Predominant/Dominant Aggressor Law

When the officer has probable cause to believe that family or household members or intimate partners have assaulted each other, the officer is not required to arrest both persons. The officer shall arrest the person whom the officer believes to be the primary aggressor. In making this determination, the officer shall make every reasonable effort to consider: (A) The intent to protect victims of domestic violence under RCW  10.99.010; (B) the comparative extent of injuries inflicted or serious threats creating fear of physical injury; and (C) the history of domestic violence of each person involved, including whether the conduct was part of an ongoing pattern of abuse.
