Labor appeal

My employer has filed an appeal to the Dubai Court decision on our labor case where they did not show up by submitting a backdated termination letter showing termination before the filing of the labor case.

I have the pic of actual termination letter which I was asked to sign after the labor case. 

Actual timeline 21-07-2015 labor case filed, 27-07-2015 I was asked to sign termination which I didn't backdate, the document shows 18-07-2015 before the labor complaint.
