Reliability Notes

Journalist-hosted copy of the PACER complaint bearing Case 5:26-cv-09217, Document 1, filed August 28, 2026. Primary for what the publisher plaintiffs alleged at filing, including counts and the named defendants. Not a substitute for a RECAP/PACER original, and not evidence of the truth of disputed facts. No merits order is recorded in this source.
