“It does not follow by any means from that lack of jurisdiction that the court should entertain such arguments if, in substance, their purpose is (as here) to make a collateral attack on the decision to make an order.”
“SIAC had no jurisdiction to consider the timing of the deprivation order. SIAC noted, correctly in my judgment, that the statutory scheme envisages two distinct stages. First, the decision to deprive and then (but separately) the deprivation order. SIAC is not empowered to hear an appeal against the deprivation order, still less its timing. As SIAC observed, it is difficult to see how a decision lawfully made could become unlawful in consequence of the timing of the subsequent order.”
“UnlessSIAC has jurisdiction to consider the timing of the making of the deprivation order as part and parcelof the decision to make the order, it cannot have jurisdiction to determine an appeal against the timing and its consequence” because the statutory scheme provides for two distinct steps and because, even if there was jurisdiction to determine a challenge to timing, SIAC considered it difficult to see “how a decision, lawful when made, could be made unlawful by the timing of a subsequent order”
