The government always has standing for criminal cases (the only kind that involve jail) because the offense is against society. The families of a deceased person has standing to sue in a civil case. Any one who had a test run by the company has standing to sue as well, even if there was no harm - they did not receive the product that was advertised, namely a validated test.

I doubt this will result in jail time for the principles, but they should be expecting lawsuits over this.
