Constitutional law addresses the fundamental structure of government and the rights of individuals against government power. The field encompasses challenges to legislation, executive action, and government policies that allegedly violate constitutional provisions. Constitutional litigation shapes the boundaries of government authority and individual liberty.
Constitutional Framework
Separation of powers divides federal authority among legislative, executive, and judicial branches. Each branch has defined powers. Encroachment by one branch on another’s authority raises constitutional issues.
Federalism allocates power between federal and state governments. Federal power is limited to enumerated authorities. States retain police power over health, safety, and welfare.
Supremacy Clause makes federal law supreme over conflicting state law. Preemption analysis determines when federal law displaces state regulation.
Individual rights amendments limit government power. The Bill of Rights originally restrained only federal government. Incorporation doctrine applies most provisions to states through the Fourteenth Amendment.
First Amendment
Free speech protection extends to political speech, artistic expression, and commercial speech with varying levels of protection. Government cannot restrict speech based on viewpoint.
Content-based restrictions face strict scrutiny. The government must show the restriction is necessary to achieve a compelling interest. Few restrictions survive.
Content-neutral restrictions face intermediate scrutiny. Time, place, and manner regulations must be narrowly tailored to significant interests and leave open alternative channels.
Prior restraints are presumptively unconstitutional. Government generally cannot prevent speech before it occurs. Subsequent punishment is preferred to prior censorship.
Free exercise of religion protects religious practice from government interference. Neutral laws of general applicability receive rational basis review. Laws targeting religion face strict scrutiny.
Establishment Clause prohibits government endorsement of religion. Analysis has shifted from Lemon test toward historical practices approach.
Fourth Amendment
Unreasonable searches and seizures are prohibited. The amendment protects reasonable expectations of privacy against government intrusion.
Warrant requirement mandates judicial approval for most searches. Warrants require probable cause and particularity.
Exceptions to warrant requirement include consent, exigent circumstances, search incident to arrest, automobile exception, and plain view.
Exclusionary rule bars use of evidence obtained through unconstitutional searches. Good faith exception allows use when officers reasonably relied on defective warrants.
Third-party doctrine holds that information voluntarily shared with third parties loses Fourth Amendment protection. The doctrine’s scope in digital age is contested.
Fifth Amendment
Self-incrimination privilege protects against compelled testimonial self-incrimination. Miranda warnings advise of the right during custodial interrogation.
Due process requires fair procedures before deprivation of life, liberty, or property. Procedural due process mandates notice and opportunity to be heard.
Substantive due process protects fundamental rights from government interference regardless of process. Strict scrutiny applies to infringement of fundamental rights.
Takings Clause requires just compensation when government takes private property for public use. Regulatory takings occur when regulation goes too far.
Fourteenth Amendment
Equal protection prohibits discriminatory government action. Suspect classifications based on race and national origin receive strict scrutiny.
Quasi-suspect classifications based on gender receive intermediate scrutiny. Government must show important interest and substantially related means.
Rational basis review applies to most classifications. Government action must be rationally related to legitimate purpose.
State action requirement limits Fourteenth Amendment to government conduct. Private discrimination is not directly covered.
Incorporation applies Bill of Rights protections to states. Most but not all provisions have been incorporated.
Standing and Justiciability
Standing requires injury in fact, causation, and redressability. Plaintiffs must show concrete harm from challenged action.
Ripeness prevents premature adjudication. Claims must be fit for decision with hardship from withholding review.
Mootness bars claims where controversy no longer exists. Capable of repetition yet evading review exception allows some moot claims.
Political question doctrine makes some issues nonjusticiable. Courts decline to decide matters committed to other branches.
Constitutional Litigation
Facial challenges attack laws as unconstitutional in all applications. The challenger must show no set of circumstances exists where the law would be valid.
As-applied challenges attack laws as unconstitutional in specific applications. The law may be valid generally but unconstitutional in particular circumstances.
Preliminary injunctions can block enforcement pending litigation. Likelihood of success on the merits is key factor.
Section 1983 provides damages remedy for constitutional violations by state actors. Bivens provides limited federal counterpart.
Attorney fees under Section 1988 allow prevailing plaintiffs to recover fees. Fee shifting encourages constitutional litigation.
For Service Members
Constitutional rights of service members are modified by military necessity. Courts give deference to military judgment on internal affairs.
First Amendment rights are limited in military context. Speech that undermines good order and discipline can be punished. Political activity restrictions apply.
Fourth Amendment applies differently on military installations. Consent to search may be broader. Command-directed searches have different requirements than civilian warrants.
Fifth Amendment UCMJ rights include Article 31 warnings analogous to Miranda. Self-incrimination protection applies in military justice.
Due process in military administrative actions requires appropriate procedures. Board hearings, separation procedures, and adverse actions must meet due process standards.
Equal protection applies to military policies. Gender-based restrictions on combat roles were changed partly due to equal protection concerns.
Court-martial procedures must satisfy constitutional requirements. Right to counsel, confrontation, and other protections apply.
Military deference doctrine limits judicial review of military decisions. Courts hesitate to second-guess military judgment on personnel and operational matters.
A military attorney understands how constitutional protections are modified in military context, what rights service members retain, and how to assert constitutional claims within military constraints.
