A federal judge has ordered that $35,000 be paid to the Coastal Conservation League for money it spent on lawyer fees.
The CCL asked the court to be reimbursed for nearly $53,000 it spent to defend itself against legal action brought by Woodale Partnership.
Senior U.S. District Judge Margaret Seymour issued her ruling Monday.
The decision is the latest development in litigation that began when Woodale Partnership filed suit over Charleston's 2006 rezoning of hundreds of acres on Johns Island.
The partnership sued the CCL, the City of Charleston and Johns Island Growth Management Committee, alleging a conspiracy to prevent their project on hundreds of acres near River and Plow Ground roads. Woodale alleged that the city, the CCL and JIGMC had acted to violate its property rights.
In 2010, Seymour ruled in a summary judgment in favor of the CCL and the city. She dismissed JIGMC as a defendant.
Last April, Charleston City Council approved the rezoning sought by Woodale for a mix of homes, commercial and warehouse space on Johns Island.
In its unanimous vote, the City Council reversed a 6-0 Planning Commission recommendation to turn down the rezoning request.
The property was zoned for one unit per 1.5 acres. It was rezoned to allow for a 462-acre Planned Unit Development with a greater density.
At the time, some islanders expressed fears about noise and traffic being added to the mostly rural areas around the project.
