All of these variations are quintessentially legislative judgments. It would be very difficult for the Framers to have eschewed deciding 14 years was a constitutional limitation, and for this Court to say 99 years is, and again, even the petitioners aren't asking the Court to make that judgment.
The variations are quintessentially judgments for the petitioners.
The text says "All of these variations are quintessentially legislative judgments", so legislators, not petitioners. The sentence is confusing to me and the model.
