The U.S. Court of Appeals for the Second Circuit decision issued Friday to reject a lawsuit by the Constitution Pipeline challenging New York state’s decision not to grant the necessary water permit to build the 121-mile natural gas pipeline doesn’t mark the end of the project, the builders said.

In an emailed response to the New York Law Journal Monday, Constitution Pipeline, a partnership among Cabot Oil & Gas Corp.; Oklahoma-based energy company Williams Cos.; Piedmont Natural Gas and WGL Holdings, said the company was “weighing all options” on how to proceed with the project.
