Jeff Holmstead, perhaps the nation's prime example of a revolving door lobbyist, was dismissed by a federal judge as an expert witness in a lawsuit brought by the U.S. Environmental Protection Agency against Ameren Missouri, a coal burning utility.

In an ongoing case, the EPA has charged Ameren with violating the Clean Air Act by not installing appropriate pollution controls at one of its coal plants. The Sierra Club has since sued Ameren, "alleging 7,880 air quality violations at three coal-burning power plants since 2009," according to the St. Louis Post-Dispatch.

Judge Rodney Sippel granted U.S. Justice Department's request to remove Holmstead as a witness, confirming that the lobbyist's history at U.S. EPA posed "multiple conflicts of interest." Here's the judge's motion to dismiss Jeffrey Holmstead, citing Holmstead's use of his EPA experience to undermine EPA's pollution enforcement actions (emphases added):

"Mr. Holmstead’s legal opinions are irrelevant, speculative, and inadmissible." [...] "By his own description, Mr. Holmstead’s testimony relies on his recollection of EPA “internal meetings” that he says are relevant to the issues to be tried in this action. Such internal communications are privileged and confidential and Mr. Holmstead may not rely on his recollection of them to testify against EPA. Moreover, Mr. Holmstead received other privileged information concerning the issues about which he now seeks to testify on behalf of Ameren, and participated in power-plants enforcement cases related to this one while at EPA. Before he left EPA, he even personally provided a declaration for EPA that is at issue in this and other related power-plants enforcement cases asserting privilege claims on behalf of EPA over documents that are relevant to the opinions he now seeks to offer. Yet he now seeks to change sides and testify against EPA. Moreover, he was assisted in the preparation of his report by another former EPA attorney who was involved in the early stages of the investigation that ultimately led to the filing of this case. For the reasons discussed in the accompanying Memorandum, Mr. Holmstead should not be allowed to testify in this matter due to his multiple conflicts of interest.

This is a notable blow to Mr. Holmstead's credibility, who touts his time at EPA to obscure his lobbying to protect polluters from public accountability. An anonymous source "familiar" with this case, likely one of Holmstead's colleagues at Bracewell & Guiliani, has been attempting to spin this embarrassing dismissal to reporters at Bloomberg and E&E Publishing. Ameren claims the judge has no proof that Holmstead would use privileged information, ignoring the judge's reference that Holmstead himself said he would use information from "internal meetings" during his time at EPA.

Jeffrey R. Holmstead, a partner at Bracewell & Guiliani who represents coal mining and utility clients like Arch Coal, Duke Energy and Southern Company, spent four years as EPA's assistant administrator for Air and Radiation under President George W. Bush. His career is a dirty legacy of work against the public interest.

Holmstead's tenure at EPA was controversial all the way from his appointment, protested by U.S. Senators for his previous lobbying for coal companies, until his departure. He was caught censoring science within his office and single-handedly derailed a mercury pollution regulation that would have prevented thousands of premature deaths every year. Holmstead's interference blocked mercury pollution controls at U.S. coal plants for eight full years, as Greenpeace has documented, and confronted Holmstead directly for explanation.

While Ameren from his former government employer, Jeff Holmstead has been working to undermine the nation's first ever attempt to limit carbon pollution from U.S. power plants, misleading the public with fears that these rules will increase their utility bills. Holmstead has been repeatedly fact-checked on his conflation of electricity rates with people's bills, ignoring how energy efficiency measures are expected to lower bills over the long term, and also ignoring the immense costs of coal pollution to the public. Holmstead's office runs a front group called the Electric Reliability Coordinating Council (ERCC) to advocate for these polluters against climate and clean air rules, and representing ERCC, he has personally accompanied an Arch Coal lobbyist to the White House to undermine climate regulations.

Again, Greenpeace has directly sought answers from Mr. Holmstead on why he has dedicated his life to protecting companies that not only undermine science, but quite literally kill people as a regular part of their business operations:

It's nice to see a judge finally toss the fox out of the hen house. Jeff Holmstead says what he's paid to, and his clients make that money by polluting for free.
