EFF: Courts May Require Search Warrants for Cell Phone Location Records

Except for matters of national security
Or when the NSA do it
Or if it's about terrorism
Or if the police asks the phone companies nicely, and then pardon them for breaking the law afterwards.
The commenter to which I responded got off topic on an anti-government tangent that made a number of assumptions not at all related to the article for no other reason than to make an anti-government rant, which I grant is a cheap source of karma here.
Instead you need at least the supreme court to decide you don't like these people. If you are allowed to tell phone companies to break the law and you will pardon them later - where do you stop?
For example these records have been used in divorce cases to provide evidence of affairs. (If two cell phones have a repeated tendency to meet each other in motel rooms, this is evidence that the carriers of said cell phones did likewise.) Does this ruling on what the police can do affect that at all?
If the divorce is contested (which can happen in a no-fault state), the lawyers for either side can send subpoenas to anyone they like looking for relevant records, and a standard one to send is to the cellphone company. Which can reveal a lot.
My question is whether a sufficient right to the privacy of those records has been established to block those requests in principle.
