Teesworks will not appeal against High Court port ruling
PD Ports, which operates Teesport, said the Court of Appeal largely refused Teesworks permission to appeal, except on pedestrian access along South Gare Road.
STDC said it had never intended to appeal against the High Court ruling, which it again confirmed during a recent board meeting.
Tees Valley Mayor Ben Houchen said: "Just to be clear from an STDC point of view, there's no additional financial liability at all on what Teesworks decide to do themselves.
"But I believe that legal action's been discontinued."
