I am doubtful that litigation would be successful in this case, here locally the damn GSF seem to show up in pretty much every water hole that may or may not have even been stocked, kind of like mud cats, No idea how they get in there but they do.
My pond is loaded with the darn things, GSF, and I never stocked any, I can see a few slipping through but definitely not many, but they are everywhere now in just a few yrs.
