Reply #3: This is a rather complicated area of law

[Alcibiades]

Lawyers? Hello?

It's not a question of sovereign immunity, because that does not apply to county government and is specifically exempted in civil rights cases in any event. From what I read of the article, I think that the feds were able to issue subpoenas for that, but they want some financial information that is apparently not covered under the statute.

I'm probably wrong: I'm a political scientist, not a lawyer, and this is a rather complicated question of law. That the state thinks it has the power, but the DoJ does not, may also mean this requires an understanding of Arizona law.
