re: Can The Supreme Court Intervene After Trump’s Conviction? Legal Experts Say Yes.

The vast majority of the appealable (and likely to be won) issues are state court stuff, like the jury instructions, evidentiary rulings (witness testimony, objections, etc.). The primary Constitutional issue is the ruling about non-unanimity with the jury instructions up to the statute itself being unconstitutional. The latter is the one way the USSC can end this.

Otherwise, it just goes back for a new trial with the same jury pool and judge, but with the offending ruling being corrected.
