This Note explores the CSLI debate by analyzing the circuit courts’ decisions, scholars’ disagreement with those decisions, and the alternative approaches offered to protect and evaluate CSLI records.

In support, it argues that this theory best addresses the concerns with CSLI tracking and proposes a standard that courts may use to apply it.
