Facts of the case

In 1785, the Massachusetts legislature incorporated the Charles River Bridge Company to construct a bridge and collect tolls. In 1828, the legislature established the Warren Bridge Company to build a free bridge nearby. Unsurprisingly, the new bridge deprived the old one of traffic and tolls. The Charles River Bridge Company filed suit, claiming the legislature had defaulted on its initial contract.

Question

Did the legislature enter into an economic contract with the Charles River Bridge Company that was impaired by the second charter in violation of Article I Section 10 of the Constitution?
