I don't know what an Appeals Court can do, and I would like to know.

It almost certainly could provide the relief the plaintiffs were asking for, right?

Can it:

    * provide a writ of mandamus stopping the machines until the ordered report is provided?
    * tell the TSA 19 months is too long, they have 90 more days to comply?

As it was, IIRC, the TSA said 19 months, the judge said 20 months!
