How to defend the labour case in appeal after winning the first instance decision

Dear Lawyers,

I would like to bring to your kind attention that a month back I have won a case against my employer of AED 120,000. After 10 days of the first instance decision, my employer had filed an appeal.

In the appeal, he has mentioned that he was not given a fair chance to explain the appointed expert. He wants to reopen the case and refer it to the same expert and explain to him all the important points which he missed.

The court has given the first hearing date of appeal. My question is that can the judge dismiss his appeal after the first hearing as his appeal is based on some ridiculous charges on me?

I would like to avail your respective services to handle this appeal. Please advise how much will be your charges for the above-mentioned issue.

Looking forward to hearing from you guys soon.

Regards.
