Although a Hays County District Court ruled to dismiss Cause 20-2040; it appears a review of the 2015 Legislature sheds light upon the requirements to receive the annual supplement referenced in a San Marcos Corridor News Publishing
Specifically, the 2015 ENROLLED BILL REQUIRES the following:
There MUST NOT be a County Court at Law AND the Judge MUST preside over Class A and B misdemeanor cases, probate matters, guardianship matters, and matters of mental health.
Per the San Marcos Corridor news story, none of that seems to have occurred. Please reference their series of stories for more information on the matter.
