We act on decisions made by government agencies, on disputes between parties, and on reaching an outcome without a hearing.
A decision by an agency is reviewed on how it was reached, not on whether somebody else would have reached a different one. That distinction decides most of what is worth doing, and it is the first thing we test.
Most disputes settle. The useful questions are usually when, on what terms, and what it costs to get there — rather than who would win at the end of it.
