That's also an interesting point, because there's a body of case law, as I recall, at least in British Columbia, that talks about waiver of charter rights. My understanding—and it's been a number of years—is that one person cannot waive the charter rights over another person's.... If a person has an expectation of privacy in a device and there is joint control of the device, person A can't waive person B's expectation of privacy.
Are you with me here so far?
