Does it count if he toots loudly and then leans into the mic and says "pardon me".

@BlackCrusade Hi. The market would resolve "Yes" in this case.

If a pardon is granted and later found unconstitutional?

@MartinRandall Apologies for the delay. If he formally pardons himself but it is later found unconstitutional the question will still resolve to "Yes". It's just based on the action, not the legality.
