An interesting US Supreme court case about privacy and cellular phones.

On Wednesday, the supreme court will consider whether the government must obtain a warrant before accessing the rich trove of data that cellphone providers collect about cellphone users’ movements. Among scholars and campaigners, there is broad agreement that the case could yield the most consequential privacy ruling in a generation.

Less appreciated is the significance of the case for rights protected by the first amendment. The parties’ briefs make little mention of the first amendment, instead framing the dispute – for understandable reasons – as one about the right to privacy. Yet the court’s resolution of the case is likely to have far-reaching implications for the freedoms of speech, press and association.
