Restoring the courts' proper role in dealing with federal agencies

In America, we have a simple system to resolve legal disputes that seems so natural we almost take it for granted. When a person has a problem with the law, she goes to court where a judge and perhaps a jury are tasked to impartially apply the law to her situation and determine an outcome. It’s not a perfect system, but it has worked for centuries.

What would be ridiculous is if a person has a problem with the law, goes to court, and finds the very officer who arrested her sitting as judge and jury. There is such an obvious conflict of interest that any American would recognize this situation as unjust.
