Felix Rosado v., 7 F.4th 152

In 1995 Rosado (age ~18½) killed Hiep Nguyen, pleaded guilty to first-degree murder, and was sentenced to mandatory life without parole.
Rosado pursued collateral relief for years; earlier ineffective-assistance claims failed.
Miller v. Alabama (2012) barred mandatory LWOP for offenders under 18; Montgomery v. Louisiana (2016) made Miller retroactive.
After Montgomery, Rosado filed a state PCRA petition (2016) arguing Miller; state court dismissed it as time-barred.
In 2018 Rosado sought permission under 28 U.S.C. § 2244(b) to file a second federal habeas petition based on Miller.
The Third Circuit had to decide (1) whether it may consider timeliness at the gatekeeping stage and (2) whether Rosado’s claim actually “relies on” Miller.

Issue	Rosado's Argument	Commonwealth's Argument	Held
May the court consider AEDPA timeliness when deciding whether to authorize a second/successive §2254?	Courts of appeals should not deny leave on timeliness; only §2244(b) criteria matter.	Courts may deny leave on other clear defects like untimeliness.	Courts may consider timeliness but only rarely; must give notice and avoid unresolved factual/tolling disputes.
Does Rosado’s claim “rely on” Miller given he was over 18 at the offense?	Miller’s reasoning about adolescent brain development applies to immature young adults close to 18, so his claim rests on Miller.	Miller drew a bright line at under-18; Rosado was older, so his claim is outside Miller’s limits.	Rosado does not rely on Miller; Miller’s bright-line age limit bars extending it to him.
