Once triggered, the government must demonstrate that denying the exemption serves a compelling interest and is the least restrictive means of achieving it.

Exceptions from generally applicable laws granted to accommodate religious practices. The Free Exercise Clause does not require such exemptions when a neutral law incidentally burdens religious conduct, but the presence of discretionary secular exemptions renders the law not generally applicable and triggers strict scrutiny.

Such classifications trigger strict scrutiny and cannot be justified by fiscal concerns or a desire to deter migration of indigent persons.

An entitlement of a nonparty to join an existing federal civil action on timely motion when a federal statute confers an unconditional right to intervene.

A constitutional protection under the Second Amendment that safeguards an individual's ability to possess and use firearms for lawful purposes such as self-defense within the home.

A Sixth Amendment guarantee that protects an accused person against undue delay between accusation and trial. Courts determine whether the right has been violated by balancing the length of the delay, the reason for the delay, the defendant's assertion of the right, and prejudice to the defendant. No single factor is necessary or sufficient.

A right that permits a party to end an agreement, estate, or other legal relationship upon the occurrence of specified conditions or breach by the other party. The remedy requires the holder to take affirmative steps such as vacating the premises or providing notice to effect termination. It is distinct from rescission because it responds to a breach arising under the contract itself rather than an independent duty.

A fundamental constitutional right protecting the freedom of individuals to move freely between states. The right bars states from imposing durational residency requirements that deter migration of indigent persons or penalize new residents by withholding benefits available to longer-term residents. A state's interest in protecting its treasury does not justify such burdens.

A constitutional protection that entitles a defendant in a serious criminal case or a party in a civil action at common law to have factual issues decided by a jury rather than solely by a judge. The right attaches when the offense is serious or the claim seeks legal relief such as damages exceeding the jurisdictional threshold.

A buyer's revocation of acceptance of goods whose nonconformity substantially impairs their value to the buyer. Revocation is available when the buyer accepted on the reasonable assumption that the nonconformity would be cured and it was not seasonably cured or when acceptance was reasonably induced by the difficulty of discovery before acceptance or by the seller's assurances. The revocation must occur within a reasonable time after discovery and before any substantial change in the goods not caused by their own defects and must be accompanied by notice to the seller.

A legal right permitting one party to deduct amounts owed to it from amounts it owes another party, thereby netting mutual obligations without separate payment.

A right allowing one party to deduct an amount owed by the other from a sum the first party owes, thereby satisfying both obligations to the extent of the smaller debt.

It prevents the inefficiency of requiring each party to pay the full amount owed before collecting what is due in return.

An equitable right by which a party who fully performs another's secured obligation steps into the creditor's position against the primary obligor. The right prevents unjust enrichment and preserves the underlying claim and any security to the extent of the payment made.

Divorce or other specified events may sever the right and convert the ownership into a tenancy in common.

A fundamental liberty interest protected under the Due Process Clause of the Fourteenth Amendment that encompasses the decision whether to have biological children.

A rule that assigns responsibility for damage to or destruction of property to one of the parties to a contract for its sale before title or possession passes. Under the majority approach in land sales, once a binding contract is formed equity treats the buyer as owner of the land so the risk of loss from casualty passes to the buyer at contract formation even though legal title remains with the seller. The buyer must therefore pay the full price and cannot rescind or demand a reduction merely because improvements are destroyed before closing.

The government bears the burden of making an individualized showing of this fit.

A federal procedural rule requiring every pleading, written motion, and other paper filed in federal court to be signed by at least one attorney of record. The signature certifies that the paper is not presented for an improper purpose, that legal contentions are warranted by existing law or a nonfrivolous argument for change, and that factual contentions have evidentiary support or are identified as based on belief or lack of information. Violation after notice and opportunity to respond may result in sanctions against the attorney, law firm, or party responsible.

A court-imposed penalty for an attorney's or party's violation of the certification requirements in Federal Rule of Civil Procedure 11(b) when presenting pleadings or other papers.

A defense available to a defendant asserting that the plaintiff failed to effect service of the summons and complaint in the manner required by Rule 4. The defense focuses on defects in the manner or method of delivery rather than defects in the form of the summons itself.

A defense asserting that the plaintiff's complaint fails to state a claim upon which relief can be granted. The court accepts all well-pleaded factual allegations as true and draws all reasonable inferences in the plaintiff's favor. If those facts do not plausibly entitle the plaintiff to relief, the claim is dismissed without reaching the merits.

A procedural device allowing a defendant to seek dismissal of a complaint that fails to state a claim upon which relief can be granted. Courts disregard conclusory allegations and require well-pleaded facts that make the claim plausible rather than merely possible.

The court must also consider whether intervention will unduly delay or prejudice the original parties.
