Leon County is suing the City of Tallahassee.
An injunctive relief has been filed regarding the city's annexation of the Weluanee Plantation.
The county says it did not receive enough time to review the annexation of the undeveloped property near I-10 on Highway 90.
The city adopted the annexation ordinance last month even with the county's objection.
Among county concerns are different development standards between the city and county and sewer impacts. In the complaint, the county is asking the courts to enter an injunction, and if the city pursues annexation again that the city engage in mediation with the county.
The city has 20 days to respond to the complaint and is reviewing the suit.
