There's lots of good explanations of what the US Constitution allows... but they don't actually matter!
No matter which branch of government (executive, judicial, or legislature) have the power to "do away with pardons" the same has the power to bring them back.
In parliamentary systems this is called the "supremacy of parliament".
So even if Biden could issue an executive order to stop pardons then Trump can just executive order them back.
There's a lot of radical things Biden could do to better shelter the people of the US and indeed the world from the coming storm but, being Joe Biden, he's going to do none of them.
It's baked into the US Constitution and the framers intentionally made it difficult to ratify amendments to prevent it from being changed frequently on whims (the Constitution should ideally be able to weather any change in the breeze). He could but he'd need 2/3rds of both House and Senate to vote in favor in order to proceed, so he'd need those to be in session to vote, and then ratification is even messier, I think 2/3 or 3/4 of state legislatures need to vote in favor of ratification. Bunch of hurdles that require not only getting all these groups in a room, but also to have well over a majority vote in favor.
And we all know Marlie Tator Greene would be screaming the whole damn time, so snowball's chance in hell basically
Article II, Section 2, Clause 1 of the U.S. Constitution, which provides: The President ... shall have Power to grant Reprieves and Pardons for Offenses against the United States
In order to change that, would need a Constitutional Amendment, which require ratification from 38 out of 50 states, so, unlikely
Joe Biden can do whatever he wants and it doesn't matter because then Trump will do whatever he wants. He can do away with pardons and then Trump can decree that they exist again. There's nothing left to stop him. Buckle up.
It would be irrelivant. Trump will change anything and everything to suit his needs. You can change whatever you want and he'll just change it back on day one. You know, that one day he made very clear that he was going to be a dictator. That's the one day set aside to change every single thing he needs to. After that, nothing else matters.
He can do whatever he wants, the supreme Court is dumb enough to say so, he can post troops at the front of their swear in and mow down both of them before they get sworn in. If he does nothing to stop it after that. " He would get impeached" and be out of a job.. but cannot get penalties against him for doing so. The supreme Court is the most supreme dumbasses we have seen in our lives. I thought my parents were stupid. They are making feathers look smart. Will Biden, no, will trump, yes. We know better
The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.
The President can pardon anyone he wants for any federal crime as long as it's backward looking. He can't pardon someone for something that will happen in the future.
The President does not have the power to abolish pardons.
