Subject matter JDX
generally
A federal court must have subject matter JDX in order to decide cases before it.
Federal question JDX
A federal court has SMJ under federal question JDX if the complaint alleges a claim that arises under federal law
well pleaded complaint rule
The federal question must be presented on the face of the plaintiff’s complaint. Raising a defense or filing a counterclaim under federal law does not trigger federal question JDX
Diversity JDX
A federal court has SMJ under diversity JDX if there is complete diversity and the amount in controversy exceeds $75,000
Complete diversity
Complete diversity is present if every plaintiff is a citizen of a different state than every defendant
AIC and injunctive relief
A claim for injunctive relief may be valued by the benefit to the plaintiff or the cost of compliance to the defendant
One P aggregating claims to meet AIC
Multiple Ps aggregating claims to meet AIC
If there are multiple plaintiffs, generally, each plaintiff’s claim must meet the amount in controversy requirement separately, unless supplemental JDX applies
Things a federal court never has JDX over
A federal court does NOT have diversity jurisdiction for probate actions and domestic relation matters (e.g., divorce, child support/custody, etc.)
Citizenship
general rule
The citizenship of each party to the action must be considered in order to decide whether complete diversity is present
citizenship of individuals
citizenship of corporations
Corporations hold dual citizenship for diversity purposes
- the state or country of incorporation; and
- the state or country of its principal place of business (i.e., the nerve center, usually where the corporate headquarters are located)
citizenship of unincorporated associations
unincorporated associations and partnerships are considered a citizen of every state in which its members are citizens
Diversity for class actions
generally
Supplemental JDX
generally
Supplemental JDX allows a federal court with valid SMJ over a case to hear additional claims which the court would not otherwise have JDX over if ALL the claims constitute the same case or controversy
same case or controversy
for supplemental JDX
Claims constitute the same case or controversy if they arise out of a common nucleus of operative fact (meaning they arise out of the same transaction or occurrence)
supplemental JDX in federal question cases
A federal court sitting in federal question JDX may hear a pendent state law claim under supplemental JDX if the state law claim arises out of the same transaction or occurrence as the federal law claim
Compulsory counterclaims, diversity, and supplemental JDX
Permissive counterclaims, diversity, and supplemental JDX
Crossclaims, diversity, and supplemental JDX
Collateral order doctrine

- that is separable from and collateral to the merits of the case
- involves a serious and unsettled legal question AND
- would be effectively unreviewable if the court waited until final judgment to hear the claim or issue
mandamus review
