Malachy E. Mannion
How Judge Mannion decides
Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.
What persuades
In reviewing state-court habeas petitions, he applies AEDPA's doubly-deferential standard strictly and will not revisit a state appellate court's interpretation of state law, even when it forecloses a federal ineffective-assistance claim.
“a state court's interpretation of state law, including one announced on direct appeal of the challenged conviction, binds a federal court sitting in habeas corpus.”
On preliminary-injunction motions, he holds plaintiffs to a strict irreparable-harm requirement and treats purely financial or reputational injury as compensable by damages, not injunctive relief -- the recurring reason his PI denials give.
“Economic loss does not constitute irreparable harm.”
Procedural preferences
He routinely adopts a magistrate judge's report and recommendation in full where no party has objected, reviewing only for clear error rather than re-litigating the analysis himself.
“the report and recommendation of Judge Carlson (Doc. 56) is ADOPTED IN ITS ENTIRETY AS THE RULING OF THE COURT.”
In multi-motion criminal discovery disputes he rules on each defense request individually rather than as a package, granting narrow, well-supported requests (e.g. expert disclosure) while denying broader fishing-expedition requests in the same order.
“Martinez's motion to produce the government's expert information, (Doc. 41), is GRANTED.”
Cautions
Motions for reconsideration face a high bar in his court and are rarely granted absent an intervening change in law, new evidence, or a clear error.
“A motion for reconsideration is a device of limited utility, which may 'not be used as a means to reargue matters already argued and disposed of'”
Suppression motions in his court succeed only on narrow, specifically-supported grounds; broad challenges to searches supported by a valid warrant or corroborated informant tips are consistently denied even after a Franks hearing is granted.
“The Defendant's motion to suppress evidence obtained from his house ... following a Franks hearing, (Doc. 119), is DENIED”
