The EPA is under investigation for a practice called Sue and Settle. Environmentalists in government and private organizations have found ways to create new regulations by fashioning lawsuits tailored to have courts institute policy changes. Both parties involved in the lawsuits secretly decide in advance what the outcome will be and how much taxpayer money will be transferred to the environmental group in the settlement. In other words, they are exploiting the courts to change laws, and in the process, helping to fund radical environmental groups without legislative or taxpayer consent. Millions of taxpayer dollars have been given to these groups.
