Stephen V. Kolbe v. Martin J. O'Malley
42 F. Supp. 3d 768
D. Maryland2014Background
- Maryland enacted the Firearm Safety Act of 2013, banning certain listed "assault" long guns (and their "copies") and prohibiting detachable magazines holding more than 10 rounds; limited exemptions for retired law enforcement officers and existing lawful possessors.
- Plaintiffs (individuals, gun dealers, and associations) sued state officials seeking a declaratory judgment that the Act violates the Second Amendment, Equal Protection, and is void for vagueness; preliminaries denied and case decided on cross-motions for summary judgment.
- The State defended with legislative purpose and extensive evidentiary record (expert testimony, law-enforcement declarations, studies) asserting the bans further public safety by reducing availability and lethality of weapons and magazines used disproportionately in mass shootings and some officer murders.
- Court considered Daubert and disclosure challenges to several defense experts and witnesses and denied motions to exclude, finding the testimony admissible and any disclosure failures harmless or justified.
- On the merits, the court assumed the bans burden Second Amendment interests, applied intermediate scrutiny, and found the Act substantially related to Maryland’s interest in public safety; it rejected plaintiffs’ Equal Protection and vagueness challenges.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Second Amendment infringement (ban on assault long guns & large-capacity magazines) | Ban prohibits commonly owned, lawfully used weapons for self-defense and recreation; therefore it burdens protected conduct | Banned items are not central to self-defense, are military-style and disproportionately used in mass shootings and officer killings; law advances public safety | Court assumed an infringement but upheld the Act under intermediate scrutiny as substantially related to public safety interests |
| Level of scrutiny to apply | Plaintiffs: common-use weapons bans touching core right require strict scrutiny | Defendants: law does not substantially burden core home-defense right; intermediate scrutiny appropriate | Court applied intermediate scrutiny because the ban leaves ample alternatives for home defense and does not destroy core right |
| Equal Protection (retired officer exemptions) | Exempting retired officers treats similarly situated citizens differently without rational basis | Retired officers are differently situated due to extensive training, ongoing qualification, and public-safety role; exemption rationally relates to safety | Court found retired officers not similarly situated and upheld exemption under rational-basis review |
| Vagueness ("copies"/listed models) | Term "copies" and model-based list fail to give fair notice and permit arbitrary enforcement | List of specific makes/models, long usage in Maryland law, AG opinion and MSP guidance/administrative procedures provide narrowing and notice | Court rejected facial vagueness challenge, finding a clear core of prohibited conduct and administrative guidance limiting enforcement |
