The way Spencer has been used is that it is the test that any disclosure from a private entity to law enforcement is subject to. Therefore, every organization right now, when they get a request from law enforcement, will look at these Spencer criteria to decide whether or not they will disclose. Again, it's permissive. It does not compel disclosure like a warrant would, for example. This is really the organization making the determination based on the three criteria in Spencer. It would apply to all information. Again, the criteria are “exigent”, “reasonable law” and “reasonable expectation of privacy”.
Therefore, if you're talking about very sensitive health data or genetic information, I think it would be hard to argue that. Unless it's exigent—something's going to explode—or there is a reasonable law that authorizes it specifically, it would be really hard to meet the third criterion, which is that it doesn't attract a reasonable expectation of privacy. It is quite a high bar to meet for lots of those types of information.
