Putting somebody in
charge of a job, when they have a conflict of interest. Often used to refer to industry "self-regulation" or to putting an industry insider on the board that regulates that industry, e.g., appointing an executive of Comcast as chairman of the
FCC.
Can also refer to a similar problem in private industry, e.g., putting the
manager of a failed project in charge of the investigation into why the project failed.
