No, what’s troubling is that four justices apparently think—or at least are inclined to think—that King was wrongly decided. As I’ve said before, there’s no other reason to take King. The challengers urged the Court to intervene now in order to resolve “uncertainty” about the availability of federal tax credits. In the absence of a split, however, the only source of uncertainty is how the Supreme Court might eventually rule. After all, if it was clear that the Court would affirm in King, there would have been no need to intervene now. The Court could have stood pat, confident that it could correct any errant decisions that might someday arise.
There’s uncertainty only if you think the Supreme Court might invalidate the IRS rule. That’s why the justices’ votes on whether to grant the case are decent proxies for how they’ll decide the case. The justices who agree with King wouldn’t vote to grant. They would instead want to signal to their colleagues that, in their view, the IRS rule ought to be upheld. The justices who disagree with King would want to signal the opposite.
In other words, there are already four justices inclined to think King was wrongly decided. Only five votes are needed to overturn King and find the subsidies invalid.
