Separate from the Spruce mine litigation, the larger suit could be settled or go to trial starting Tuesday.
Haden is expected to rule today or Monday on how the case will go forward.
In March, Haden had issued a preliminary injunction that stopped the Corps from authorizing the mine under the nationwide permit.
Haden ruled that environmental groups had a strong legal argument that the mine needed a more detailed environmental review under an individual Corps permit.
The Corps said two weeks ago that it would review the mine under an individual permit application, a process that could take one or two years.
Last Friday, lawyers for Arch Coal unveiled a new permit revision to address some of Haden's objections. But if that proposal were approved immediately, the mine still could not start up without the Corps permit.
In court papers filed Thursday, company lawyers said the Corps told them two months ago that the agency was interested in withdrawing the permit.
Company lawyers urged Haden to stop the Corps from doing so.
"The Corps promised a [permit] to Hobet," company lawyers said. "Then, for no reason other than a fear of continued litigation, it revoked Hobet's authorization in clear violation of both its own regulations and [the law]."
Arch Coal has said it plans to lay off most of the 400 Dal-Tex miners by July 23 if a new permit is not approved.
