You cannot opt for larger / single bench, it is as per roaster of the High Court decided by Chief Justice.

In most Indian High Courts, a division bench acts as the appellate authority for decisions made by a single judge. 

When filing an appeal to the division bench, you need to demonstrate that the single judge made a legal error in their decision or that the decision was based on incorrect facts. 

if a single bench dismisses an application, you can file an appeal, which is often called a "Letters Patent Appeal" (LPA), before a division bench of the High Court to challenge the single bench's decision; essentially, you can file an application before the division bench seeking a review of the single bench's order.

Fresh petition  could be filed if there is a fresh cause of action or a change in circumstance; the single judge's order is appealable if the order is erroneous on substantial grounds.
