"Acceptance, as well as delivery, of a pardon is essential to its validity; if rejected by the person to whom it is tendered, the court has no power to force it on him. [...]
There are substantial differences between legislative immunity and a pardon; the latter carries an imputation of guilt and acceptance of a confession of it [...].
The facts, which involve the effect of a pardon of the President of the United States tendered to one who has not been convicted of a crime nor admitted the commission thereof, and also the necessity of acceptance of a pardon in order to make it effective are stated in the opinion."

It's fair to argue that there is no precedent, but that just means it hasn't happened before, not that it cannot happen.
