclofenac Sodium Injection and the details of the excipients used in the formulation of the Diclofenac Sodium injection. 10. The petitioner claims that on 22.09.2015 it submitted eleven studies – studies on Transcutol, repeated dose toxicity studies and single dose studies – in response to the letter received from DCGI. On 09.11.2015, the petitioner submitted additional data to DCGI with reference to the same. 11. The petitioner received a communication dated 10.12.2015 from the SND Division of DCGI to attend a meeting scheduled on 18.12.2015 of an Expert Committee formed by DCGI (hereafter “First Expert Committee”) to review the safety and permissibility of “Diethylene Glycol Monoethyl E
