Noun vs law school nans gives nigerian government ultimatum

I think there may be a bit of confusion here!

It seems like you've provided a series of unrelated words and phrases. Let me try to help you make sense of it:

If I had to make sense of this, I'd say that someone or something (perhaps a group or organization) is giving the Nigerian government an ultimatum, but I'm not sure what the context or reason for this ultimatum is. Could you provide more information or clarify what you mean by "Nans" and the relationship between the noun and law school?
