Many of those questions are along the lines of "Was this a good decision, or a biased decision?" To be blunt, these questions are inappropriate for every Stack Exchange site, with the possible exception of MSE and site metas. Evaluating whether a decision was due to bias or not is not a question that has a correct answer; we can't tell what someone was thinking when they wrote a decision, because that would require reading their mind. Evaluating if a decision was just is entirely opinion-based; I don't know what sort of objective answer you'd be looking for there.
Almost all the questions you linked were of that sort: was this decision good or bad, or just or unjust, or biased or unbiased. This question is simply not one with an objective answer. Your questions like "what are some decisions regarded as wrongly-decided" might be better, but it's a list question, and list questions aren't allowed on any SE site. Your question on how to evaluate quality of decisions presupposed that "quality of decisions" is an objective concept; it's not. Asking about who is more skilled likewise has no objective answer; "skill" is an extremely ill-defined concept if you want objectivity, and "who's a better lawyer" is pretty much one of the most pure opinion-based questions there is. Asking about outcomes has measurable aspects; asking about skill (without some objective measure you give) does not.
Basically, many of your questions ask to evaluate a court decision. We can't do that. That requires discussion; this is not a discussion site, and the whole structure of SE sites is designed to resist discussion.
Basically, before asking a question, think this: "If two people post separate answers, and those answers disagree, what does it mean for one to be more correct than the other?" For "Was this decision just," there is no "more correct" or "less correct" one; if a decision was fair or not is just a matter of pure opinion.
