Does the law allow for the Attorney General to MAKE that call?
I don’t know, but I suspect that an AG can abrogate an agreement with another state if the agreement allows for it. There may be a statement such as: either party may abrogate given 30 or 60 day notice of doing so. But, concerning concealed carry permit reciprocity, I don’t know if there is a law or just a state government to state government agreement.
