Does a plaintiff have to prove that the operative complaint can be amended to state a cause of action?

Singh's arguments do not meet the standard for demonstrating an abuse of discretion by the trial court in denying him yet another opportunity to amend the operative complaint. As explained above, when determining whether the court abused its discretion by sustaining a demurrer without leave to amend, "[t]he burden of proving such reasonable possibility is squarely on the plaintiff." (Blank v. Kirwan, supra, 39 Cal.3d at p. 318.) Singh failed to make any showing of how the operative complaint could be amended to state a cause of action. He merely "requests leave to amend." That is insufficient.
