Your criminal record is marked with a "case awaiting trial" designation when you're arrested. This indicates that you've been formally accused of a crime, and the case is pending resolution.
Usually, this designation will appear as "illicit activity identified," which could lead others to believe you have a criminal record. After the case is resolved (either charge are dropped, a conviction is made, or you successfully defend yourself), the police will remove or update the designation accordingly. However, in some cases, the police may fail to update the designation after resolving the case.
If this happens, the "case awaiting trial" designation will remain on your record indefinitely, potentially resulting in a permanent criminal record.
