CAFC tariff argument focusing on what interpreting "regulate" to include tax power would do to other statutes. It would also expand the tax power in IEEPA beyond tariffs! Regulate modifies use, transfer, holding, acquisition-gov't argument means IEEPA authorizes sales taxes, property taxes, etc!

Looking forward to this Friday's colloquium, which puts @aratojulian.bsky.social in conversation w/ @timlmeyer.bsky.social to see how trade & investment treaties can make commitments sufficiently credible w/o overcoming the state’s ability to regulate in the public interest.

My new paper, Presidential Regulation, w/ @ganeshsitaraman.bsky.social, is up: papers.ssrn.com/sol3/papers..... We argue that recent admins have created a new mode of economic governance that is dramatically different how presidents have traditionally used admin tools to regulate the economy. 1/

Law prof @timlmeyer.bsky.social says political compromise involving protectionist measures is necessary to reduce US carbon emissions. My response: That approach won't reduce US carbon emissions much, and also creates international conflict when what is needed is coordination.
