I am not a lawyer, nor have I ever played one on TV. However, in my opinion they may be liable for a lot of things. Back taxes could certainly be one of them. Probably court costs. Maybe the cost of their last minute vote to cover their behinds as well, which by my estimation cost about $4-5k for materials, printing and mailing. I also wonder if criminal charges could be in their future. Only time will tell.
The ironic thing as I see it, is if they had just held elections as some of us have asked about for years, they'd probably still hold their positions, we wouldn't be having this conversation and GRGR would still be grinding along with minimal membership and dwindling relevance with the SC legislature.
Hopefully after this wake up call, GRGR can come back as a strong and vital organization. Unfortunately I think at this point the "brand" may be damaged beyond repair.
