I think a lot of news outlets were mis-stating this yesterday, unfortunately. I read several headlines wording saying the court ruled that new applications were to be accepted.
I just went back to the Politico article and it confirms, as well that it does not apply to new applications:
”the ruling will allow former DACA recipients who failed to renew by an October 5 deadline a chance to submit renewal applications and will also require the administration to allow renewal of applications expiring in the future. The decision does not require officials to accept new applications for DACA status.”
