How does the history and background of a statutory provision affect a court's interpretation of the statute?

"Additionally, "[w]e examine the history and background of the statutory provision in order to ascertain the most reasonable interpretation of the measure." [Citation.] (Doe v. City of Los Angeles (2007) 42 Cal.4th 531, 543 [67 Cal.Rptr.3d 330, 169 P.3d 559].) Even where the plain language of the statute dictates the result, the legislative history may provide additional authority confirming the court's interpretation of the statute. (Id . at p. 544 [67 Cal.Rptr.3d 330, 169 P.3d 559].)" (Boy Scouts of America National Foundation v. Superior Court, supra, 206 Cal.App.4th at p. 443, 141 Cal.Rptr.3d 819.)
