What is the well-pleaded complaint rule?
(also known as the Mottley Rule)
P must state that D has already violated a federal law on the face of the complaint to qualify as federal question jurisdiction. Federal question cannot be asserted as a defense (by P or D) - the federal question issue must be asserted by P on the face of the complaint.
⚠️ Note: P can’t anticipate that D will violate a federal question in the future; the violation must have already occurred to satisfy the well-pleaded complaint rule.

supplemental jurisdiction
Power for courts to hear a claim that does not have SMJ as long as the claim is substantially related to one for which SMJ does exist.
If the court has federal question jurisdiction, how do you determine whether supplemental jurisdiction exists?
Ask: Do the claims arise from the same transaction or occurrence? (i.e. share a “common nucleus of operative fact”?)
If yes, supplemental jurisdiction likely exists.
If the anchor claim is based on diversity, how do you determine whether supplemental jurisdiction exists?
Ask:
If yes, then supplemental jurisdiction exists.
⚠️ Remember, this exception only applies when P brings a claim that would add the new party to the suit. The rule exists to prevent P’s from skirting the requirements of diversity jurisdiction by joining parties not originally named in the action.

removal jurisdiction
Allows federal courts to hear cases that are removed from state court to federal court in the same district where the suit is pending.
When can a case be removed to federal court? (generally)
When P could have filed original complaint in federal court.
⚠️ Federal court must have federal question, diversity, or supplemental jurisdiction over all claims
Which parties can seek to remove a case?
Defendants only. P’s can never seek to remove, even if the D’s filed a counterclaim.
What are the special requirements for removal based on federal question?
The well-pleaded complaint rule must be satisfied (i.e. the federal question must be presented on the face of the original complaint).
Hypo: P files complaint based on state law. D files answer asserting federal question and seeks to remove to federal court. Should removal be allowed?
No, because of the well-pleaded complaint rule. Federal question jurisdiction cannot be based on the answer - must be asserted on the face of the complaint.
When is removal based on diversity jurisdiction allowed?
