Pay Protection after technical resignation

Hello sir.. I rendered my service in PB-1 Rs.5200-20200 + GP 2800 in Delhi high court wef 6.5.13 to 25.2.14. Thereafter joined MES as a clerk in PB-1 Rs. 5200-20200+GP Rs.1900 after technical resignation. My previous govt service has been counted by the competent authority. Now, i put up my case to paying authority for protection of pay Rs.8560 as drawn in Delhi high court + GP Rs.1900 of current post. As per telephonic discussion paying authority told me verbally that pay protection may not be allowed as you didn't complete 1 year probation in high court. Written reply is still awaited from there. Sir, my que is, pls suggest me whether pay protection would be applicable in my case or not. If any rule or office memorandum is available in my case pls help me sir. Am i eligible for protection of pay as Rs.8560 + GP 1900 or not. What should i take next step. Pls guide me sir. Rgds Ritesh 9752178179
