Totality of the circumstances

In the law, the totality of the circumstances test refers to a method of analysis where decisions are based on all available information rather than bright-line rules.^[1] Under the totality of the circumstances test, courts focus "on all the circumstances of a particular case, rather than any one factor".^[2] In the United States, totality tests are used as a method of analysis in several different areas of the law.^[3] For example, in United States criminal law, a determination about reasonable suspicion or probable cause is based on a consideration of the totality of the circumstances.^[4]
