The Wyoming Supreme Court this week ruled that dogs trained to detect drugs can sniff a vehicle’s exterior without probable cause.

The opinion by Chief Justice Kate M. Fox, released Wednesday, upholds a district court’s decision to deny the separate motions to suppress evidence by two defendants charged with multiple drug-related counts. Maria Anne Joseph and Jackson Elliot Tarzia argued that the canine sniffs of their vehicles’ exteriors took place without probable cause, and therefore, violated the Wyoming Constitution.

Nearly half—45%—of judges in Wyoming served as prosecutors before they took the bench, according to a Wyoming Truth survey and analysis of all 57 circuit, district and state supreme court judges in the state.
