We often close questions with the reason
"Questions seeking advice on company-specific regulations, agreements, or policies should be directed to your manager or HR department. Questions that address only a specific company or position are of limited use to future visitors. Questions seeking legal advice should be directed to legal professionals.

But there is problem with this -- since the heart of the employer-employee relationship is a legal contract, and every company is different, this close reason can be applied to all questions.
In the case of Can I be sued for leaving with proper notice in the UK?, the OP is asking a fairly general legal question, with wide applicability to readers of Workplace. The answer is something that all responsible employees would want to know. "If I comply with the notice requirements of my jurisdiction [country, province, etc.], can I have any additional liability?"
After reading the Workplace for a couple of years, I still don't understand why some questions get closed with this reason. Furthermore, by combining two reasons into an omnibus close, it makes it even more confusing.
Can we improve question closing by splitting up this "reason" into its two unrelated reasons?
Can we separate general legal questions from the more specific ones that are not useful to readers in the future?
After reflecting on my question, I suspect that there is a difference in perspective between those who work in at-will jurisdictions and those who don't. When reviewing related meta-questions, I can see a pattern. If a person seems to work in a at-will jurisdiction, they are much more likely to favour a strict interpretation of this rule. Legally, it is simpler there - all one has to say is "You're fired" or "I quit". Where I work, if I quit with no notice, I can be sued, even without a contract document. When I quit my job at McDonalds at age 19, I didn't have to hire a lawyer to determine how much notice to provide - I just relied on the "common knowledge" about the provincial labour code on required notice.
All workplaces are governed by labour regulations and the contractual obligations of its participants, which make all Workplace questions legal questions, ultimately.
