Opinion
The Subsequent Injuries Fund seeks review and annulment of an award of the Workmen’s Compensation Appeals Board which found real party in interest (Wilbur D. Royster, hereinafter “applicant”) to be 100 percent permanently disabled, attributing 69V2 percent to an industrial injury during the period September 1, 1967 through March 30, 1971 and 301A percent to a preexisting injury to the back and heart which had previously been awarded to applicant.
The Facts
On January 21, 1971, the board found that applicant had sustained an industrially caused, cumulative injury to his heart and back during March 1, 1947 through February 28, 1967, and awarded him a partial permanent disability rating of 301Ó percent (case No.
The Fund contends that “the referee used an improper method of determining the industrial injury” and that “even if the formula used by the referee were proper, the evidence would not support the finding of 69% % industrial disability” for the second injury.
The mathematical formula governing benefit payments to applicant clarifies the reason the Fund is seeking review. If the initial award to applicant (
We note initially that the Fund does not contend that applicant is not entitled to a life pension; nor is there a question raised as to the amount *408 of each benefit payment under the life pension. The only real issue on review is when the Fund’s obligation to make the life pension benefit payments begins.
The issues as stated in the Fund’s petition and brief seem to imply that the Fund is seéking a shifting of liability from itself to the employer (who is not a party to these proceedings). Such a shifting of liability may not be accomplished.
Where an employee has permanent disability from an industrial injury which, in conjunction with a preexisting disability (either industrial or nonindustrial), produces a combined disability of 70 percent or more of total disability, he may also apply for payment of the difference 3 between the rating for his industrial injury and the total disability percentage. 4 These benefits are made payable by law out of a special legislative appropriation administered by the Fund.
According to the rules of the Workmen’s Compensation Appeals Board, whenever it appears likely that benefits may be payable from the Fund in addition to normal permanent disability benefits, a written application for such benefits should be filed. This allows the Fund to be joined in the proceedings. Where the Fund is not joined, it is entitled to litigate the question of its own liability for life pension benefit payments.
(Brown
v.
Workmen’s Comp. Appeals Bd.,
For purposes of reaching the merits of the Fund’s contentions, we construe its petition as solely requesting relief within the allowable confines hereinabove set forth.
The Fund’s first assignment of error is that the board used an improper method in determining the percentage of total disability which was attributable to the second injury. In determining the extent of applicant’s disability, the board concluded that due to the cumulative heart injury, applicant was 100 percent disabled. In order to ascertain what percentage of applicant’s total disability was attributable to the second injury (71 VN 31861), the board deducted the previous partial permanent disability award of 30*A percent, arriving at its award of 691A percent. The Fund contends that this method of determining the percentage rating violated the law as set forth in

The rule governing the employer’s liability in a case of successive injuries such as those involved in the instant case is set forth in

Thus, under the facts of this case, the formula used by the board to apportion the amount of disability attributable to the second injury was not erroneous. The

case which dealt with a preexisting disease which was “lighted up” by a single trauma (Lab. Code, § 4663) is not controlling.

was specifically distinguished in
Hutchinson,
where it was noted that the proper method of apportionment to be used in cases of successive injuries of the same nature is to determine the aggregate amount of the disability attributable to the injuries and then subtract the previously rated and compensated disability to determine the liability for the second injury. That is what the board did in the instant case.

Industrial Acc. Com.,
The Fund’s second contention is that the board’s finding of 69Vi percent disability is not supported by the evidence.
It is an elementary rule of appellate procedure that a decision of the board will be reviewed on the basis of whether the record contains substantial evidence to support the decision.
(LeVesque
v.
Workmen’s Comp. App. Bd.,
“The natural aging process and the degenerative arthritic process accounts for seventy-five percent of the patient’s present permanent partial disability factors.”
The recommended permanent disability rating incorporated the recommendation of Goldman that applicant is “precluded from heavy lifting or exposure to tension or strain.” Under the facts it is clear that the recommended rating was intended to encompass applicant’s heart injury. The injury to applicant’s back was subsumed within the rating. (See

Petitioner’s application for a hearing by the Supreme Court was denied August 28, 1974.
Notes
Labor Code section 4658 provides: “If the injury causes permanent disability, the percentage of disability to total disability shall be determined, and the disability payment computed and allowed, according to subdivision (a). However, in no event shall the disability payment allowed be less than the disability payment computed according to subdivision (b).
“(a)
Column 1—Range of percentage of permanent disability incurred
Column 2 — Number of weeks for which two-thirds of average weekly earnings allowed for each 1 percent of permanent disability within percentage range:
Under 10 3
10-19.75 4
20-29.75 5
30-49.75 6
50-69.75 7
70-99.75 8
“The number of weeks for which payments shall be allowed set forth in column 2 above based upon the percentage of permanent disability set forth in column 1 above *407 shall be cumulative, and the number of benefit weeks shall increase with the severity of the disability. The following schedule is illustrative of the computation of the number of benefit weeks:
Column 1—Percentage of permanent disability incurred:
Column 2—Cumulative number of benefit weeks:
5 15.00
10 30.25
15 50.25
20 70.50
25 95.50
30 120.75
35 150.75
40 180.75
45 210.75
50 241.00
55 276.00
60 311.00
65 346.00
70 381.25
75 421.25
80 461.25
85 501.25
90 541.25
95 581.25
100 for life
“(b) Two-thirds of the average weekly earnings for four weeks for each 1 percent of disability, where, for the purposes of this subdivision, the average weekly earnings shall be taken at not more than seventy-eight dollars and seventy-five cents ($78.75).’’
The difference to applicant between either form of benefit payment is minimal. Suppose that 1514 percent was attributable to the back injury (as applicant contends—no specific figures are urged by the Fund). This would increase the 6914 percent by 1514 percent, or 61 additional permanent disability weekly payments (1 percent entails 4 weekly payments) at $52.50. The weekly life pension payment of $48.46 would then not begin until the expiration of the additional 61-week period. The difference to applicant is the sum of $246.44. The difference to the Fund is much greater (at least $2,956.06, plus some credit against the county for its responsibility for the life pension).
The employer is only liable to the extent that the second injury is industrially caused.
