It says right in the article it was with the help of an immigrants rights group. They were illegally pushed onto a plane and flown to Martha's Vineyard without anyone knowing they were coming. Desantis and his henchmen broke the law, and this judge agrees and has allowed them to bring a lawsuit against them.
Also, people on US soil are to be afforded the rights of the constitution.
Even if someone (like the ACLU) does take this up, these people are jobless and homeless. Can they keep up a suit if they're deported? Will pursuing it be high on their list of priorities (over, you know, food)?
There are so many migrant rights organizations who will be happy to get them lawyers and pursue these cases. It has the potential to ensure this never happens again (through the back door of making it far too high a liability for the transportation companies).
Hell, this could even end up affecting the routine bus trips. At minimum, create very clear disclosure and consent requirements for the migrants, which would be a huge win.
Look, I know you're enjoying that self-righteous high right now but I think you've misunderstood my position.
My point was that while it's great that a judge has given these people standing, they're not really in an economic position where they're able to file lawsuits (and I'm not sure if they even can file lawsuits in US courts when they're non-citizens).
Fortunately, based on the other comments it sounds like they are getting help, and someone else is filing lawsuits on their behalf.
I don't know why people are downvoting you so much. It's a valid question/concern.
But yeah, the important part of the ruling is that they can sue. If they ruled against, it would have meant no other migrants would have had standing either (or, that's my understanding).
