Mr Dunlop resisted all eight grounds on their merits but his primary submission on Grounds 1-5 was that they have already been considered and resolved in the High Court by the Deputy Judge in the second set of judicial review proceedings. As I have mentioned, the target of the first five grounds of appeal is the Tribunal’s ruling on abuse of process dated 18 July 2023. Mr Dunlop submitted in writing and orally that Grounds 1-5 should not be entertained or given substantive consideration because principles of res judicata, cause of action estoppel or abuse of process applied. I shall therefore consider questions of res judicata at this juncture.
