General Motors (GM) (defendant) ran a manufacturing plant in the town of Ypsilanti (plaintiff), called the Willow Run plant. GM sought a tax abatement from Ypsilanti in order to make improvements at the plant. Ypsilanti granted two tax abatements under Michigan statutes providing for them. At a public meeting regarding the abatements, GM’s plant manager stated that the completed project would allow Willow Run to continue production and that continuous employment could be maintained. GM later decided to move its manufacturing from the Willow Run plant to another location outside of Ypsilanti. Ypsilanti brought suit alleging breach of contract, promissory estoppel, unjust enrichment, and misrepresentation.
