To answer the above query, I will need to know a few more facts from you.
1. Was the appointment to the new post on your request?
2. Is the maximum of the pay band in the time scale of the lower post less than your substantive pay in respect of the old post?
If the answer to to Q1 is in affirmative and Q2 in the negative, your case for appeal might not stand very strongly in court. However, if the facts state otherwise, a further deep dive will be possible in the case analysis.
