You’re incorrect.
Here’s the Certificate that the alternate Electors signed:

They didn’t attest that they were alternate Electors - they attested that they were THE Electors for Arizona.
And?
Two sides can legally and genuinely contest that they should be the legitimate electors, without criminalizing one size.
It's happened before in US history.
Now if they forge a signature or seal or if you can prove that they are knowingly giving false information, then that's another thing.
Prove that these people in Arizona don't believe that the election was rigged in AZ and that they should be the legitimate electors.
Incorrect argument.
If somebody steals the official title to your house and the title is no longer in your name, you don't go to court claiming that you are the "alternate home owner". You declare that you are the home owner.
