President Biden issued several preemptive pardons for crimes which hadn't even been investigated or charged. Will the pardon of any of the individuals in question be ruled unconstitutional and/or invalid by the Supreme Court?

Resolves "yes" if the supreme court strikes down the pardons, or if any court below them does the same and there is no successful appeal. Resolves "no" if the supreme court upholds the pardons as constitutional or refuses to take up the case when the default is constitutionality.

Resolves "N/A" if the pardons are never challenged before SCOTUS and case law is left highly ambiguous as to whether the president's constitutional power to pardon can be used for offenses not charged or investigated.
