Hunting with dogs has been under attack for years by anti-hunting activists who see it as low hanging fruit. It is a strategic means to an end. You win over emotional people, the voting public who will view chasing poor little fuzzy animals as cruel, put an end to this form of hunting, and then work your way up the hunting ladder.
Even if they are not able to legally put an end to it, their efforts have been already been successful in my opinion when it comes to having a negative impact on hunting with dogs. It's a very common complaint that land access has become much more difficult, with landowners either viewing it negatively, worries over liability, or just not wanting the perceived hassle of hunters and their dogs on their property.
While I don't have beagles now, I did for decades. And, as a landowner myself, I much more welcome hunters and their handlers on my property with my permission, than the random neighborhood "pets" chasing deer past me while I'm on stand.
