Ford pardoned Nixon precluding prosecution, so there is precedent.

Maybe, but I think if challenged in court it would not stand as Ford is no longer President. Any legal scholars can enlighten up?

I think Ford was/is on shaky ground.

I don't think that was ever challenged in court and without a ruling, I question its legality. As no one ever pushed the issue, Ford got away with it.
