Evicting a tenant

I filed a petition in Munsif Court - Vnb for evicting a tenant on the group of self occupation.  After 2 years of following up, i got the judgement in my favor.  Now the tenant has preferred an appeal against the order.  Now my question is 

1. how long the process of appeal will take.?

2. is there any provision to minimize the duration of process ?

3. if his appeal is rejected, would the tenant  approach higher court ?

thanks in advance for useful information.

thanks / s a.
