I think the change is just going to be the courts utterly tied up with regulation challenges. The FDA, FCC, FAA et.al. can still write regulations on Congress' behalf, but they no longer have the final say, and the courts don't have to abide by their expertise. And so I see the courts filling up with these exact lawsuits that will take years to resolve. This was the status quo - well not quite, a separate decision effectively undid the 5 year limitation on challenging old regulations - but I think that companies are going to be a lot more litigious now than they were (and there's a lot more of them). WRT this specific case, we'll have to see whether the courts issue an injunction to prevent the unlocking regulation to stop taking effect.
