The court based their final decision of the Carpenter vs. United States, 585 U.S.
(2018) case that
the court interpreted the part of the Constitution it based its decision on was that it was based on
protection for the individual's privacy rights.
They needed to ensure the correct protocol was
followed and the information was accurate. It reached its decision because the Court had to
ensure that the fourth amendment was not violated in getting cell phone records from the third
party. It also tells us that request was granted so they were able to get the search warrant and the
cell phone records to get the best and accurate information needed for the case. One previous
decision that the Court relied upon in reaching its conclusion was that the defendant not only
gave his location away freely, but he also voluntarily reveals the locations history he was present
at from his device at the time of the crimes showing that he was guilty of the crimes that were
committed.
