Dear Amit, appeal is never against anybody, neither against individual nor the Govt. but to prove innocence. So admission of your appeal prima facie indicates your innocence. However police also will submit the same that your case is under appeal in the HC. Now it's the department to decide to allow you joining or wait for the outcome of the appeal. But, sorry dear, I will not give you false hope, 90% you will not be allowed to join. However don't bother about it, let the offer of appointment order come first.
