USARK just posted this on their facebook page:
Lawsuit Update: Today at 2:00 PM began a 3-hour hearing regarding USARK's federal lawsuit. Judge Moss did not make a ruling from the bench on USARK's Temporary Restraining Order (TRO) or Preliminary Injunction. Tomorrow a schedule will be set for additional filings from both parties.
The effective date remains April 9. In 21 days from tomorrow (4/8/15), we should have a decision from Judge Moss if the Court will issue a cessation of enforcement and allow an extension of the effective date. If USARK's TRO is decided upon favorably and the effective date is extended, then interstate transportation and importation (or possibly only interstate transportation) can continue as usual. It will likely be months before a ruling is made on the lawsuit.
Additionally, Judge Moss passed a motion allowing the filing of USARK's second amended complaint. We'll provide additional information soon.
