A closely watched privacy case was dealt a major blow today, as the Supreme Court declined to hear an appeal over police obtaining cellphone location records without a warrant.

The case centers around Quartavious Davis, who was found guilty of a series of Florida robberies that happened in 2010. Police were able to tie Davis to the robberies using location information obtained by Davis' cellphone carrier, MetroPCS. Davis challenged the decision, arguing that, as police failed to get a warrant for the information, the government was in violation of the Fourth Amendment.

Meanwhile, although a patchwork of similar cases have been unfolding across the country, the Supreme Court has yet to take up the issue.
