It looks like the J4 filed declaratory judgment cases against PTSC, et. al., when TPL refiled in Texas. Those DJ cases were filed November 28, 2005. The Dec 6th motion appears to be an attempt to get all those DJ cases (as they call `em in the complaint) deemed related to the old Calif case that PTSC withdrew from.
So, the Dec 6th motion seems to be asking Judge Armstrong to declare the DJ cases related to the old PTSC case. If that were to happen, then it would seem like the old PTSC case (which TPL said it would take over, substituting itself as plaintiff) could be, for lack of better nomenclature, revived. At that point, somebody -- you got me as to whom -- has to determine which procedure/docket takes priority: Texas or Calif.
