The federal judge in the Hollis V. Holder case (Texas Form 1 machine gun case) has ordered oral arguments on the government's motion to dismiss, set for April 23rd. This seems to indicate that Hollis' arguments have some merit and she is interested in hearing them. At least, the federal government has to present their "A" game to get this case dismissed before trial.
If you want to see gun trusts be able to manufacture machine guns through a Form 1 application, consider donating to the Heller Foundation, which is supporting this lawsuit. https://hellerfoundation.org/
