Whether ICS's state-court administrative-review complaints were removable when they included federal constitutional claims.
Holding
Yes. ICS's federal constitutional claims arose under federal law and supplied original federal-question jurisdiction, making the actions removable under 28 U.S.C. § 1441(a).
Reasoning
Removal is proper when the action could originally have been filed in federal district court. Under the well-pleaded-complaint rule, a case arises under federal law when the plaintiff's own complaint raises a federal issue; ICS did exactly that by alleging that Chicago's landmark ordinances and the Commission's procedures violated the Federal Constitution.
The fact that ICS presented its constitutional arguments through a state-created administrative-review procedure did not eliminate federal-question jurisdiction. A state-law cause of action may arise under federal law when the right to relief necessarily depends on resolving a substantial federal question, and ICS's facial and as-applied constitutional claims turned on federal law.
ICS therefore could not preserve a state forum merely by choosing a state procedural vehicle for its federal claims. As master of its complaint, it could choose what claims to bring, but once it pleaded claims arising under federal law, Chicago could remove the action.
