New York’s law, which Democratic Gov. Kathy Hochul signed late last year, is poised to take effect later this year. X maintains that the measure impinges on free speech rights and on a 1996 federal law that, among other things, lets internet platforms moderate posts as they see fit.

X said the law known as the Stop Hiding Hate Act violated the First Amendment and state constitution by subjecting it to lawsuits and heavy fines.
