The Trump administration’s Department of Justice (DOJ) has released an opinion that signals a significant weakening of worker protections, directly extending the Supreme Court’s recent voting rights decision in Louisiana v. Callais to employment discrimination cases. This move, detailed in an opinion from the Office of Legal Counsel (OLC) on Tuesday, June 10, 2026, threatens to make it substantially harder for plaintiffs to prevail in employment discrimination lawsuits, particularly those relying on the ‘disparate impact’ framework.
The OLC opinion, signed by T. Elliot Gaiser, a former law clerk to Justice Samuel Alito, argues that Alito’s reasoning in Callais — which repealed a 1982 amendment to the federal Voting Rights Act — applies with equal force to anti-discrimination law in employment. Just one day after Gaiser’s opinion, the Trump Department of Transportation announced it was applying Callais to its own regulations, indicating a broad governmental effort to implement this legal interpretation across the executive branch.
The Callais Precedent and its Extension
The Callais decision, authored by Justice Alito, effectively removed the ‘results’ test from the Voting Rights Act. This test previously allowed plaintiffs to challenge state election laws that diminished voting rights due to race, even without proving racist intent on the part of lawmakers. For 40 years, this meant states sometimes had to create districts where Black or Latino voters could elect their preferred candidates. Post-Callais, lawmakers can now draw maps that favor white Republicans, so long as they assert the purpose is political advantage rather than racial targeting.
Gaiser’s opinion leverages this precedent to argue that federal employment discrimination law, specifically the 1991 federal law concerning disparate impact, should also require a strong inference of intentional discrimination. The 1991 law permits plaintiffs to prevail if they can show an employer engages in a ‘practice that causes a disparate impact on the basis of race, color, religion, sex, or national origin,’ without necessarily proving malicious intent. Gaiser, quoting from Callais, asserts that employment discrimination law ‘imposes liability only when the circumstances give rise to a strong inference that intentional discrimination occurred.’
This interpretation has two critical implications. Firstly, it will significantly complicate and reduce the success rate of employment discrimination plaintiffs. Secondly, and perhaps more profoundly, it undermines the power of elected officials to enact and enforce comprehensive civil rights protections, effectively shifting the primary role of defining civil rights law to the Supreme Court.
Disparate Impact, Explained
The concept of disparate impact in employment law predates the 1991 congressional codification. The Supreme Court first recognized its validity in the unanimous 1971 decision, Griggs v. Duke Power. In Griggs, an employer’s new policy requiring a high school diploma for higher-paying jobs disproportionately affected Black workers, while white workers without diplomas were grandfathered into those roles. The Court ruled that such requirements, if they have a disproportionate negative impact on racial minorities, must be ‘a reasonable measure of job performance.’
Congress later enshrined this principle in the 1991 law, stipulating that employment practices causing a disparate impact are forbidden unless the employer can demonstrate the practice is ‘job related for the position in question and consistent with business necessity.’ This framework has been crucial for addressing systemic biases that may not stem from overt, intentional discrimination.
Republican judges have historically expressed skepticism regarding disparate impact suits. In Ricci v. DeStefano (2009), five of the Court’s Republican justices rejected a challenge to a firefighter promotion exam that disproportionately screened out minority candidates. Justice Antonin Scalia, in a concurring opinion, even suggested the 1991 law itself might be unconstitutional. Despite this, the law, and a similar one for housing discrimination, remain technically valid.
During the Obama administration, the DOJ actively utilized disparate impact lawsuits. For instance, mortgage lender Countrywide agreed to pay $335 million to settle claims that it ‘charged higher fees and rates to more than 200,000 minority borrowers across the country than to white borrowers who posed the same credit risk.’ This demonstrates the practical power of disparate impact claims in addressing widespread discriminatory practices.
The Future of Worker Protections
The implications of the Trump administration’s stance on disparate impact are far-reaching. It could significantly curtail the ability to challenge discriminatory practices, particularly in an era where complex algorithms and artificial intelligence are increasingly used in hiring. If an AI system, for example, develops a hidden bias that disproportionately screens out Black candidates, under this new interpretation, proving discriminatory intent on the employer’s part would become an insurmountable hurdle for plaintiffs.
This legal shift represents a profound reinterpretation of civil rights legislation, moving away from outcomes-based protections towards a stricter requirement of proving intent. This approach aligns with a broader Republican strategy to weaken civil rights laws and centralize the interpretation of such protections within the judiciary, particularly a conservative-leaning Supreme Court. The ultimate impact will likely be a substantial reduction in successful employment discrimination claims and a greater challenge for workers seeking justice against systemic biases.
