This bill amends title 5 of the U.S. Code to significantly alter judicial review of agency interpretations of statutory and regulatory provisions. It mandates that courts must decide de novo all relevant questions of law , including interpretations of statutes, regulations, and all forms of agency guidance, rather than deferring to agency expertise. This standard applies universally to agency actions, overriding other laws unless specifically referenced, effectively eliminating judicial deference doctrines like *Chevron* and ensuring courts independently determine legal meaning.
