I agree with the Replies.
Frivolous and vexatious appeals are common. Frivolous judgments are commoner.
Pending cases won't decrease if the number of courts is increased. If judges are sincere, there won't be any pendency.
But we shouldn't expect sincerity from judges alone. A majority of people should be honest. Even a minority of people aren't honest.
How can a judge survive without bribing others? Even if God comes down and say that He is God, every official will demand bribe from Him. If a wife wants to spend an hour with her husband, the husband demands bribe. How can judges be an exception? Shouldn't their sons and daughters get jobs?
Frivolous Appeals can be dismissed summarily. But it is rare.
Genuine Appeals are not even taken on file which is highly illegal. But it is quite common.
