I have spoken to the lawyer and had a back and forth with him. So - with all due respect to Curtis, who I think has done his homework and knows the strengths and weaknesses of his case, I will give my current assessment here. I did discuss the lawsuit in a video with my earlier assessment and Curtis did reach out to me and confirm that my assessment at that time was fair and accurate.
The "non-discretionary duty to adjudicate" is frankly BS. Lawyers sometimes need to state some things in a strong way to provide a platform from which to make an argument, in this case the intent being to create the conditions to reinforce the threat of an argument. Meaning - he is trying to make the case sound strong so that the defendants will be more likely to "perform" to avoid the lawsuit being argued in court.
The cases where visas have been issued after the end of the year is murky at best. Some visas have been accelerated before September 30, and therefore "set aside" for issuance later, but even when a court orders someone to do something, that party may be bound by other laws and not able to do what the court says. So - a court could order the government to issue the visa (at which point the lawyers could claim a win) BUT the visa still might not be issued - because issuing would be a contradiction of an existing law. That is pretty much the stalemate that exists at the moment.
So, the lawsuit is intended to speed up processing for people on the lawsuit. That won't help at all if the ban is extended, or the embassies remain closed, or the numbers are retrogressed, or if KCC have not finished processing of documents. So - if I were in this position to gamble $1000 , I might do it, but I would wait until I saw embassies were opening, the ban isn't extended and the VB is released. That means waiting until mid/late June. And at that point I would also be checking/confirming that my documents are processed. But frankly, if those conditions exist, I might not need the lawsuit anyway....
