I have not been following the ongoing status of the pending lawsuits and appeals. However, while some states did get a favorable ruling----one, I believe they were either stays, temporary injunctions, etc.; and two, they were prior to the last legislative revision. Since the FTC (and Congress) revised the legislation and governing authority of HISA, I think that changes and impacts the rulings that the states received.
All things considered, in the end, I do not see a state deciding "we don't want it" and "we won't go along"----because HISA will have the authority and right to enforce it. There are numerous enforcement actions they can take. Didn't they already do this in Texas? I believe Texas received a favorable ruling, but didn't they get their simulcasting signal shut down or something? I don't remember the details. At the end of the day, I think HISA will stand, and eventually, the harness industry will have little to no choice but to play ball.
