Fabricated or misquoted citations

On 2026-05-29, in Jaclyn Cocco v. Rosario Palmieri, Jr, Supreme Court of Pennsylvania affirmed and observed that an asserted parental-alienation authority could not be located. A self-represented appellant filed a petition using quotations that did not appear in the cited source, nonexistent or hallucinated authorities, and authorities used for propositions they did not support.

Disposition: The court affirmed the custody order and noted counterfeit authority in the pro se father’s brief without imposing a consequence.
Recorded conduct: The pro se father cited fake parental-alienation authority and cases that did not say what he claimed. The court affirmed and imposed no consequence for the citation issue. — outcome: noted, no consequence; actor: litigant in person
Canonical record: Incident tracker entry — verified outcome, regulator disposition and related rules
