I know you are talking about throwing out a Presidential election result...
A court can’t throw out an election but election officials can?
Does it depend on the office being contested?

courts throwing out elections
No. All that can happen is that states can decertify. But even if states having 45 EVs decertified, there is absolutely no process in the US Constitution for removing a sitting president other than the looney tunes amendment (25th) or impeachment.
And even if the GOP wins both houses in 2022, there wouldn’t be anywhere close to 67 votes in the Senate to convict.
I’ve been preaching this since last Dec. 14. Once the state legislatures accepted the SecStates’ certifications and sent in the elector slates it was over.
