The lawsuit includes email exchanges the company claims show Chesapeake and Encana executives discussing which counties each company would bid on.
After nine days of email exchanges, Chesapeake Vice President Doug Jacobson told Encana vice president John Schopp “we are basically good with the county split you've proposed,” and urged quick action to keep “acreage prices from continuing to push up,” according to the lawsuit.
In another email, Chesapeake CEO Aubrey McClendon told top Chesapeake and Encana executives, it “looks like NorthStar wants us to bid against each other next week, let's decide who should handle that one.”
The U.S. Justice Department and Michigan's attorney general also are investigating Chesapeake and Encana for possible antitrust violations.
