Wow - Warrants pretty much went by the wayside after Regulation CC came about in the late 80's. As if it looks like a check, it has to be treated as a check. What are your specific concerns? If you are the account holder institution, you should have some real strong agreements for any public entity that are issuing what they call a warrant, including having to notify you within 24 hours of presentment if they do not want them paid.
