A bit of additional context: the dispute stemmed from the fact that Nutt was asked to give testimony about stormwater management systems, not chemical engineering. Unlike chemical engineering, this subject is within the purview of the Board, so they believed that their ban on unlicensed expert witness testimony should apply.

From what I can see, the court here ruled that the ban itself is unconstitutional, so not only do they need to leave Nutt alone, but they're not allowed to enforce the ban on expert engineering reports at all going forward.
