Preserve Lexington filed suit on Tuesday seeking a temporary injunction to prevent the city from issuing demolition permits for eight buildings in the Courthouse Area Overlay Zone.
Other defendants are the Courthouse Area Design Review Board, CentrePointe LLC and owners of existing buildings on a block bound by Main, Vine, Upper and Limestone streets.
Last week, the Review Board voted to allow the developers of CentrePointe, a proposed $250 million tower, to raze the buildings. It gave permission for construction of a 35-story hotel, condominium and retail high rise.
Preserve Lexington is appealing that decision to the Planning Commission. The Planning Commission has 90 days to act. Preservationists say they filed suit because there is ambiguity in the law, which might permit the buildings to be torn down while their appeal is pending.
A hearing is scheduled for 8:45 a.m. Wednesday in Circuit Court before Judge Pamela Goodwine.
