The emergency laws seems like an interesting one because whatever its plausible justification, in practice, it seems like the only downside it would curb would be moreso any governmental liabillity for lawsuits and judicial review.

If the government wants to do something, it will do it and the courts will maybe take it up later. Any measure they say the needed to do they would probably just do anyway regardless of the true necessity or for whom it was evaluated in that light, the only benefit to an emergency law in that context seems to be dissolution of regular liabillity and having a talking point about being justified after the fact.

Seems like it incentivizes an opening for bad behavior
