altering the essential nature of the thing changed (see Ashok Service Centre versus State of Orissa, (1983) 2 SCC 82). In other words, we have to read the CCS (Pension) Rules, 1972, including Rule 3(g) in the context that IRAI is an autonomous organization registered under the Societies Registration Act. Nevertheless, for examining the application of Rule 3(g) we would enquire into and examine the source of funds of IARI and the Ministry of Agriculture. IARI is entirely dependent on and wholly funded by the Ministry of Agriculture. IARI does not carry out any commercial or business activities as such. IARI though a Central autonomous body, for its funds, has to rely upon and is dependent on the Ministry of Agriculture. Source of funds is thus same and identical. 11. Read in this manner, we do not think that it would be correct to state that the respondent was on foreign service while working on deputation in the Ministry of Agriculture from 19th March, 2007 till he was repatriated to his parent department on 17th December, 2007. We may record that the respondent vide order dated 3rd September, 2007, was promoted to the post of Administrative Officer in IARI, which carried the pay scale of Rs.10,000-15,200. This order was partly modified and he was granted proforma promotion with effect from 9th October, 2007 i.e. the date his junior had joined the post of Administrative Officer, since at that time the respondent was on deputation. The aforesaid dates are relevant and would show that if the parent department i.e. IARI had not agreed to lend the respondent to the Ministry of Agriculture, he would have been promoted to the post of Administrative Officer on 3rd September, 2007. The said post carries the pay scale of Rs.10,000-15,200.
