It's the Howard County Appraisers versus their biggest taxpayer.
Attorneys for the Alon refinery met with the County in a 20 minute pre-trial hearing on Thursday morning.
The appraisal district valued the refinery at about 300 million dollars, but Alon believes they miscalculated their worth to the tune of tens of millions of dollars.
But it's the taxpayers that could take a hit.
Alon has agreed to pay taxes on a small amount of their value until the case is resolved.
In the meantime, the Commissioners Court raised the tax rate to make up the difference.
The trial is set for August 18th.
