President Bush spared former White House aide I. Lewis "Scooter" Libby from a 30-month prison term in the CIA leak investigation, calling the sentence too harsh.
The president announced his decision hours after a federal appeals panel ruled that Libby could not delay his prison term, meaning Libby was likely to have to report to jail soon.
The president has broad discretion to exercise presidential power to pardon convicted felons. In this case, the president did not pardon Libby; rather, he waived his prison term. What are the president's powers and how exactly were they used in the Libby case? ABC News consulted experts to sort out the legalese.

The president has the power to commute the sentence or pardon the crime. It is not reviewable and the president doesn't have to give a reason.
Christopher Schroeder, Duke University law and public policy professor
Commutations have always been a lesser included authority under president's power to pardon. Section II of Article II of the Constitution says the president has the power to grant reprieves and pardons for offenses against the United States. It does not mention commutations specifically, but they come under the pardon power.
Randy Barnett, Carmack Waterhouse professor of legal theory at Georgetown University Law Center
Pardon is an "executive forgiveness of crime"; commutation is an "executive lowering of the penalty."
A "pardon wipes out the conviction while a commutation leaves the conviction intact but wipes out the punishment."
Commutation is a form of clemency, used often by governors. A famous example is Illinois Gov. Ryan commuting the death sentences of everyone on death row. By commuting the sentence, Bush was saying, "The crime wasn't forgiven, but the penalty has been reduced." In other words, Bush is saying the "punishment here does not fit the crime." On the other hand, a pardon is granted for a number of reasons: because the punishment doesn't fit the crime, the person is innocent or the prosecutors abused their discretion.
A pardon would have exonerated [Libby] from the crime and all its disabilities. Under a pardon he would have been able to practice law.
Beth Nolan, former Clinton White House counsel
The president's pardon power is either to pardon or commute. To commute he's saying, "I'm not pardoning the crime."
The conviction stays on his record.
He can't vote.
Libby may still appeal his conviction.
Howard Berman, sentencing expert at Ohio State
Re: Libby's Law License: Ultimately up to licensing board from wherever he got his bar. They have been known to make exceptions. He may be able to apply at another bar. It's fair to say most state bars have regulations against allowing felons.
It's outrageous that Bush mentions the harm to his family when his own Justice Department goes into federal court every day and tells judges to disregard those kind of family considerations when deciding what kinds of sentences to impose. Will defendants in federal courts be able to use Bush's statement of reason for commuting Libby's sentence to bolster their own arguments for a less offense?
