I certainly don't know, and I suspect legal experts might even have differing opinions! What happens if H.R. 139 passes, striking the eastern time zone's “5 hours” and inserting “4 hours”, but then H.R. 7389, the *Motor Vehicle Modernization Act* into which it was incorporated, also gets passed later? Does the “4 hours” get replaced again with “3 hours”, yielding permanent double daylight time in most regions? Perhaps that is the case if no one notices! But I should hope someone would. So the main reason primacy is important is it that sets the context in which later bills are applied. All of this is to say I suspect those involved try to avoid such conflicts whenever possible. In practice, it's *incredibly* unlikely (though not impossible) that any given Congress with a given President would "undo" its own legislation in such rapid succession as these thought-exercises might suggest. And since all of these bills die anyway on 3 January 2027 once the new Congress sits, these things tend to be redrafted when they're being reintroduced in a new Congress — though not always well, and that's part of what the committee review stage is for. But folks are only human and anything is possible if a mistake slips through. I suppose that's also what the courts are for. -- Tim Parenti
