Equal protection is a fundamental principle in U.S. law, rooted in the 14th Amendment . It prohibits discrimination and ensures fair treatment under the law, shaping civil rights jurisprudence and addressing historical inequalities.
Courts use different levels of scrutiny to evaluate equal protection claims, from strict scrutiny for race-based laws to rational basis for most other classifications. This framework balances individual rights with government interests, evolving to address new forms of discrimination.
Historical background of equal protection
Equal protection clause emerged as a cornerstone of civil rights law in the United States

Aimed to address racial discrimination and ensure equal rights for newly freed slaves
Contains the Equal Protection Clause stating "nor shall any State deny to any person within its jurisdiction the equal protection of the laws"
Marked a significant shift in federal power to protect individual rights against state actions
Post-Civil War developments
Civil Rights Act of 1875 attempted to implement equal protection principles
Faced resistance and limited enforcement in Southern states
Supreme Court's narrow interpretation in Civil Rights Cases (1883) restricted federal power
Jim Crow laws emerged, perpetuating racial segregation despite 14th Amendment guarantees
Plessy v. Ferguson (1896) upheld "separate but equal" doctrine, limiting equal protection's scope
Early Supreme Court interpretations
Initially applied equal protection narrowly, focusing primarily on racial discrimination
Strauder v. West Virginia (1880) struck down a law excluding Black citizens from juries
Yick Wo v. Hopkins (1886) extended equal protection to non-citizens, addressing discrimination against Chinese immigrants
Gradually expanded scope to include other forms of discrimination beyond race
Brown v. Board of Education (1954) overturned Plessy, marking a turning point in equal protection jurisprudence
Levels of scrutiny
Developed by the Supreme Court to evaluate the constitutionality of laws under equal protection
Reflect different degrees of judicial review based on the nature of the classification or right affected
Play a crucial role in determining the outcome of equal protection challenges in U.S. courts
Strict scrutiny standard
Highest level of scrutiny applied to suspect classifications (race, national origin, religion)
Government must prove law is narrowly tailored to achieve a compelling government interest
Presumption of unconstitutionality places heavy burden on government to justify the law
Rarely survives strict scrutiny, often described as "strict in theory, fatal in fact"
Applied in cases involving fundamental rights (voting, interstate travel, access to courts)
Middle tier of scrutiny applied to quasi-suspect classifications (gender, legitimacy)
Government must show law is substantially related to an important government interest
More flexible than strict scrutiny but still requires significant justification
Developed in Craig v. Boren (1976) for gender-based classifications
Also applied in some First Amendment cases involving commercial speech
Rational basis test
Lowest level of scrutiny applied to most other classifications
Law must be rationally related to a legitimate government interest
High deference to legislative judgments, presumption of constitutionality
Government action typically survives rational basis review
Applied to economic regulations, age classifications, and non-fundamental rights
Occasionally used as "rational basis with bite" in cases like Romer v. Evans (1996)
Protected classes
Groups specifically identified for protection against discrimination under equal protection laws
Reflect historical patterns of discrimination and societal recognition of vulnerable populations
Influence the level of scrutiny applied in equal protection analysis
Continue to evolve as societal understanding of discrimination changes
Race and national origin
Subject to strict scrutiny, reflecting the 14th Amendment's original purpose
Prohibits both overt discrimination and facially neutral laws with discriminatory impact
Covers all racial and ethnic groups, not just historically disadvantaged minorities
Includes protections against racial profiling, segregation, and employment discrimination
Extends to discrimination based on ancestry or place of birth
Gender and sex
Initially subject to rational basis, now evaluated under intermediate scrutiny
Covers discrimination against both men and women
Prohibits gender stereotyping and overly broad generalizations about gender roles
Includes protections against pregnancy discrimination (Pregnancy Discrimination Act )
Recent cases have expanded interpretation to cover sexual orientation and gender identity
Religion
Protected under both Equal Protection Clause and First Amendment's Establishment Clause
Government actions targeting specific religions subject to strict scrutiny
Covers both religious belief and practice, including protections for religious minorities
Balances religious freedom with other constitutional rights and government interests
Includes protections against religious discrimination in employment, education, and public accommodations
Age vs disability
Age discrimination generally subject to rational basis review
Age Discrimination in Employment Act provides statutory protections for workers over 40
Disability discrimination addressed primarily through Americans with Disabilities Act (ADA)
ADA requires reasonable accommodations and prohibits discrimination in various contexts
Courts have applied a form of heightened scrutiny to disability discrimination in some cases
Disparate treatment vs disparate impact
Two primary theories for proving discrimination under equal protection and civil rights laws
Reflect different ways in which discrimination can manifest in policies and practices
Crucial distinction in determining the appropriate legal analysis and burden of proof
Intentional discrimination analysis
Focuses on proving discriminatory intent or purpose behind a law or action
Requires evidence of deliberate discrimination against a protected class
Can be demonstrated through direct evidence or circumstantial evidence of bias
Applies strict scrutiny to racial classifications, even if benign or remedial in nature
Challenging to prove in cases where discrimination is subtle or unconscious
Unintentional discrimination effects
Addresses facially neutral policies that disproportionately affect protected groups
Does not require proof of discriminatory intent, focuses on discriminatory outcomes
Recognized in Griggs v. Duke Power Co. (1971) under Title VII of Civil Rights Act
Allows challenges to practices that perpetuate historical discrimination
More commonly applied in statutory contexts than constitutional equal protection claims
Burden of proof considerations
Disparate treatment cases require plaintiff to prove discriminatory intent
McDonnell Douglas burden-shifting framework often used in employment discrimination cases
Disparate impact cases require plaintiff to show statistical disparity in outcomes
Defendant can rebut by demonstrating business necessity or job-relatedness of practice
Plaintiff may still prevail by showing alternative practices with less discriminatory impact
Affirmative action
Policies and programs designed to benefit underrepresented groups in education and employment
Controversial application of equal protection principles to address historical discrimination
Subject to ongoing legal challenges and evolving Supreme Court jurisprudence
Balances remedial goals against concerns of reverse discrimination
Educational context
Focuses on increasing diversity in higher education admissions
Grutter v. Bollinger (2003) upheld narrow use of race as one factor in holistic review
Fisher v. University of Texas (2016) reaffirmed but clarified strict scrutiny standard
Prohibits racial quotas or point systems based solely on race
Requires periodic review to ensure continued necessity of race-conscious policies
Employment context
Addresses underrepresentation in hiring, promotion, and contracting
Voluntary programs must meet strict scrutiny standard if challenged
Court-ordered remedies may be imposed to address proven past discrimination
Executive Order 11246 requires affirmative action plans for federal contractors
Private employers must navigate Title VII restrictions on preferential treatment
Strict scrutiny application
Affirmative action programs must be narrowly tailored to achieve compelling interest
Diversity in higher education recognized as compelling interest in Grutter
Remedying specific, identified past discrimination may justify limited use of race
Programs must consider race-neutral alternatives before adopting race-conscious measures
Time-limited nature emphasized, with expectation of eventual phase-out

Challenges arise in balancing racial considerations with other redistricting criteria
Voter ID laws
Subject to equal protection challenges if disproportionately affecting minority voters

Requires evidence of both discriminatory effect and discriminatory purpose
Challenges in obtaining discovery to prove selective prosecution claims
Recent focus on racial disparities in drug prosecutions and charging decisions
Jury selection
Batson v. Kentucky (1986) prohibits race-based peremptory challenges in jury selection

Public vs private discrimination
Constitutional equal protection applies only to state actors, not private individuals
Civil Rights Act of 1964 and other statutes address private discrimination
State action required for constitutional claims, limiting reach of 14th Amendment
Challenges in defining state action in era of privatization and public-private partnerships
Private conduct may become state action if sufficiently entwined with government functions
Exceptions to state action requirement
Public function exception applies when private entities perform traditional government functions
Entanglement exception when government significantly involves itself with private conduct
State compulsion when government coerces or encourages private discriminatory action
Symbiotic relationship where government and private entity share responsibilities
