Opening New GPF Account

I was a regular permanent employee of government of Karnataka, appointed in the department of Animal Husbandry on 23-03-1992. I was having GPF account No. VET-8500 allotted in the department, allotted by AG of Karnataka. I have served in the department there for about more than twenty years and later on i have applied for the post of Asst. Professor in Karnataka Veterinary University ( an autonomous body ) in 2012 through proper channel and after selection i have taken permission from the dept.of Animal Husbandry and got relieved from the dept. and joined University after 01-04-2006, the date from which, Karnataka govt. has implemented New pension scheme . So for those who have joined government service after 01-04-2006 , they are covered under new contributory pension scheme and there is on GPF provision for them. On the similar lines, saying that i am not “a transferred employee , retrenched employee or candidate appointment by the department”. University registrar have denied my application of request for allotting me a new GPF account in the university, because they are treating me as new employee recruited after 01-04-2006. So with this background am i eligible for opening GPF account in the University. Please give me some clarification so that i can challenge this in the court of law.
Thanking you sir Sincerely yours
