There's a catch 22.
The Institute for Justice (IJ) is a 501C(3) non-profit, non-political law firm aimed at providing pro bono legal support for small mom'n'pop businesses like Schott's Supermarket. IJ exists only on tax deductible donations. Think IRS/TEA Party.
The alleged "crime" was depositing their receipts in a bank account. The state called it "laundering". Never proven, but the state kept the money anyway because of a poorly written law. And the state will use the money to fight the Schotts.
Enter IJ to defend the Schotts. If IJ defends the Schotts against the law, IJ can lose it's 501C(3) status and no longer collect donations because it becomes involved in a political activity.
So IJ has joined the Schotts in their suit as a co-defendant against the state.
We'll see what develops.
