Equal protection requires states to treat people fairly and equally under the law. But "equally" doesn't mean "identically." The Fourteenth Amendment allows states to draw legal distinctions—taxing corporations differently than individuals, setting age limits for voting, requiring licenses for professions. The constitutional question is whether these distinctions are justified.
Courts apply three levels of scrutiny depending on the classification. Strict scrutiny applies when laws single out people by race, national origin, or religion—categories with a history of discrimination. The government must prove a compelling interest and use the least restrictive means. Almost every law fails strict scrutiny. Intermediate scrutiny applies to gender and legitimacy classifications. The government must show an important interest and a substantial relationship between the classification and that interest. Rational basis review applies to all other classifications—economic policy, professional licensing, age requirements. The government just needs a rational reason; courts almost never strike down laws under rational basis.
The level of scrutiny chosen often determines the outcome. States can restrict marriage in many ways under rational basis. But a blanket ban on same-sex marriage faced heightened scrutiny for treating a disfavored group differently.
Equal protection prevents government from treating some people as less worthy of rights or dignity than others. Without it, states could license only doctors of a certain race, exclude immigrants from professions, or deny voting rights based on wealth. It's why voting rights, education access, and criminal justice outcomes remain central to civil rights debates.
People often think equal protection means identical treatment. In fact, the Constitution permits many different legal classifications. The real question is whether classifications are justified. Why does age matter for voting but not for housing? Why can states require professional licenses but not religious tests? Equal protection requires government to answer these questions.
