Inservice phd

Respected all , iam ,dr.p.vidya sagar, assistant professor, dpt.of surgery and radiology , joined in the sri venkateswara veterinary university , tirupati, andhra pradesh in 2012. in general, university offers insevice phd on deputation after completion of probation in the same university for the assistant professors. half of the candidates got phd deputation who were recruited through 2012 and 2013 recruitment. From the academic year 2017-18, the SVVU had abolished the system of deputation of ins-service Assistant Professors within University. In our country, now there are 16 veterinary Universities of which this is the only Veterinary University which had taken such decision, while all other Universities are deputing own faculty for PhD programme within same University. In Andhra Pradesh SVVU had been carved out of ANGRAU in the year 2005-06 and all the administrative and policy procedures are adapted from ANGRAU. The undivided ANGRAU (of 2004) is now made into 6 Universities of which none of the remaining 5 universities had adapted such policy of abolishing internal deputation for PhD programme. The time of decision to abolish internal deputations is making some candidates as less privileged among equals. and effects the future prmotion. higher authorities denied our representation to restore the inservice phd programme and advised go on external deputation to other universities out side andhra pradesh.for which we loose 3 yrs of service which is not considered for further promotions. please advise me , in this regard can i proceed legally
