Leaving aside that you use Wikipedia as a source, if you read what you cited closely you'll see those state laws had to do with state cooperation in enforcement of federal law.
That's distinguished from the situation in the article in the original post, which says the Kansas law would prosecute federal officials from enforcing such laws in Kansas.
Try again.
“if you read what you cited closely you’ll see those state laws had to do with state cooperation in enforcement of federal law.”
Yes this is called nullification.
“That’s distinguished from the situation in the article in the original post, which says the Kansas law would prosecute federal officials from enforcing such laws in Kansas.”
This is called litigation & interposition.
Both are part of of the general process(Spoken of in the Federalist papers), whereas Nullification is simply designed to refuses state support for the unauthorized act and to give legitimacy to resistance. Interposition goes much further and is where the State sees the need to form itself into a shield for it’s people.
Kansas has stepped very lightly into this domain by way of litigation. Ultimately however when more states are ready to Join Kansas it will be possible to move into full on interposition.
That is where the State will actually refuse to let the illegitimate ‘Federal’ agent stand trial in Federal court. But we are still a long way from being ready for that, Hopefully we won’t even have to go there.
If enough states nullify the Federal encroachments Washington wont have the practical resources to enforce their lawless edicts. Kansas is simply going to make it all that more difficult for the Federal agents to operate unlawfully in the State.
