State Auditor Jim Zeigler is asking to join an ongoing lawsuit over the use of oil spill settlement funds to build a beachfront hotel and conference center at Gulf State Park. Zeigler Tuesday filed the motion to intervene in the civil lawsuit in Montgomery circuit court. Former Conservation Commissioner Charley Grimsley, a longtime opponent of the project, filed a lawsuit in April against Gov. Robert Bentley challenging the use of the money for the project. Bentley has moved to dismiss the lawsuit, arguing that Grimsley does not have a basis or standing to sue.
