Eugеne M. Harris has asked this court to review a decision of a Hearing and Appeals Examiner of the Department of Employment Services (DOES or the agency) holding that an injury which Harris allegedly suffered after the effective date of the Worker’s Compensation Act of 1979, D.C.Code §§ 36-301, et seq. (1993) (the WCA or 1979 Act), was not a new injury but merely a “recurrence” of a pre-Act injury, and therefore non-compensa- *406 ble under the WCA. 1 We conclude, on the basis of the examiner’s evidentiary findings, that Harris suffered a post-Act aggravation of a pre-existing injury, and that such aggravation is compensable under the 1979 Act. Accordingly, we rеverse the decision under review and remand the case to the agency for further proceedings.
I.
THE AGENCY PROCEEDINGS 2
This case is of somewhat ancient vintage. 3 Harris has been employed by intervenor Bell Atlantic and its predecessor, C & P Telephone Co., since 1969. In March 1977, while Harris was on company business, the automobile in which he was riding was “rear-ended” by another vehicle, and Harris suffered an acute sprain of the lumbar spine. He was “physically restricted from the performance of his usual employment duties” for approximately six months.
Upon his return to work in the fall of 1977, Harris was placed in a “medically restricted capacity, i.e., light duty.” Hе was not allowed to drive a company car, climb poles or ladders, pull cable, or engage in lifting. Although Harris ceased active medical treatment in or about 1979, his lumbar condition became chronic. With some relatively minor changes, the restrictions on Harris’ activities remained in effect for more than five years following his return to work.
In 1983, Harris was employed in a supervisory capacity as an engineer. The examiner described this position as “sedentary in nature.” In August of that year, C & P’s employees went on strike, and Harris was reassigned “to perform the non-sedentary function of a frame attendant.” The examiner found that Harris was required, among other things,
to lift and carry test sets weighing from ten (10) to forty pounds (40 lbs.); move and climb ladders; pull jumper wire and cables from reels; and, use of a soldering iron. I find that claimant performed said functions for the month of August 1983, and that claimant began to suffer from increasing lumbar complaints.
After the strike ended in September 1983, Harris returned to his “sedentary supervisory position.” The examiner found, however, that “claimant’s lumbar symptoms, which had begun in August, began to increase in intensity.” Further, according to the examiner,
claimant has credibly testified that from September 1983 through March 1985 he attempted self-medication for back pain, and that thereafter, he sought medical intervention for pain in his lumbo-sacral area. Employer has introduced no evidence to contradict claimant’s credible testimony that he began to experience consistent symptoms of pain in his low back in or about August/September 1983, nor any evidence that claimant does not presently suffer from chronic lumbral strain, and therefore, it was found that claimant sustained an injury in or about said period.
(Emphasis added).
Harris did not seek medical assistance for the 1983 injury until March 1985. In 1986, he filed a notice of accidental injury with the Office of Workers’ Compensation.
Harris II,
On May 20, 1994, the examiner issued a Final Compensation Order. Notwithstanding his evidentiary findings, summarized *407 above, and in spite of his recognition that “the aggravation of a pre-existing condition is an ‘injury’ under the Act,” the examiner concluded that Harris was not entitled to any recovery. According to the examiner, Harris had suffered from chronic lumbar strain since 1977, and
[claimant's physicians have not opined an intervening causative factor in claimant’s present infirmity, in the form of claimant’s August 1983 employment-related activities, merely that his 1977 injury has been, once again, rendered symptomatic. Therefore, it has been found that claimant’s injury of in or about August 1983 was a recurrence of his March 1977 acute lumbar strain.
The examiner concluded on the basis of this reasoning that Harris’ claim “is not amenable to adjudication pursuant to the instant Act.” 4
Harris filed an internal appeal to the Director of DOES. The Director took no action on that appeal within the time prescribed by statute, D.C.Code § 86 — 322(b)(2) (1993), and the examiner’s decision became the decision of the agency. Id. Harris filed a timely petition for review by this court.

LEGAL DISCUSSION
A. The Scope of Review.
The scope of our review of the agency’s orders is defined by the now familiar “substantial evidence” standard. Under the District’s Administrative Procedure Act, D.C.Code § l-1509(e) (1987), we inquire
(1) whether the agency has made a finding of fact on each material contested issue of fact; (2) whether substantial evidence of record supports each finding; and (3) whether conclusions legally sufficient to support the decision flow rationally from the findings.
Cruz v. District of Columbia Dep’t of Employment Servs.,
Our review of the agency’s legal rulings is
de novo,
for “[i]t is emphatically the province and duty
of
the judicial department to say what the law is,”
Marbury v. Madison,
The principle that the executive сonstruction of a statute is to be accorded weight applies “especially if such construction has been made by the highest officers in the executive department of the government.”
See
82 C. J.S.
Statutes,
§ 359, at 761-64 (1953 & Supp.1994). In the present case, the interpretation of the WCA which we have been asked to review is that of the examiner; the Director upheld it by failing to act. We conclude that this circumstance reduces in some measure the deference which we should accord to the agency’s construction.
Cf. Commonwealth v. Berlo Vending Co.,
B. Compensability.
Under the WCA of 1979, “[e]very employer subject to this chapter shall be liable for сompensation for injury or death without regard to fault as a cause of injury or death.” D.C.Code § 36-303(b) (1993). Prior to July 26, 1982, which was the effective date of the Act, employers in the District were subject to the provisions of the federal LHWCA, 33 U.S.C. §§ 901,
et seq.,
which is administered by the Secretary of Labor. Injuries incurred before July 26, 1982 continue to be governed by the LHWCA.
Railco Multi-Constr. Co. v. Gardner,
The 1979 Act is modeled in substantial part on the LHWCA which it replaced.
Railco, supra,
Like other worker’s compensation statutes, the Act is to be “liberally construed for the benefit of the employee.”
Railco, supra,
As the court explained in Vozzolo,
[b]enefits under the Act are not limited to employees who happen to enjoy good health; rather, employers accept with their employees the frailties that predispose them to bodily hurt. [T]he fact that an employee is diseased does not bar his right to recover for accidental injury notwithstanding, except for such diseased condition, the injury would not have occurred, and harm resulting from aggravation by the employment of a pre-existing infirmity, it has many times been decided, is injury within the meaning of the Act.

In light of the examiner’s evidentiary findings, the foregoing principles dictate the result of this case. The examiner specifically found that in August 1983, after Harris was removed from his sedentary job and required to work instead as a “frame attendant,” his lumbar symptoms increased in intensity. Rejecting C & P’s contention to the contrary, the examiner further found that Harris “sustained an injury in or about that period.” Although the examiner did not explicitly state that this injury was an aggravation of a pre-existing condition, it is difficult to understand how it could reasonably be described as anything else.
According to the examiner, Harris suffered a “recurrence,” which was not com-pensable. This is not a case, however, in which the “recurrence” was “the result of the natural progression of the [condition], unaffected by any intervening work-connected cause.”
See, e.g., American Casualty Co. of Reading, Pa. v. Britton,
*409
The present case is similar to
In re Compensation of Elliott,
In 1979, following a period of relative stability, Elliott tripped and fell. He suffered immediate pain and was thereafter hospitalized on three occasions. The Worker’s Compensation Board ruled that Elliott had suffered a compensable injury for which Clayton, the second employer, was liable. The Court of Appeals affirmed, holding that although the 1979 incident “injured the same area of claimant’s back, and ... the nature of the pain was the same, it was increased in severity and duration by the trauma ...[,] resulted in an increase in disability, [and thus] warrants a conclusiоn that a new injury occurred.”

This is essentially what happened in the present case.
See also Fisher v. K Mart Corp.,
The examiner cited
Gustafson, supra,
and
Crum v. General Adjustment Bureau,
The employer contends that the examiner’s finding that Harris’ 1983 injury was a “recurrence” is supported by the medical evidence,
9
*410
and that this court should sustain it under the “substantial evidence” rule. This argument, however, avoids the critical question whether thаt “recurrence” was caused by Harris’ work-related activity. The examiner found that it was, and his holding that the injury was not compensable is more in the nature of a legal conclusion than it is a finding of fact. Even if we were to treat the examiner’s characterization of the injury as a “recurrence” as a finding of ultimate fact, we would be required to reject it as inconsistent with his own findings of evidentiary fact and with the controlling law.
See, e.g., In re L.L.,
Accordingly, we conclude that the examiner’s findings compel the conclusion that Harris suffered а compensable injury in 1983. This conclusion is further bolstered by the statutory presumption of compensability and by the principles of liberal construction which apply to the humanitarian legislation we are called upon to construe. Accordingly, the examiner’s decision is vacated, and the case is remanded to the Director of DOES for further proceedings consistent with this opinion.
So ordered.
Notes
. That decision became final for purposes of judicial review when the Director of the Agency failed to rule on Harris’ internal appeal within forty-five days. See D.C.Code § 36 — 322(b)(2) (1993).
. The examiner made extensive evidеntiary findings. Our factual recitation is based on these findings and, in some minor respects, on uncon-troverted documentary evidence.
.For earlier stages of the litigation,
see Harris v. District of Columbia Dep 't of Employment Servs.,
. The examiner cited several decisions holding that injuries incurred prior to the effective date of the WCA cоntinue to be governed by the Longshore and Harbor Workers’ Compensation Act, 33 U.S.C. § 901
et seq.
(the LHWCA).
See, e.g., Gustafson
v.
Int’l Progress Enters.,
. In any proceeding for the enforcement of a claim for compensation under this chapter it shall be presumed, in the absence of evidence to the contrary
(1) That the claim comes within the prоvisions of this chapter....
D.C.Code § 36-321 (1993).
. As this treatise points out, the distinctions among new injuries, aggravations, and recurrences have been typically explored in cases where a worker has suffered two or more episodes of disability with an intervening change of employers or change of insurancе carriers by the same employer. Id. § 95.11.
. The court went on to state that
if the second incident contributes independently to the injury, the second insurer is solely liable, even if the injuty would have been much less severe in the absence of the prior condition, and even if the prior injury contributed the major part to the final condition....

. The medical testimony on which Bell Atlantic relies, when carefully analyzed, lends little support to its thesis. Attached to Bell Atlantic's brief are excerpts from the reports of several physicians who examined Harris. One of them, Louis B. Levitt, M.D. described the change in Harris’ responsibilities in 1983 and noted that ‘‘[wjith this change in job responsibilities the patient had an increase in his symptoms of neck and back pain.” Dr. Anita Herbert, who examined Harris in August 1983, reported that "although [Harris] did not report any trauma, hе reported that he experienced recent exacer-bations of those low back pains. On examination, there was a mild decrease in range of motion of his back.” These reports are consistent with the examiner's basic evidentiary finding — the transfer of Harris from light duty to heavy duty resulted in the aggravation of his prior condition.
The physicians’ reports, and Harris’ failure to seek medical assistance until 1985 for his 1983 injuries, might well support a finding that the aggravation of his prior condition was not extreme and that the 1983 injury was not severe. These considerations, while obviously relevant to the amount of compensation to which Harris is entitled, do not affect our conclusion that whatever injury he did suffer is compensable under the WCA.
