The three judges—Chief Judge Merrick Garland,David Tatel and David Sentelle—were incredulous. You say they want a tax exemption, but that’s not the complaint, Judge Sentelle admonished government lawyer Teresa McLaughlin: “They are not in court seeking to restrain the assessment or collection of a tax, they are in court seeking a constitutionally fair process.”

The suit should also be foreclosed, the government argued, because under Section 7428(b)(2) of the Internal Revenue Code groups may sue to obtain their tax-exempt status if no action has been taken for 270 days, and that should be an alternative to Z Street’s approach.

“You don’t really mean that, right? Because the next couple words would be the IRS is free to discriminate on the basis of viewpoint, religion, race [for 270 days]. You don’t actually think that?” Judge Garland said. “Imagine the IRS announces today a policy that says as follows: No application by a Jewish group or an African-American group will be considered until one day short of the period under the statute . . . Is it your view that that cannot be challenged?”
