you don't know what you are talking about. the rules can always be changed over time and:
"It is a central principle of law: Courts are supposed to follow earlier decisions – precedent – to resolve current disputes. But it’s inevitable that sometimes, the precedent has to go, and a court has to overrule another court, or even its own decision from an earlier case."
That case is just one rule from one judge, which could be right or wrong by itself. It could have been challenged in supreme court if the us-china deal haven't been made.
There is value in observing legal precedent, but sometimes circumstances, logic or judges’ views determine it’s time to overturn it.
