NOT AN LLC D/B/A JSD SUPPLY’S JOINDER TO DEFENSE DISTRUBUTED

AND BLACKHAWK MANUFACTORING GROUP INC. D/B/A 80 PERCENT ARMS’ 

EMERGENCY MOTIONS FOR INJUNCTIVE RELIEF PENDING APPEAL

Intervenor Plaintiff Not An LLC d/b/a JSD Supply (“JSD Supply”) joins Intervenors 

Defense Distributed and Blackhawk Manufacturing Group Inc., d/b/a 80 Percent Arms’ emergency 

motions for injunctive relief pending appeal (Doc(s). 249, 251), and states: 

STATEMENT OF JOINDER 

To avoid duplicating efforts and unnecessarily compounding these proceedings, JSD 

Supply joins, in full, Defense Distributed and Blackhawk Manufacturing Group Inc., d/b/a 80 

Percent Arms’ emergency motions for injunctive relief pending appeal (Docs. 249, 251). 

JSD Supply respectfully incorporates by reference the arguments made in Defense 

Distributed’ s Emergency Motion for Injunction Pending Appeal (Doc. 249) and 80 Percent Arms 

Emergency Motion for Injunction Pending Appeal (Doc. 251). JSD Supply also respectfully 

incorporates by reference its earlier memorandum of law in support of its motion for preliminary 

injunction (Doc. 152). In addition to their joinder, JSD Supply offers the declaration of Jordan 

Vinroe (Doc. 151-1), attached hereto as Exhibit A, and supplemental declaration of Jordan Vinroe

2 

(Doc. 213-1), attached hereto as Exhibit B as evidence of the irreparable harm JSD Supply and its 

customers will suffer absent a preliminary injunction. 

On September 14, 2023, the Court granted Intervenors’ emergency motions for injunctive 

relief pending appeal (Doc. 261) to enforce unstayed portions of the Court’s Order Granting 

Summary Judgment (Doc. 227) and Final Judgment (Doc. 231) against the Government 

Defendants. 

CONCLUSION

The Court should enter an injunction pending appeal ordering that, until the matter’s

appeals are concluded, Defendants and their officers, agents, servants, and employees are enjoined

from implementing and enforcing against JSD Supply and its customers (except for those

individuals prohibited from possessing firearms under 18 U.S.C. § 922(g)) the provisions in 27

C.F.R. §§ 478.11 and 478.12 that the Court has preliminarily determined are unlawful.
