What is the test for reviewing a judgment dismissing a complaint after a demurrer has been granted?

"In the construction of a pleading, for the purpose of determining its effect, its allegations must be liberally construed, with a view to substantial justice between the parties." (Code Civ. Proc., 452.) When "reviewing a judgment dismissing a complaint after the granting of a demurrer without leave to amend, courts must assume the truth of the complaint's properly pleaded or implied factual allegations. . . . In addition, we give the complaint a reasonable interpretation, and read it in context. [Citation.]" (Schifando v. City of Los Angeles (2003) 31 Cal.4th 1074, 1081.)
