In MacDonald v. Gourley (2002) 102 Cal.App.4th 568, the arresting officer was the only officer involved in the traffic stop. The arresting officer submitted both a sworn and an unsworn report, and the hearing officer admitted both into evidence. (Id. at p. 574.) The trial court granted a petition for an alternative writ of mandate, relying on Solovij for its finding that the sworn report did not contain all relevant information to support the detention and that the unsworn report was inadmissible. (Id. at pp. 574-575.) Division Three reversed.
