Have a two part trial, with two juries.

Part one, with jury #1, just considers the facts. It does not attempt to apply the law to the facts to render a guilty/not-guilty verdict.

Part two presents the facts as determined in part one to jury #2 (which was not present during part one), and jury #2 applies that law to those facts to render a verdict. The facts as presented to jury #2 are cleaned up to replace names with pseudonyms, and race, gender, etc., are removed (unless they are relevant to the applicable law).

That's essential how the appeals system works. Appeals don't reconsider facts, just the application of the law.
