Montgomery v. State of Montana, 375 P.3d 403

Background

Matthew Montgomery pleaded no-contest to felony incest in 2004 (twenty-year suspended sentence) and later pleaded guilty in 2007 to two counts of felony sexual assault, receiving consecutive prison terms and revocation of his 2004 suspended sentence.
Montgomery repeatedly sought to withdraw pleas, vacate convictions, or obtain habeas relief in multiple filings since 2008; this Court repeatedly denied relief on procedural grounds (time-bar, procedural default) or on the merits.
In October 2015 Montgomery filed a pro se "Motion To Vacate Conviction and Dismiss Charges" in Ravalli County District Court; it was summarily denied on November 10, 2015.
Montgomery appealed the denial, arguing a new rule of law and that the court failed to follow constitutionally mandated probable-cause procedures; he also asserted denial of meaningful access to courts as a pro se litigant.
The State argued successive litigation must end, invoking res judicata and procedural bars to repetitive collateral attacks on convictions.
The Montana Supreme Court affirmed the district court, holding Montgomery’s claims are barred by res judicata/claim preclusion and ordering a pre-filing review requirement for any future pleadings from Montgomery challenging the 2004 and 2007 convictions.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the district court erred by summarily denying Montgomery's motion to vacate conviction and dismiss charges	Montgomery: courts skipped constitutionally required probable-cause procedures; pro se access requires meaningful review	State: successive collateral attacks are barred; litigation must end and res judicata applies	Court: Affirmed denial; res judicata/claim preclusion bars relitigation of same issues
Whether habeas/res judicata principles prevent Montgomery's repeated collateral attacks	Montgomery: res judicata inapplicable to habeas; his claims are new or meritorious	State: prior rulings and procedural bars foreclose relitigation; courts previously rejected same arguments	Court: While habeas has special considerations, claim preclusion bars rehearing of previously litigated claims; ends of justice not served by relitigation
Whether Montgomery's pro se status entitles him to further substantive consideration of repeated claims	Montgomery: as pro se, he must have meaningful access and ability to raise claims	State: access does not permit endless relitigation or burden courts	Court: Pro se status doesn't override res judicata; procedures must curb repetitive filings
Appropriate remedy to prevent further repetitive filings	Montgomery: seeks merits consideration and relief	State: requests denial and end to repeated filings	Court: Denied relief and imposed a pre-filing leave requirement (sworn, ≤3 pages) before Clerk will accept future pleadings challenging 2004/2007 convictions
