Francisco Espinoza v. People of the State of California, 1:25-cv-00976

Francisco Espinoza, a California state prisoner, filed a pro se habeas corpus petition under 28 U.S.C. § 2254, challenging his state convictions and sentence from 2003.
He requested the federal court to investigate whether repealed or amended California penal codes apply retroactively to his case.
His petition was originally filed in the Ninth Circuit, which transferred it to the Eastern District of California.
Espinoza previously sought similar relief in Kern County Superior Court; his petition there was denied and he did not appeal further.
The magistrate judge reviewed the petition for preliminary sufficiency under Rule 4 of the Rules Governing Section 2254 Cases.
The court recommended summary dismissal for failure to state a federal claim and for failure to exhaust state remedies.
