Promotion

I was working in a Kerala Govt. owned Public sector Undertaking from 2000 to 2006 on contract basis and in 2007 Govt of Kerala absorbed me as a permanent staff. Next Govt terminated my service as back door appointment. I filed a case in the single bench Hon. High Court of Kerala and got a Judgment in 2009, court ordered reinstate me with back date i.e., date of termination without any monetary benefits . Govt of Kerala filed appeal against this Judgment before the division bench and appeal dismissed by the court and I reinstate the service in 2012. But my service calculation for promotion company not considered my 4 and half years spent out of service ( from 2007 to 2012). Again approached to single bench of Hon. High Court of Kerala and court ordered to give me 4 and half years. Govt of Kerala filed appeal against this Judgment before the division bench and court dismissed appeal. Now Govt of Kerala filed appeal before the Hon. Supreme court of India, now case pending for admission , I want advice whether I appoint advocate this stage? Or after getting admission only ? Almost all advocates says court will not give admission it will automatically dismissed the case because single bench as well as division bench of Kerala High Court judgment was favor to me. If I appoint advocate in this admission stage can I defend for giving admission? I do not know the procedure of Supreme Court, pls give me advice
