an express statutory duty; it is not a money action against the state and is outside the purview of the claims statute. (County of Los Angeles v. Riley, 20 Cal.2d 652, 662 [128 P. 537].)
We agree with the Attorney General’s advice to the Controller. The statutory plans for surviving spouses and surviving children parallel, diverging only as to duration of the benefit period. As adopted in 1970, the surviving children law did not expressly deny payment of the lump sum benefit. Nevertheless, the exclusion was implicit. Of key significance is section 75096, the first paragraph of which we quoted earlier. It declares that the surviving children’s monthly allowance shall be that “payable pursuant to Section 75091.” The latter is the statute fixing the mathematical formula for surviving spouse benefits. As we have seen, it expressly designates the monthly survivor allowance as an alternative, not an addition, to the lump sum payment. By incorporating the terms of section 75091 in the surviving children statutes, section 75096 manifests a parallel design to exclude the lump sum benefit when the surviving children allowance is payable.
A statute adopted after Judge Fraga’s death reinforces this interpretation of the law prevailing at his death. In 1973 the Legislature added section 75098 to the surviving children law. It provides in part: “If an allowance is paid under this article no payment shall be made pursuant to Section 75104 or Section 75104.5 ....” Although the substantial amendment of a statute ordinarily infers an intent to change the law, statutory events often warrant the inference that the Legislature intended to clarify preexisting law. (W. R. Grace & Co. v. Cal. Emp. Com., 24 Cal.2d 720, 729 [151 P.2d 215].) In view of its consistency with the result implicit in the earlier law, the 1973 amendment is only a clarification, not a change.
Appellant invokes the rule that ambiguous pension laws will be liberally construed in the applicant’s favor. (Wendland v. City of Alameda, 46 Cal.2d 786, 791 [298 P.2d 863]; LePage v. City of Oakland, 13 Cal.App.3d 689, 695 [91 Cal.Rptr. 806].) That rule applies when the meaning of the pension lav/ is doubtful. (Wendland v. City of Alameda, supra.) The cardinal principle, of course, is fulfillment of the legislative objective. When that objective is as distinct as it is here, the rule for resolving judicial doubt will be reserved for some other case. The law in
