Criminal Cases in the Blaine County District Court
In Idaho the public criminal record is the court file. Criminal cases from Blaine County are heard by the Blaine County District Court, which hears felonies, civil cases over $10,000 and appeals from the magistrate division; the Magistrate Division takes misdemeanors, traffic cases, small claims, probate and divorces, and the file of each case is kept by the Clerk of the District Court.

The Idaho Criminal History and Your Own Copy
Idaho is one of the states that lets anyone look up another person's statewide criminal history: name-based conviction checks are open to the public, through the Idaho State Police Bureau of Criminal Identification. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
To see your own record, the route is a fingerprint-based request to the Bureau of Criminal Identification. The state page SearchSystems verified for it is at isp.idaho.gov/bci/criminal-history.
