Why it matters
This is the foundational American statement of the public trust doctrine, and it is one of the American authorities the Supreme Court of India drew on in M.C. Mehta v Kamal Nath (the Span Motels case) when it declared that the State holds natural resources in trust for the public. If you are asked where the Indian doctrine comes from, this case is the root.
Its lesson is simple and powerful: the State's title to land under navigable waters is not ordinary ownership. It is held in trust for the people, and a legislature cannot give the whole of it away to a private company. If it tries, the grant can be revoked.
Facts
In 1869 the Illinois legislature passed the Lakefront Act. Section 3 granted "in fee" to the Illinois Central Railroad Company the State's right and title to the submerged lands forming the bed of Lake Michigan east of the company's tracks and breakwater for a distance of one mile — over 1,000 acres, which the Court described as more than three times the area of Chicago's outer harbour. The company was not to sell the fee, and was to pay the State a percentage of receipts from the lands.
The Court noted that the bill, as first introduced, was meant to cede these lands to the City of Chicago; during its passage it was changed to cede them to the railroad instead.
On 15 April 1873 the legislature repealed the 1869 Act. The State then filed a bill seeking a decree confirming its title to the lake bed and its exclusive right to develop the harbour, the removal of the company's unlawful structures, and an injunction against further ones. The City of Chicago filed a cross-bill. The Circuit Court decided largely against the railroad, which appealed.
Issues
The Court framed the central question itself: "whether the legislature was competent to thus deprive the state of its ownership of the submerged lands in the harbor of Chicago, and of the consequent control of its waters -- or in other words, whether the railroad corporation can hold the lands and control the waters by the grant against any future exercise of power over them by the state."
Subsidiary questions concerned the railroad's rights over the land already reclaimed for its tracks, and whether its piers extended beyond the point of navigability.
Held
The decree below was affirmed, with modifications concerning certain piers, which were sent back for inquiry into whether they extended beyond the point of practical navigability.
The nature of the State's title
The State holds the lake bed as it holds soil under tidewater at common law, but "it is a title different in character from that which the state holds in lands intended for sale." It is "a title held in trust for the people of the state, that they may enjoy the navigation of the waters, carry on commerce over them, and have liberty of fishing therein, freed from the obstruction or interference of private parties."
What the State may and may not grant
The State may grant parcels for wharves, docks and piers in aid of commerce, or parcels whose occupation does not substantially impair the public interest in what remains. But that is different from "the abdication of the general control of the state over lands under the" navigable waters of an entire harbour, bay, sea or lake. "Such abdication is not consistent with the exercise of that trust which requires the government of the state to preserve such waters for the use of the public."
"The trust devolving upon the state for the public, and which can only be discharged by the management and control of property in which the public has an interest, cannot be relinquished by a transfer of the property."
The Court compared the trust to the State's police powers: "The state can no more abdicate its trust over property in which the whole people are interested, like navigable waters and soils under them, so as to leave them entirely under the use and control of private parties", except for the parcels just mentioned, than it can abdicate its police powers.
The grant was revocable
"Any grant of the kind is necessarily revocable, and the exercise of the trust by which the property was held by the state can be resumed at any time." The State may have to pay for improvements made under the grant, but its power to resume the trust is "incontrovertible". The railroad's position "would place every harbor in the country at the mercy of a majority of the legislature of the state in which the harbor is situated."
"The trust with which they are held therefore is governmental, and cannot be alienated", save for the permitted parcels. Each legislature must exercise the State's power under the trust in its own time; "The legislature could not give away nor sell the discretion of its successors".
The holding
"We hold, therefore, that any attempted cession of the ownership and control of the state in and over the submerged lands in Lake Michigan by the Act of April 16, 1869, was inoperative to affect, modify, or in any respect to control the sovereignty and dominion of the state over the lands, or its ownership thereof, and that any such attempted operation of the act was annulled by the repealing Act of April 15, 1873, which to that extent was valid and effective. There can be no irrepealable contract in a conveyance of property by a grantor in disregard of a public trust, under which he was bound to hold and manage it."
The railroad kept the land it had lawfully reclaimed for its tracks, but only for railroad purposes: it never acquired an absolute fee in that land with a right to use it for any other purpose.
Ratio
A State holds the land under navigable waters in trust for the public — for navigation, commerce and fishing. It may grant particular parcels that serve those purposes or that can be disposed of without substantially impairing the public interest in what remains, but it cannot abdicate its control over the whole of such a resource in favour of a private party. Any such grant is revocable, and no irrepealable contract can arise from a conveyance made in disregard of the public trust.
Exam use
- Origin of the Indian doctrine: in any answer on the public trust doctrine, cite Illinois Central as the classic American authority relied on in M.C. Mehta v Kamal Nath. State clearly that it is a United States Supreme Court decision — persuasive, not binding, in India.
- Key idea to reproduce: the State's title is "a title held in trust for the people of the state"; a grant of the whole resource to a private party is an abdication that the trust forbids, and it is revocable.
- Problem question: a State leases an entire riverbank, lake or forest to a private resort or company for its exclusive use. Apply Illinois Central: the State may grant parcels that serve or do not impair public use, but not surrender control of the resource as a whole.
- Critical question: Does the public trust doctrine undermine the security of State grants? Use the dissent: the proper route to undo a regretted grant is acquisition with compensation, not bare revocation.
