State Action Doctrine The Constitution only restricts GOVERNMENT action, not private conduct. State action exists when: (1) PUBLIC FUNCTION - private entity performs traditional, exclusive government function (running elections, company towns); (2) ENTANGLEMENT - government is significantly involved through regulation, subsidies, or authorization; (3) JUDICIAL ENFORCEMENT - court enforces private discrimination (Shelley v. Kraemer). Key traps: Heavy regulation alone is NOT enough. Private schools receiving tax exemptions = NO state action. Look for government compelling or encouraging the specific discriminatory act. HYPO: A private country club refuses to admit Black members. A rejected applicant sues under the Equal Protection Clause. The club receives a state liquor license. ANALYSIS: Is there state action? Mere licensing/regulation is NOT enough. The liquor license doesn't make the state sufficiently entangled in the club's membership decisions. No public function (private clubs aren't traditionally government activities). RESULT: No state action. Constitutional claim fails. Plaintiff would need a civil rights statute (like Title II) instead. - Exam shortcut: Private actors need government involvement Sources: conlaw-equal-protection, conlaw-commerce-clause, conlaw-civil-rights-cases ## 2. Standing Requirements Three requirements: (1) INJURY IN FACT - concrete, particularized, actual or imminent (not speculative); (2) CAUSATION - injury traceable to defendant's conduct; (3) REDRESSABILITY - favorable decision would remedy harm. TAXPAYER STANDING is very limited - only for Establishment Clause challenges to Congressional spending. NO generalized grievances (everyone is hurt). Third-party standing generally not allowed unless close relationship + obstacle to suit. Organizations can sue if members would have standing, interests are germane, and individual participation not required. HYPO: Environmental group sues EPA claiming new regulations will harm the environment. No member has identified specific injury. ANALYSIS: (1) Injury in fact? NO - "environment will be harmed" is too general. Need specific, concrete injury to a MEMBER. (2) Must show a member uses specific land that will be affected. RESULT: No standing without identifying at least one member with concrete, particularized injury. The group should amend to include declarations from members who use specific affected areas. - Exam shortcut: Injury + causation + redressability Sources: conlaw-equal-protection, conlaw-commerce-clause, conlaw-civil-rights-cases ## 3. Dormant Commerce Clause When Congress hasn't acted, states CANNOT: (1) DISCRIMINATE against interstate commerce - facial discrimination is virtually per se invalid (strict scrutiny); (2) UNDULY BURDEN interstate commerce - even neutral laws struck if burden on commerce outweighs local benefits (Pike balancing). EXCEPTIONS: (1) Market participant exception - state acting as buyer/seller can favor locals; (2) Congressional authorization - Congress can permit discrimination; (3) Traditional government functions. Look for laws favoring in-state businesses, blocking out-of-state waste, or requiring local processing. HYPO: State X bans importing out-of-state garbage. State claims it's protecting health and environment. ANALYSIS: This facially discriminates against interstate commerce (only out-of-state garbage banned). Apply STRICT SCRUTINY. Is there a legitimate local purpose? Yes - environmental protection. Are there non-discriminatory alternatives? YES - could limit ALL garbage or use other environmental controls. RESULT: Law is UNCONSTITUTIONAL. Garbage is commerce. Can't block out-of-state products just because they're from elsewhere (Philadelphia v. New Jersey). - Exam shortcut: Facial discrimination = virtually per se invalid Sources: conlaw-equal-protection, conlaw-commerce-clause, conlaw-civil-rights-cases ## 4. Free Speech - Time/Place/Manner CONTENT-BASED restrictions get strict scrutiny (necessary for compelling interest). CONTENT-NEUTRAL restrictions (TPM) get intermediate scrutiny if: (1) Significant government interest; (2) Narrowly tailored (not least restrictive); (3) Leave open alternative channels. PUBLIC FORUMS (streets, parks): TPM rules apply. LIMITED PUBLIC FORUMS (schools for designated use): Can restrict by subject matter. NONPUBLIC FORUMS (jails, military bases): Only need be reasonable and viewpoint-neutral. PRIOR RESTRAINTS are presumptively invalid. Overbreadth allows facial challenge if substantial number of applications are unconstitutional. HYPO: City bans all leafleting on public sidewalks to reduce litter. ANALYSIS: Public sidewalks = traditional public forum. Is the ban content-neutral? YES - applies to all leaflets regardless of message. Apply INTERMEDIATE SCRUTINY: (1) Government interest? Reducing litter - significant. (2) Narrowly tailored? NO - a complete ban is too broad. Could require cleanup or use anti-littering laws. (3) Alternative channels? Must leave open ample alternatives. RESULT: Likely UNCONSTITUTIONAL - total ban not narrowly tailored when less restrictive options exist. - Exam shortcut: Content-neutral = intermediate scrutiny Sources: conlaw-equal-protection, conlaw-commerce-clause, conlaw-civil-rights-cases ## 5. Equal Protection Scrutiny Levels STRICT SCRUTINY (suspect classes/fundamental rights): Race, national origin, alienage (state). Must be necessary to achieve compelling interest. Applies to intentional discrimination only. INTERMEDIATE SCRUTINY: Gender, legitimacy. Must be substantially related to important interest. RATIONAL BASIS: Everything else (age, disability, wealth, sexual orientation for most purposes). Must be rationally related to legitimate interest - very deferential. NOTE: Alienage gets rational basis for federal laws (plenary immigration power) and for state laws involving self-government (voting, police, teachers). HYPO: State requires all police officers to be U.S. citizens. Non-citizen applicant challenges. ANALYSIS: Usually alienage gets STRICT SCRUTINY for state laws. BUT there's an exception for positions involving "self-government" and discretionary authority over citizens. Police officers exercise significant discretionary power (arrests, force). RESULT: Rational basis applies under the "political function" exception. Law upheld - state can reasonably require citizens for police. - Exam shortcut: Know triggers for each level Sources: conlaw-equal-protection, conlaw-commerce-clause, conlaw-civil-rights-cases ## Primary law and source anchors - **U.S. Constitution Amendment XIV, Section 1**: The Equal Protection Clause text used for scrutiny-level analysis. (https://constitution.congress.gov/constitution/amendment-14/) - **U.S. Constitution Article I, Section 8, Clause 3**: The Commerce Clause text underpinning congressional commerce power questions. (https://constitution.congress.gov/constitution/article-1/) - **The Civil Rights Cases, 109 U.S. 3 (1883)**: Foundational state-action decision distinguishing private from governmental conduct. (https://supreme.justia.com/cases/federal/us/109/3/) ## FAQ - **How should I use this Constitutional Law ranking page?**: Use it to decide review order, not as a substitute for practice. Start with the first two or three topics, then reinforce them with timed multiple-choice work. - **Does "most tested" mean the lower-ranked topics are unimportant?**: No. It means the higher-ranked topics deserve earlier and more frequent review because they trigger more downstream issues and more repeat appearances across mixed sets. ## Related pages - [Scrutiny Levels for Equal Protection and Fundamental Rights](https://www.barprepplay.com/deep-dives/constitutional-law/scrutiny-levels/) - [Constitutional Law One-Pager](https://www.barprepplay.com/one-pagers/constitutional-law/)
