How does a de novo review apply to an order sustaining a demurrer?

We apply de novo review to an order sustaining a demurrer. A trial courts decision to deny leave to amend will be left undisturbed unless we conclude that there was an abuse of discretion. ( Aubry v. Tri-City Hospital Dist. (1992) 2 Cal.4th 962, 966967, 9 Cal.Rptr.2d 92, 831 P.2d 317 ;
