Four months after the company came out of bankruptcy, Oklahoma City-based Chesapeake Energy announced that its general counsel and two other executives have stepped down, according to a filing with the U.S. Securities and Exchange Commission.

The move comes as part of a spate of in-house legal department moves in the energy industry, including the departures of in-house attorneys at CPS Energy and Anadarko Petroleum Corp. At CPS, the moves came as the company deals with extensive litigation, which its CEO said will cost $10 million in outside counsel spending, according to a recent report in the San Antonio Express-News.
