Just because an ALJ has a certain approval rating doesn't mean that they are unfair.

If an ALJ approves 15% of the cases that came before him, does that mean that those cases were approved unfairly?

What if you were one of those 15% cases that gets approved? Is that unfair?

And what if you were assigned to an ALJ with a 97% approval rating and got denied by that ALJ? Would you still claim the ALJ was unfair?

No governmental system is perfect but be glad that you have had the opportunity for appeals. What if the system was setup in a manner where the initial decision was the ONLY chance one had to present their claim for benefits? What if that was the end of it completely? Just DENIED, end of discussion.

Sure, mistakes "can" be made and some people are denied that may be eligible and some approved that may not be deserving but the system at least gives someone several opportunities to show their eligibility for benefit approval.

Denials are not based on whim. The ALJ states the reasons for denial. Focus on correcting the areas in which you have failed to prove your case, not on your anger at the system.
