It seems that despite the decision to ban the legal tag six years ago, it's still alive and well. The majority of questions that use this tag seem to get closed almost immediately and its continued existence seems to suggest to newcomers that it's okay to ask "is it legal" questions.
Apparently it was removed back then. It came back a bit under three years ago and now has the following wiki excerpt:
Questions involving local labour laws or about working within the legal system such as for the courts or lawyers. Please note that we can not provide case-specific legal advise. Also consider if your question might be more appropriate on https://law.stackexchange.com
The focus of the older meta discussion was on legal advice, which is off-topic here. The current description isn't about that. I don't know the history here (in particular, if there was another meta thread), but I don't think we should delete the current tag based on the old discussion. (I'm not saying we shouldn't delete it after having a new discussion based on the current definition; I don't yet have an opinion on that.)
I agree with Monica's answer, we should not necessarily remove it.
The tag now clearly refers to work-related questions on legal workplaces (courts, etc.). This could be easily answered by, say, any user with working experience on such places.
I think however, that it has been misused by recent questions, where they include it using the "old" concept of the tag instead.
What I think we can do is to rename it to something like legal-industry instead. This would help remove the possible confusion here, as it will now be clearer that it does not refer to legal questions, but rather questions about legal work environment (courts, law firms, etc.).
This way would also be aligned with current ""tag standards" given the other
x-industry tags we have in the site (like our top 3 tag software-industry).
How about creating two tags: laws and legal-industry? It doesn't sound appropriate to bundle those together into a single tag, since laws apply to all workplaces, not just those in the legal industry.
laws can be used for questions concerning laws applicable to the workplace, and ones which the legal department of a company (or even HR in some cases) can reasonably be expected to answer (example: "What is the minimum daily wage according to the Elbonian law?")
legal-industry can be used for questions about a workplace pertaining to the legal industry, such as courts and law firms.
Analogously, it isn't appropriate to subsume software into software-industry. For example, a mom-and-pop pizza shop may be using a software to generate invoices, track inventory, etc.. A question pertaining to the software use (example: "How do we manage a software upgrade without shutting down our business for a month? :)") cannot put a pizza shop into the software industry.
