Or to put it another way, he has less than a year left, so Federal judges now feel safe that they can rule against him without being pummeled to death with charges of RAAAAAACISM.
So many of these actions have to meet the hurdle of ‘standing’ in order to be heard in the federal courts. And for most of these cases, individual citizens do not have the ‘standing’ to challenge illegal actions by our government. Part of the reason for this is to prevent the system from being overrun by nuisance suits, but this also severely limits the ability of citizens in to hold their government accountable.
In some cases, like the immigration situation, state governments have standing and are fighting the good fight. In others, only Congress has standing to sue against encroachment on their powers. With a few exceptions, our Congressional leaders have been very slow and reluctant to defend Congressional powers against encroachment by this Executive branch.
