On April 2, 1948, petitioner was injured in the course of her employment, and on March 14, 1952, the Industrial Accident Commission awarded her a permanent disability rating of 100 per cent. On April 1, 1953, the next to the last day of the five-year period after the injury, her employer’s insurance carrier filed a petition with the commission to have the award amended to reduce the percentage of permanent disability. After proceedings were had the commission set aside its award and ordered that petitioner's permanent disability be reduced to 41% per cent.
Petitioner seeks to have the last mentioned order annulled on the grounds that: (1) The commission was without jurisdiction to make the order after the five-year period under the workmen’s compensation laws (Lab. Code, § 5804); (2) the 1949 amendment (Stats. 1949, ch. 677, § 2) to section 5804 which increased the period of time from 245 weeks to five years should not be retroactively applied to the instant proceedings; (3) the findings of the commission do not support the order sought to be annulled. In view of the result reached herein that the commission should not have made the order after the expiration of the five-year period and that the order must be annulled on the first of the grounds heretofore set forth, it is unnecessary to discuss the other contentions.
Section 5803 of the Labor Code provides generally that the commission has continuing jurisdiction over its awards and at any time upon notice and opportunity to be heard it may rescind, alter or amend such award, good cause appearing therefor. This power includes the right to diminish, increase or terminate, within the limits mentioned in the workmen’s compensation laws, any compensation awarded on the ground that the disability of the person in whose favor the award was made has recurred, increased, diminished or terminated. That section is qualified, however, by section 5804 which reads: “No award of compensation shall be rescinded, altered, or amended after five years
*794
from the date of the injury. Provided, however, that after an award has been made finding that there was employment and the time to petition for a rehearing or reconsideration or review has expired or such petition if made has been determined, the commission upon a petition to reopen shall not have the power to find that there was no employment.” (See
Subsequent Injuries Fund
v.
Industrial Acc. Com.,
The commission claims that inasmuch as the carrier’s application to amend the award was filed with it within the five-year period, the commission could make the amendment after the five years had expired. It has been held in considering
section 64.10, supra,
that an application by an employee for new and further disability, if filed within the five-year period, is timely and the commission may determine the question after the expiration of the period.
(Gobel
v.
Industrial Acc. Com.,
This holding is in accord with the express wording of section 5410, supra. That section provides that an “injured employee” may “institute,” that is, commence proceedings for compensation within five years after the date of the injury on the ground that the original injury has caused new and further disability. There is no restriction on the time within which the commission may act, hence it may act on the proceedings commenced within the five years after the five years have elapsed. Section 5410 is in that *795 portion of the workmen’s compensation laws dealing with “Limitations of Proceedings.” (Lab. Code, div. 4, pt. 4, ch. 2.)
On the other hand, sections 5803 and 5804, supra, which are applicable in the instant case, are in the part of the code dealing with “Findings and Awards” * and there is nothing in section 5804 about the time within which proceedings to amend or rescind an award may be commenced. The restriction is a flat declaration that no award “shall” be rescinded or amended after five years from the date of injury. The different language in the two sections (5410 and 5804) indicates that a different rule was intended. When the Legislature intended that a proceeding was timely when commenced within the period, even though decided later, it so stated (Lab. Code, § 5410, supra). Its failure to so provide in section 5804 indicates that it did not intend the same result. † It is true that the foregoing interpretation of section 5804 means that five years’ time is not given in which to apply for relief under section 5803, because obviously an application on a date such as the next to last day could not be decided until after the time limited, but section 5804 does not purport to allow five years in which application may be made for relief (as does §5410). On the contrary, it provides that the commission may not amend or rescind its award after that time.
The distinction between the two sections was recognized in
Westvaco etc. Corp.
v.
Industrial Acc. Com., supra,
“It is well settled that the commission has power to continue its jurisdiction to determine new and further disability beyond the five-year period, where application is made within that period....
“If the true and exclusive meaning of section 5410 is that there can be no new and further disability application where there was a permanent disability award, then the employee here must be denied any increase in permanent disability over the percentage found in the first order, because the commission failed to amend that order within the five-year period and his present condition does not constitute ‘new and further disability’ within the meaning of that section. . . . During the five-year period the commission could under section 5803 amend or alter its previous order, or could act under section 5410.
After the five-year period, only section 5410 com be used, and then, only if a prior proceeding is filed under it.”

Broadway-Locust Co.
v.
Industrial Acc. Com.,
In the instant ease the proceeding could not have been taken under section 5410 because the employer’s carrier filed the application. It was necessarily under sections 5803 and 5804. Section 5410 refers only to a proceeding by the “injured employee.” By no device may that phrase be held to include an employer or his carrier.
*797
The employer’s insurance carrier claims that the foregoing interpretation of the sections discussed is contrary to that heretofore given to them by the commission. That is at least doubtful, but in any event, a former administrative construction contrary to the statutes cannot control.
(Groves
v.
City of Los Angeles,
The carrier urges that the foregoing construction is a denial of due process and equal protection of the law
*
because a different period of time is given to employees (§ 5410, infra) than to employers or their carriers (§ 5804, supra) in which an award may be altered. There are manifest differences between an injured employee and his employer and the latter’s insurance carrier upon which the Legislature could base a reasonable classification. The whole theory of workmen’s compensation laws recognizes such a distinction. The distinction has been made in statutes regulating attorney’s fees which have been upheld. (See
Marczeski
v.
Pittsburgh Steel Ore Co.,
The award is annulled.
Gibson, C. J., Shenk, J., Schauer, J., Spence, J., and McComb, J., concurred.
The petition of respondent Guarantee Insurance Company for a rehearing was denied July 24, 1956.
Notes
It (§ 5804) has been said to be a jurisdictional limitation.
(Douglas Aircraft Co.
v.
Industrial Acc. Com., supra,
Compare section 473 of the Code of Civil Procedure which provides that an application for relief from default must be made in six months and section 660 which provides that the court has no power to pass on a motion for a new trial after 60 days after notice of entry of judgment, etc.
