A discriminatory law is a statute, regulation, or policy that treats people differently based on a protected characteristic like race, sex, religion, national origin, disability, or age, either explicitly in its text or through outcomes that fall disproportionately on one group. To challenge a discriminatory law, you match the type of discrimination and the type of defendant to the right procedure: an EEOC charge for employment discrimination by a private employer, a Section 1983 suit for constitutional violations by state or local officials, a HUD complaint or lawsuit for housing, and a direct Equal Pay Act suit for wage disparities between men and women doing the same work. Each path has its own deadline, and missing it usually ends the case before a judge ever looks at the merits.
What Counts as a Discriminatory Law
There are two kinds, and the distinction shapes everything about how you challenge them.
The first is facial discrimination, sometimes called de jure discrimination. The words of the law themselves single out a group and impose a different rule. A statute barring members of a particular religion from public office, or a licensing scheme that applies only to women, discriminates on its face. You don’t need statistics or hidden motives; the classification is visible on the page. Courts move quickly in these cases, and the government carries a heavy burden to justify the classification, a burden it rarely meets when race, religion, or national origin is involved.
The second is disparate impact, or de facto discrimination. The rule is neutral on paper but screens out or burdens one group far more than others in practice. The Supreme Court established the principle in Griggs v. Duke Power Co. in 1971, striking down a high school diploma and testing requirement that disproportionately excluded Black applicants and had no real connection to job performance. The Court held that the touchstone is business necessity: a practice that excludes a protected group is prohibited unless the employer can show it is related to job performance, regardless of intent.1Justia. Griggs v. Duke Power Co., 401 U.S. 424 (1971)
Disparate impact reaches modern tools as well. An algorithm that screens résumés or evaluates loan applications can produce biased outcomes if it was trained on historical data reflecting past discrimination. The employer or lender using it remains liable under Title VII and the ADA if the software disproportionately excludes a protected group, even when a third-party vendor built the system.
Which Characteristics Federal Law Protects
Title VII of the Civil Rights Act of 1964 prohibits employment discrimination based on race, color, religion, sex, or national origin, and it applies to employers with at least fifteen employees.2U.S. Equal Employment Opportunity Commission. Title VII of the Civil Rights Act of 1964 In Bostock v. Clayton County, the Supreme Court held in 2020 that Title VII’s ban on sex discrimination also covers sexual orientation and gender identity.3Justia. Bostock v. Clayton County, 590 U.S. ___ (2020)
Other federal statutes fill in specific categories. The Age Discrimination in Employment Act protects workers 40 and older.4U.S. Equal Employment Opportunity Commission. Age Discrimination in Employment Act of 1967 The Americans with Disabilities Act requires reasonable accommodations for workers with physical or mental disabilities.5U.S. Equal Employment Opportunity Commission. The ADA – Your Responsibilities as an Employer The Genetic Information Nondiscrimination Act bars employers and health insurers from using DNA or family medical history against you.6U.S. Equal Employment Opportunity Commission. Genetic Information Discrimination The Equal Pay Act requires equal wages for men and women doing the same work unless a pay gap is explained by seniority, merit, production-based pay, or another factor unrelated to sex.7Office of the Law Revision Counsel. 29 U.S. Code 206(d) – Minimum Wage
Outside employment, the Fair Housing Act prohibits discrimination in the sale, rental, and financing of housing based on race, color, religion, sex, familial status, national origin, or disability.8Office of the Law Revision Counsel. 42 U.S. Code 3604 – Discrimination in the Sale or Rental of Housing The Equal Credit Opportunity Act bars lenders from discriminating based on race, color, religion, national origin, sex, marital status, age, receipt of public assistance income, or exercise of consumer credit rights.9Office of the Law Revision Counsel. 15 U.S. Code 1691 – Scope of Prohibition
The Fourteenth Amendment’s Equal Protection Clause binds state governments, and the Supreme Court has read the Fifth Amendment’s Due Process Clause to impose the same obligation on the federal government.10Constitution Annotated. Amdt5.7.3 Equal Protection That gives courts authority to strike down government action that discriminates even when no statute directly applies.
State and local laws often reach further. Some jurisdictions protect marital status, arrest records, military service, or citizenship status. New York, for example, prohibits age discrimination against workers of any age. When state and federal law overlap, the broader protection usually applies, so checking your state’s civil rights or human rights statute is worth the time.
How Courts Judge Government Classifications
If you are challenging a government law or policy on constitutional grounds, the level of scrutiny a court applies will largely decide the case.
Strict Scrutiny
Strict scrutiny applies to classifications based on race, national origin, religion, and alienage, and to laws burdening fundamental rights like voting or free speech. The government must prove the classification serves a compelling interest and is narrowly tailored using the least restrictive means available. If a less discriminatory alternative could achieve the same goal, the law fails. This standard is almost always fatal.
Intermediate Scrutiny
Sex and gender classifications receive intermediate scrutiny. The government must show the law serves an important objective and is substantially related to achieving it. Stereotypes and administrative convenience are not enough.
Rational Basis Review
Everything else, including classifications based on age, disability, or economic status, gets rational basis review. The law only needs a reasonable connection to a legitimate government interest. Courts defer heavily to the legislature, and most challenges fail at this level unless the classification is truly arbitrary.
Choosing the Right Path
The procedure depends on who is discriminating and where.
Employment Discrimination: File With the EEOC First
For claims under Title VII, the ADA, the ADEA, or GINA, you must file a charge with the Equal Employment Opportunity Commission before you can sue in court. Only after the EEOC issues a right-to-sue letter can you take a private employer to federal court under these statutes. The Equal Pay Act is the exception; you can sue directly without a charge.11U.S. Equal Employment Opportunity Commission. Time Limits for Filing a Charge
State or Local Government Discrimination: Section 1983
When the discrimination comes from a state or local government, 42 U.S.C. § 1983 lets you sue directly in federal court for damages and injunctive relief.12Office of the Law Revision Counsel. 42 U.S. Code 1983 – Civil Action for Deprivation of Rights No administrative charge is required. Section 1983 has real limits, though: it doesn’t reach the federal government or private parties, judges and legislators and prosecutors have immunity for actions in their official roles, and states themselves cannot be sued under it because of sovereign immunity.
Housing and Lending
Housing discrimination victims can file a complaint with the Department of Housing and Urban Development or bring their own lawsuit. When discriminatory lending involves home mortgages, the Department of Justice can pursue the creditor under both the Equal Credit Opportunity Act and the Fair Housing Act.13The United States Department of Justice. The Equal Credit Opportunity Act
The Deadlines That Can End Your Case
For employment charges with the EEOC, the general deadline is 180 calendar days from the discriminatory act. That window extends to 300 days if your state or locality has its own agency enforcing a parallel anti-discrimination law, which most do. For age claims, the 300-day extension only applies if a state law and state agency exist; a local ordinance alone is not enough. Federal employees have just 45 days to contact their agency’s EEO counselor.11U.S. Equal Employment Opportunity Commission. Time Limits for Filing a Charge
In ongoing harassment situations, the clock runs from the last incident, though the EEOC will look at the whole pattern when investigating. Weekends and holidays count toward the deadline, but if the final day falls on one, you have until the next business day. Courts enforce these deadlines strictly.
Exceptions That May Block Your Claim
Two carve-outs come up often enough to check before you file.
The bona fide occupational qualification defense lets employers consider religion, sex, or national origin when one of those traits is genuinely necessary for the job, such as casting actors of a specific sex or staffing a religious school with members of its faith.14Office of the Law Revision Counsel. 42 U.S. Code 2000e-2 – Unlawful Employment Practices Race and color are never eligible. Customer preference alone does not qualify; the trait must be essential to the core function of the business.
The ministerial exception, rooted in the First Amendment, bars employment discrimination claims by ministers against their religious employers. The Supreme Court adopted the doctrine in Hosanna-Tabor Evangelical Lutheran Church and School v. EEOC, holding that forcing a church to keep an unwanted minister would violate the Free Exercise and Establishment Clauses.15Legal Information Institute. Hosanna-Tabor Evangelical Lutheran Church and School v. EEOC, 565 U.S. 171 (2012) In 2020, the Court extended the exception to anyone who performs a religious function at a religious institution, including lay teachers at religious schools. When it applies, Title VII, the ADEA, and the ADA all fall away.
For disparate impact claims under the ADEA specifically, the employer’s defense is easier than under Title VII: rather than showing business necessity, the employer only has to prove the challenged practice was based on a “reasonable factor other than age.” The EEOC considers whether the criterion was defined and applied accurately, whether supervisor discretion was limited, and whether the impact on older workers was considered.16U.S. Equal Employment Opportunity Commission. Questions and Answers on EEOC Final Rule on Disparate Impact and Reasonable Factors Other Than Age
What You Can Recover
Successful employment discrimination cases can produce reinstatement, back pay, front pay, promotion, compensatory damages for emotional harm, and, in cases of intentional discrimination, punitive damages.17U.S. Equal Employment Opportunity Commission. Remedies for Employment Discrimination Federal law caps the combined total of compensatory and punitive damages under Title VII and the ADA based on employer size:18Office of the Law Revision Counsel. 42 U.S. Code 1981a – Damages in Cases of Intentional Discrimination
- 15 to 100 employees: up to $50,000
- 101 to 200 employees: up to $100,000
- 201 to 500 employees: up to $200,000
- More than 500 employees: up to $300,000
Back pay, front pay, and attorney’s fees fall outside the caps and have no statutory ceiling. ADEA claims work differently: no compensatory or punitive damages in the same way, but liquidated damages equal to lost wages are available when the violation was willful.
Housing and lending cases can produce actual damages, injunctive relief ordering changes to the defendant’s practices, and civil penalties.
Retaliation Protection While Your Case Moves
Federal law makes it illegal for an employer to punish you for filing a discrimination charge, testifying in an investigation, or opposing a practice you believe violates anti-discrimination law.19Office of the Law Revision Counsel. 42 U.S. Code 2000e-3 – Other Unlawful Employment Practices Retaliation is a separate violation, so a firing, demotion, or reassignment after you complain creates its own claim even if the original discrimination claim fails. What matters is that you had a good-faith belief the underlying practice was unlawful. Retaliation charges are among the most common the EEOC receives, and they often succeed on their own.
