Proprietors of the Charles River Bridge v. Proprietors of the Warren Bridge
The Supreme Court ruled that Massachusetts did not break any contract when it chartered the free Warren Bridge next to the older, toll-charging Charles River Bridge, even though the new bridge destroyed the older company's business.
The decision held that corporate charters granted by a state are read narrowly, so companies cannot claim exclusive rights or monopolies the charter's words don't actually spell out, clearing the way for states to authorize new roads, bridges, and railroads even when they compete with earlier ventures.
“In charters of- this description, no rights are taken from the public, or given to the corporation, beyond those which the words of the charter, by their natural and proper construction, purport to convey.”
States the rule that corporate charters are read narrowly, with nothing granted by implication.
How it got here: The Massachusetts high court, evenly divided, entered a pro forma decree dismissing the bridge company's suit so the case could be appealed to the U.S. Supreme Court.
The Case in Depth
What happened
In 1785 Massachusetts chartered the Charles River Bridge Company to build a toll bridge between Boston and Charlestown, replacing an old ferry. The company paid Harvard College an annuity and collected tolls for decades. In 1828 the legislature chartered a second company to build the nearby Warren Bridge, which was to become free after its costs were repaid. Once free, it drew away nearly all the Charles River Bridge's paying travelers, destroying the value of its franchise.
The question before the Court
When Massachusetts chartered a new, competing bridge that ruined the toll income of an older bridge company, did that break any promise the state had made to the older company?
Why it matters
The ruling meant investors in bridges, turnpikes, canals, and later railroads could not assume their charters gave them protection from competition unless the charter said so explicitly. This gave state legislatures freer rein to approve new infrastructure and technology even when it undercut existing businesses, encouraging the rapid buildout of transportation networks in 19th-century America.
What changes now
This was a final merits decision resolving the entire dispute; the Massachusetts court's dismissal of the bridge company's suit stood, and the Warren Bridge remained free and open. The ruling set a lasting rule for how American courts would read corporate charters going forward, denying implied exclusive rights unless a charter's words plainly granted them, which shaped later disputes over turnpikes, canals, and railroads.
What this does not decide
The Court did not decide the extent of Harvard College's original ferry rights or whether those rights had ever passed to the bridge company, finding it unnecessary to resolve those questions. It also did not rule that states could never grant exclusive franchises — only that this particular charter's silence could not be read to create one.
Concurrences and dissents
Concurrence — Justice McLean
Justice McLean agreed the bill should be dismissed but for a different reason: he believed the Court lacked jurisdiction because the suit was effectively against the state of Massachusetts itself, which could not be sued. He stated plainly that he believed the merits actually favored the bridge company's claim of an implied exclusive franchise, but concluded the Supreme Court had no power to decide the contract question at all in this posture.
Dissent — Justice Story
“It would be to the dishonor of the government, that it should pocket a fair consideration, and then quibble as to the obscurities and implications of its own contract.”Story's argument that the state should not evade the fair implications of a charter it was paid for.
Justice Story argued the charter necessarily implied a promise that the state would not destroy the bridge company's tolls by chartering a ruinous rival, drawing heavily on English common-law treatment of ferries, markets, and fairs as exclusive within a reasonable distance. He would have held the Warren Bridge charter unconstitutional as impairing the earlier contract and reversed the Massachusetts court's decree.
How the Court got there
The legal reasoning, step by step
- The Court applied the established rule that grants of public franchises to private corporations are construed strictly against the corporation and in favor of the public, so that any ambiguity is resolved against the company claiming the privilege.
- Because the plaintiffs could win only by showing a contract, not merely by showing that a later law divested a vested right, the Court asked whether the 1785 and 1792 charters contained any express promise that no other bridge would ever be built nearby.
- Reading the charter's actual text, the Court found no words granting an exclusive line of travel, no promise against future competition, and no language barring a second bridge — only the power to build the bridge and collect specified tolls.
- Relying on its recent ruling in Providence Bank v. Billings, the Court reasoned that just as a bank charter does not imply a promise never to be taxed, a bridge charter does not imply a promise never to face a competing bridge, because such surrenders of state power are never to be presumed.
- The Court further noted that the very same 1792 law that extended the company's charter also chartered a competing West Boston Bridge, showing the legislature never believed it had given up the power to approve rival crossings.
- Because no express contract term was broken, the Warren Bridge charter did not impair the obligation of any contract, so there was no violation of the Constitution's protection against state laws impairing contracts.
