When Moore v United States landed on the Supreme Court docket, it threatened to take a big swing at any future wealth tax and maybe cut the legs out from under the government’s ability to collect a lot of other tax. But as arguments unfolded Tuesday at One, First Street, it became clear that some of the Justices had studied up on the tax code and were cooling on blowing a big hole in it.  To understand why Moore made it all the way up to SCOTUS in the first place, and why the facts don’t match claims from the plaintiffs, Dahlia Lithwick is joined by law professor and author of Big Dirty Money, Professor Jennifer Taub. Together they talk about the billions behind the case, the tax law, and the arguments inside the chamber.  Next, Dahlia is joined by Slate’s Mark Stern, who covered Moore for the magazine, to discuss Justice Alito's non-recusal from the case, his BFF David Rivkin Jr., and why the plaintiffs Mr and Mrs Moore bear a striking resemblance to some other, recent, fabled SCOTUS plaintiffs.  In this week’s Amicus Plus segment, Mark Stern hangs on to talk about the Title VII case this week that didn’t go *that badly*, and why that’s still not good, and to explain why Justice Elena Kagan has had it up to here with false first principles.  Sign up for Slate Plus now to listen and support our show.  Dahlia’s book Lady Justice: Women, the Law and the Battle to Save America, is also available as an audiobook, and Amicus listeners can get a 25 percent discount by entering the code “AMICUS” at checkout.
