Illinois Central Railroad v. Illinois (1892)
The Illinois legislature had granted the Illinois Central Railroad title to a large stretch of submerged land along Chicago's lakefront. The U.S. Supreme Court held the grant invalid, ruling that the state holds submerged lands in trust for the public and cannot give them away wholesale.
The railroad lost its claim to the lakebed.
The decision became the foundation of the public trust doctrine in U.S. law, cited when governments try to transfer waterfront to private owners.
It is the clearest precedent for the idea JABBEM is pressing: that a state's ownership of the shore comes with an obligation to keep it publicly usable.
