" A similar inspection right is usually available to unit holders and limited partners in a limited partnership ("LPs") and holders of interests in alternative entities such as limited liability companies ("LLC's")."
My thoughts are that what needs to be seen are TPLs' books. Unfortunately, I think that if the SEC can't get at them, a hired attorney stands a snowballs' chance in hell. That, my friends is reality. That was the design of the Joint Venture with a private entity.
If anyone proceeds with consulting with a legal advisor, that should be the first suspicion mentioned. PTSCs' books will reflect what TPL reported to them. IMO
