“One of the most widely used textbooks on ConLaw”? Even his own school doesn’t make that claim. Con Law textbooks begin and end with Chemerinsky. Nor does it make any claims about his treatises. That is beside the point, however. My point is not that Rotunda is not qualified. My point is that you can’t just point to things he said because they don’t stand up to even casual scrutiny. My own qualifications, incidentally, are irrelevant because I am not citing myself. Since you asked, I’m a (new) lawyer who practices administrative law.
Footnote 37 - and yes, that’s the one I meant - is an excellent example. The problem there is that the footnote is supposed to support his assertion - that prosecutorial discretion exists only in the criminal sphere. It doesn’t; in fact, on its face the dicta cited stands for the opposite proposition. Rotunda then argues that it doesn’t matter what the dicta says because what it means is something different. Conspicuously absent from the footnote is a citation that actually does offer support.
If that’s a little dense, I’ll put it another way: Rotunda says X. He then cites a case in which the Supreme Court said the opposite of X, and explains* why that particular holding is not actually on point, and therefore irrelevant. The reader is presumably supposed to infer that X is true because the Supreme Court didn’t say it was not true (at least in that one case.) While I hesitate to accuse him of fabrication, it appears to be a conjuring trick.** There is absolutely zero chance that Rotunda genuinely believes that there is no such thing as prosecutorial discretion outside the field of criminal law. It’s laughable. It’s as demonstrably false as if I claimed the Fifth Amendment only applied in the District of Columbia.
Try this: call any agency in your state, ask for a lawyer in their enforcement division, and ask if the agency exercises prosecutorial discretion.
*You are apparently happy to take his word for it when he says the case he is citing (Heckler) is not on point (though that brings up the thorny question of why he cited it in the first place.) In fact, Heckler is directly on point, because it isn’t a standing case at all. It is almost entirely about the FDA’s prosecutorial discretion - as the very next paragraph in the case makes clear.
These factors are the raison d’etre of prosecutorial discretion in any context. Read Heckler for yourself and then decide if it says what Rotunda claims it does.
**A more thorough reading of his testimony in its entirety suggests that his elder years may have caught up with him. He mentions a conservative boogeyman that even the most overwrought of Fox News guests doesn’t actually take seriously:
