does not appeal to us and we are inclined to agree with the findings of the Tribunal and the Delhi High Court that the classification is discriminatory and unreasonable since doctors under both segments are performing the same function of treating and healing their patients. The only difference is that AYUSH doctors are using indigenous systems of medicine like Ayurveda, Unani, etc. and CHS doctors are using Allopathy for tending to their patients. In our understanding, the mode of treatment by itself under the prevalent scheme of things, does not qualify as an intelligible differentia. Therefore, such unreasonable classification and discrimination based on it would surely be inconsistent with Article 14 of the Constitution. The order of AYUSH Ministry dated 24.11.2017 extending the age of superannuation to 65 Years also endorses such a view. This extension is in tune with the notification of Ministry of Health and Family Welfare dated 31.05.2016. 23. The doctors, both under AYUSH and CHS, render service to patients and on this core aspect, there is nothing to distinguish them. Therefore, no rational justification is seen for having different dates for bestowing the benefit of extended age of superannuation to these two categories of doctors. Hence, the order of AYUSH Ministry (F. No. D.14019/4/2016EI (AYUSH)) dated 24.11.2017 must be retrospectively applied from 31.05.2016 to all concerned respondent doctors, in the present appeals. All consequences must follow from this conclusion.”
