One aspect that seems to be overlooked is the fact that they went back to basics with the law rather than use 'stare decisis' or legal precedent [Latin, Let the decision stand.] The policy of courts to abide by or adhere to principles established by decisions in earlier cases. (a doctrine or policy of following rules or principles laid down in previous judicial decisions unless they contravene the ordinary principles of justice).
Basically they decided on the facts and law rather than just following a decision made in another case.
Each and every case should be based on its own merits and facts and not on those of a preceding case.
Incrementally over a long period of time one poor decision gets used as a precedent for another, and then another, and so on.
This is an infiltration of the legal system much like the way the education and health systems have been infiltrated.
