This reminds me of how both legislatures and courts can be extremely hesitant to set down clear rules, even (in my view) when it would be in the public's best interest to do so.
In Nevada, the State Constitution bars members of the executive branch from holding seats in the Legislature. However, people have argued for decades as to whether this encompasses all public sector employees (extending to university professors and cops), or whether this just applies to high-level employees like people appointed by the governor.
Many lawsuits have been filed over this issue. Frustratingly, every time the State Supreme Court has taken on the issue, it has opted to issue narrow procedural rulings (e.g. dismissing or remanding cases on technicalities) instead of handing down a rule.
There is still a pending case before the State Supreme Court on this issue. Meanwhile, public employees serving in the Legislature are left in the dark as to whether their service is legal, which is bad for them, candidates who run against them, and their constituents.
