administrative tribunal Act

"the chairman, vice chairmanor any other member shal not be removed from his office except by an order made by thePresidenton the ground of proved misbehaviour or in capacity after an enquiry  made by Judge of Supreme court ."a chairman may be an ex high court judge.but here system differs so far procedure is concerned.High Court is not the Appeal court against the order or judgment passed by the Tribunal such as cat or sat etc.though in true sense it exerts the same power.High Court is the scrutiny authority.scrutiny is in judicial sense at a lower lavel than Review.this was held by Apex courtwhile settling the matter.am i correct?
