U.S. District Court Denies Injunction of Colorado Equal Pay Law

Legal Updates

Last week, in the case of Rocky Mountain Association of Recruiters v. Moss, Case No. 1:20-cv-03819 (U.S.D.C. Colo.), U.S. District Judge William J. Martinez denied a plaintiff’s request for a preliminary injunction to block portions of Colorado’s Equal Pay for Equal Work Act (EPEWA). The EPEWA, which went into effect beginning this year, aims to close the gender wage gap in Colorado by prohibiting employers from paying an employee of one sex less than the other sex for substantially similar work (Part 1) and by requiring employers to follow strict job posting and pay transparency rules (Part 2).

Plaintiff’s constitutional challenge

The lawsuit noted above challenges the EPEWA’s promotion and compensation posting requirements on constitutional grounds. Under the promotion posting requirement, employers must notify current employees of all promotion opportunities, with certain exceptions. The law’s compensation posting requirement mandates that employers include in every job posting:

  • the expected compensation or range for the position;
  • a description of any bonuses, commissions or other forms of compensation being offered; and
  • a description of all employee benefits available.

The plaintiff specifically asserts that these requirements violate the Dormant Commerce Clause and First Amendment protections of commercial speech. Based on these claims, plaintiff sued Scott Moss in his official capacity as the Director of the Division of Labor Standards and Statistics of the Colorado Department of Labor and Employment (Division) and requested a preliminary injunction prohibiting the Division from enforcing both provisions.

District Court denies plaintiff

In denying the request, Judge Martinez held that the plaintiff failed to offer sufficient evidence to show a “substantial likelihood of success on the merits” for either claim, a required showing when seeking a preliminary injunction.

Under the Dormant Commerce Clause, states are prohibited from enacting laws that discriminate against interstate commerce or unduly burden interstate commerce in relation to the state’s local benefits. In asking for a preliminary injunction, the plaintiff alleged that the promotion and compensation posting requirements unduly burden interstate commerce in relation to the state’s claimed public benefit of improving gender pay equity. Specifically, it argued there was no evidence that the posting requirements would reduce the pay gap and that any potential benefits were outweighed by the requirements’ burdens and costs on employers conducting interstate hiring.

Judge Martinez disagreed, finding that the plaintiff’s primary evidence of interstate burdens—employer costs inside Colorado—was insufficient at this stage in the case to show “the relative magnitude of the local benefits, as compared to the burdens on interstate commerce,” created by the EPEWA and its implementing regulations.

Similarly, Judge Martinez cast aside the plaintiff’s First Amendment claim, agreeing with the Division that the posting requirements have a reasonable relationship to the government interest of reducing the gender wage gap and that the requirements were not particularly onerous to chill commercial speech. He stated that although the Division had not produced “empirical proof” that the law will have a demonstrable effect on the gender wage gap, such certainty was not required to justify the restrictions. He also noted that the posting requirements only mandate the disclosure of factual information and that employers were still free to include additional information that may serve specific applicants or minimize confusion.

What this means to you

While the result of this District Court matter failed to stall EPEWA’s implementation or enforcement, it did leave the door open—narrowly—for future claims. The order indicates that the plaintiff may be able to strengthen its Dormant Commerce Clause claim after it gathers additional evidence on the interstate impacts of the posting requirements.

We will continue to monitor this case and provide updates as it develops. In the meantime, the EPEWA’s promotion and compensation posting requirements stay in effect and employers should ensure that their hiring policies remain in compliance.
