SpaceX has filed a second lawsuit in Texas challenging the constitutionality of the National Labor Relations Board, after its first suit was transferred from Texas to California last month. The new complaint rehashes two arguments that SpaceX made in its initial suit: that the NLRB’s members and the agency’s administrative law judges are impermissibly shielded from removal by the President.

The new suit is likely a second attempt to have these constitutional claims heard in the Fifth Circuit, which is under increasing scrutiny for its zeal in curtailing federal agencies’ power. SpaceX’s first suit was transferred to California because the underlying unfair labor practice proceedings had a weak connection to the state of Texas, leading a judge in the Southern District of Texas to conclude that venue in Texas was improper. SpaceX’s new suit seeks to halt ongoing ULP proceedings in which the NLRB is challenging the company’s severance agreements and forced arbitration clauses. While these ULP charges were issued in Seattle, the challenged contractual terms apply to SpaceX employees across the country, leading the company to argue that Texas is an appropriate forum for its new suit. Labor law experts will continue to watch both SpaceX suits closely.
