11 We decide whether an April 4, 2000 order of a Workers Compensation Court (WCC) trial judge correctly denied a request by petitioner, Tony Barnhill (Barnhill or claimant) to require respondent, the Multiple Injury Trust Fund (Fund) 1 to pay him permanent total disability (PTD) benefits that claimant asserts "accrued" between the date of an August 1999 PTD order and the date (mid-February 2000) Fund was directed by the PTD order's terms to begin making weekly PTD payments to him. We hold the trial judge correctly denied the request based on 85 0.8. Supp.1995, § 172 (effective November 4, 1994)-the applicable law on the date of claimant's last job-related injury and the law that unambiguously set the boundaries of Fund's PTD liability to him. Title 85 0.8. Supp.1995, § 172 (E) required a certain formula-based time period elapse before commencement of weekly PTD payments by Fund, where the employer or insurer responsible for paying permanent partial disability (PPD) benefits to a claimant for his/her last job-related injury paid the PPD compensation in a lump sum-the undisputed factual situation involved in this case. 2
2 In that the trial judge was correct, the Court of Civil Appeals (COCA) erred in relying on 1999 legislative amendments to § 172 to justify (a) vacating the April 2000 WCC order and (b) remanding with instruction to the WCC to direct Fund to pay claimant "accrued" PTD benefits. No "accrued" benefits are owed under relevant law, i.e. 85 0.8. Supp.1995, § 172. Today's opinion is consistent with Samman v. Multiple Injury Trust Fund,
PART I. FACTS AND PROCEDURAL HISTORY.
T3 It is uncontested that when claimant suffered his last work-related injury on or about October 31, 1995, he was considered a "physically-impaired person" under the Special Indemnity Fund Act (Act)
3
by virtue of several previously adjudicated job-related injuries. Also undisputed is the fact claimant, his employer and employer's insurеr settled Barnhill's workers' compensation claim for the 1995 injury by a joint petition settlement approved by the WCC in an August 1998 order. The settlement: 1) represented a determination claimant suffered 28% PPD from the 1995 injury and 2) was paid by employer/insurer in a lump sum.
4
After the settlement, as the Act allows, claimant sought PTD benefits from Fund, asserting combination of the last injury with his prior
{ 4 In an August 1999 order the WCC trial judge ruled that combination of the previously adjudicated on-the-job injuries and the 1995 injury did render him permanently totally disabled. 5 The order also provides in pertinent part:
THAT on or about AUGUST 19, 1998, claimant joint petitioned [] his workers' compensation claim ... for injury (or injuries) occurring on OCTOBER 81, 1995, for a total of [$181,000.00; that when divided by claimant's rate of $205.00 equals 189 weeks which must elapse from the date of last payment of temporary total disability (June 16, 1997) before the ... Fund begins weekly payments to claimant (less attorney fee}.
THAT once benefits commence, [the Fund] is ordered to pay compensation to claimant at the rate of $205.00 per week until the claimant (date of birth: April 29, 1964) reaches the age of 65 years, or for a period of five (5) years, whichever is longer (less attornеy fee). 6
The one hundred thirty-nine (189) weeks required to elapse before commencement of weekly PTD benefits ended about mid-February 2000. 7
¶ 5 At the end of February 2000 Barnhill, in essence, sought an order from the WCC to have Fund pay him (apparently in a lump sum) an amount equal to the ordered PTD rate times the number of weeks between the date of the August 1999 PTD order and the date weekly PTD payments were scheduled to begin in February 2000 under the PTD order's terms. 8 The WCC trial judge denied the request in an April 2000 order, obviously concluding no PTD benefits "accrued" during that period under aрplicable law. Claimant appealed.
T6 The COCA vacated the WCC's April 2000 order. It basically held: (1) 1999 legislative amendment of § 172, including addition of the following last sentence to § 172(B), "Multiple Injury Trust Fund awards accrue from the file date of the court order finding the claimant to be permanently and totally disabled[ ]", authorized "accrual" of PTD payments from the time claimant was adjudicated totally disabled (ie. the date of the PTD order) to the date the lapse-time period ended; (2) the 1999 amended version, as opposed to showing legislative intеnt to change 85 0.8. Supp.1995, § 172, was intended to clarify the law and, thus, should be retroactively applied; and (8) apparently, that the "accrued" amount was due claimant immediately after expiration of the lapse-time period. We also note the 1999 amended version of § 172 deleted the lapse-time formula contained in the 1995 version of § 172(E) 9
T7 Three decisions of the COCA [two from Division I and one from Division II] are generally contrary to the COCA decision in the instant case. These cases hold the 1999 amended version of § 172 does not retroaсtively apply when a claimant's last job-relat
PART II STANDARD OF REVIEW.
T8 This case calls for determining the statute-based liability of Fund to claimant where no factual dispute exists. 10 A question of law concerning ascertainment of legislative intent faces us, which necessarily involves statutory interpretation. Statutory interpretation, entailing a legal issue, demands a de movo review standard, 11 ie. a review in which an appellate court has plenary, independent and non-deferential authority to reexamine a trial court's legal rulings. 12
PART III. FUNDS LIABILITY TO PAY PTD BENEFITS WAS STATUTORILY SET BY 85 0.8. SUPP.1995, § 172, THE LAW IN EFFECT AT THE TIME OF CLAIMANTS LAST JOB-RELATED INJURY; BECAUSE THE 1999 AMENDMENT OF § 172 DOES NOT REPRESENT A CLARIFICATION OF EARLIER LAW AND IS NOT ACCORDED RETROSPECTIVE APPLICATION BY EXPRESS LANGUAGE OR BY NECESSARY IMPLICATION, WE FIND NO LEGISLATIVE INTENT TO AFFORD THE 1999 AMENDMENT RETROSPECTIVE SWEEP.
T9 In Special Indemmity Fumd v. Archer,
B. If such combined disabilities constitute [PTD], as now defined by the Workers' Compensation Act, then the employee shall receive full compensation as now provided by law for the disability resulting directly and specifically from such subsequent injury. In addition, the employee shall receive full compensation for his combined disability, as above defined, all of which shall be computed upon the schedule and provisions of the Workers' Compensation Act. The employer shall be liable only for the degree of percent of disability which would have resulted from the latter injury if there had been no preexisting impairment. After pаyments by the employer or his insurance carrier have ceased, the remainder of such compensation shall be paid out of the [] Fund ... in periodic installments. In [PTD] cases the same shall be paid in periodic payments, as set forth in Section 22 of this title, and shall not be commuted to a lump-sum payment. The compensation rate for permanent total awards from the [] Fund shall be the compensation rate for [PPD] paid by the employer in the last combinable compensable injury. Permanent total awards from the [] Fund shall be pаyable for a period of five (5) years or until the employee reaches sixty-five (65) years of age, whichever period is the longer.
E. All weekly payments for [PPD] shall be paid before any claim for benefitsagainst the [] Fund may be paid. In the case of a lump-sum [PPD] award or settlement, such award or settlement shall be divided by seventy percent (70%) of the employee's weekly wage up to a maximum of fifty percent (50%) of the state's average weekly wage, to determine the number of weeks which must elapse before a claim agаinst the [] Fund may be paid.
T10 In Samman v. Multiple Injury Trust Fund, supra, this Court construed 85 O.S8. 1991, § 172 (B) in the face of a claimant's contention he was entitled to "accrued" PTD benefits during the time period between the date of the PTD order against Fund and the date of last payment of PPD benefits by the employer/insurer for the last work-related injury, where the employer/insurer paid the PPD benefits in periodic weekly payments, rather than as here, via a lump-sum joint petition settlement. The 1991 version of § 172 was involved, as it was in effect when the last job-related injury occurred in August 1992. Title 85 0.8.1991, § 172 (B) remainеd unchanged until its amendment in 1999. 13 Sammon stated:
According the ... statutory language [of 85 0.8.1991 § 172 (B)] its plain and ordinary meaning leads to a single, inescapable conclusion, ie., the Fund's liability to make PTD payments can only be satisfied through periodic installments which can begin only after the employer's final PPD payment. Under the law applicable at the time of [claimant's] last compensable injury, a WCC order-that directs accrual of PTD payments while the last employer is making PPD payments and/or then orders a lump-sum payment of these so-called accrued PTD bеnefits from the Fund-is outside the WCC's jurisdiction. (footnote in
{11 Samman also rejected the argument that addition of the last sentence to § 172(B) by 1999 legislative amendment-which is quoted in 16 of PART I above-was intended as a clarification subject to retroactive application. 14 We said:
The primary goal of statutory construction is to ascertain and follow legislative intention. When the Legislature has clearly expressed its intent, the use of additional rules of construction are almost always unnecessary and a statute will be applied as written. In other wоrds, the plain meaning of a statute's language is conclusive except in the rare case when literal construction produces a result demonstrably at odds with legislative intent. The Court also recognizes that by amending a statute the Legislature may haveintended (1) to change existing law or (2) to clarify ambiguous law. The exact intent is ascertained by looking to the circumstances surrounding the amendment. If the earlier version of a statute definitely expresses a clear and unambiguous intent or has been judicially interpreted, a legislative amendment is presumed to change the existing law. Nonetheless, if the earlier statute's meaning is in doubt or uncertain, a presumption arises that the amendment is designed to clarify, i.e., more clearly convey, legislative intent which was left indefinite by the earlier statute's text.
Resolution of the issue presented ... requires the Court to examine the meaning of 85 ©.8.1991 § 172 (B) to determine if the relevant statutory language is susceptible of ambiguous meaning. We have ... concluded that the statutory language in issue is neither unclear nor open to multiple meanings. Undеr the law in effect at the time of [claimant's] last compensable injury, PTD payments were mandated to be by periodic installments, payable after PPD payments by the employer or his insurance carrier had ceased, and were not commutable to Iump-sum payments.
Sans ambiguity-which today we find does not exist-in the 1991 version of § 172(B), the 1999 amendment of the same cannot be said to have been enacted by the Legislature to clarify the earlier law. Further, a reading of the later amendment's language reveals no legislative intent to аfford retrospective force to it. Under the circumstances here present the retroactive application of 85 0.8. Supp.1999 § 172 (B) is simply not sustainable. (footnotes omitted)(emphasis in original)
Samman,
{ 12 Earlier, in Stidham v. Special Indemnity Fund, supra, the last job-related injury having occurred after the effective date of 85 0.8. Supp.1995, § 172, but before the 1999 amendment(s), we were confronted with interpreting the meaning of the lapse-time period provision found in § 172(E) involved in this case. 15 In Stidham, like here, the PPD claim for the last work-related injury was settled via a joint рetition and paid by the responsible employer/insurer in a lump-sum. The PTD order against Fund had directed it to begin paying weekly PTD benefits from the order's date, rather than at the end of the lapse-time period as mandated by § 172(E). When Fund failed to make payments from the order's date, claimant sought the unpaid installments in a Iump sum and he requested their total amount be certified as a judgment for enforcement in the district court. The WCC trial judge denied the request and a three-judge panel of the WCC upheld the denial.
113 We likewise sustained the denial. Stidhom ruled, to the extent the initial PTD order had sanctioned weekly PTD payments during the lapse-time period, it was facially void and outside the jurisdiction of the WCC because in obvious non-compliance with § 172(E)'s statute-imposed liability of Fund. In rejecting the claimant's assertion he was entitled to the weekly PTD benefits-in a lump sum-argued to have "accrued" from the date of the PTD order under that order's terms, we said:
[Section 172(B)] now directs the Fund benefits to begin at a time certain. Their payment may not commence until employer-paid weekly [PPD] benefits had come to an end, or in the case of a lump-sum award (or settlement), until a statutory calculation of time for payment would have passed. The manner currently prescribed by § 172(E) for fashioning the payment schedule for an award against the Fund is the outer limit of the Fund's statutory lability. It must henee also be construed as the jurisdictional boundary of the trial tribunal's power to act. (emphasis in original)
{15 Since the law in effect when Barnhill last suffered a work-related injury so plainly and unequivocally expressed legislative intent, the 1999 amendment of § 172 cannot be deemed to have merely clarified the earlier law. Saemman, supra,
116 The general rule is that statutes have prospective operation unless the purpose and intent of the Legislature to give them a retroaсtive effect is expressly declared or necessarily implied from the language used. Houck v. Hold Oil Corp.,
PART IV. SUMMARY.
117 Claimant seeks to impose upon Fund liability for the payment of PTD benefits he argues "accrued" from the filing date of the order adjudicating him permanently totally disabled. The statute that set Fund's liability to him for PTD benefits was the one in effect on the date of his last job-related injury, 85 O.S8. Supp.1995, 172. When applied to the pertinent undisputed facts involved in this case, that law plainly and unambiguously mandated a statutorily, prescribed/formula-based lapse-time period before Fund was responsible for commence ing periodic PTD benefit payments to him. Claimant's quest here is incompatible with the mandаtory lapse-time formula and he is not entitled to the so-called "acerued" benefits he seeks. The WCC trial judge correctly recognized claimant had no statutory entitlement to the sought-after benefits. Further, because 85 O0.S. Supp.1995, 172-insofar as it delimits Fund's liability to claimant-is clear and unambiguous, the
{ 18 The Court of Civil Appeals' opinion is VACATED and the Workers' Compensation Court's April 4, 2000 order is SUSTAINED.
Notes
. The Multiple Injury Trust Fund (Fund) was formerly known as the Special Indemnity Fund. The name was changed in 1999. 85 O.S. Supp. 1999, § 173.
. Title 85 O.S. Supp.1995, § 172, as the text notes, was the version of § 172 in effect on the date of claimant's last work-related injury and it became effective on November 4, 1994. See 1994 Okla. Sess. Laws (Second Extra. Sess.), Ch. 1, §§ 42 and 56. Subsection (E) was added to § 172 in a Second Extraordinary Session of the Oklahoma Legislature and was the only change made аt that time to § 172. See 1994 Okla. Sess. Laws (Second Extra. Sess.), Ch. 1, § 42.
. 85 0.$.1991, § 171 et seq., as amended.
. The settlement amount was $31,000-$28,495 designated to be for the permanent partial disability (PPD) caused by the 1995 injury and the remaining $2,505 for disfigurement. Although we need not detail the amounts, the joint petition indicates part of the settlement sum went to pay claimant's attorney fees and the order approving the joint petition shows part went to pay a Special Indemnity Fund Tax. The joint petition also reflects claimant received about another $31,000 from employer or its insurer for a period of tеmporary total disability (TTD) following the 1995 injury.
. The August 1999 order details previous job-related injuries in 1991, 1992, 1993 and 1994.
. The one hundred thirty-nine (139) week time period was actually arrived at by dividing $28,495 (that part of the settlement representing PPD) by $205 and the disfigurement amount was not included in the equation.
. Recently, in Multiple Injury Trust Fund v. McGary,
. No issue is raised in this appeal as to whether Fund timely began weekly permanent total disability (PTD) benefits in conformity with the August 1999 order at the end of the one hundred thirty-nine (139) week period. We also note that in his May 17, 2001 brief in opposition to certio-rari, claimant seems to indicate, or allude to, his belief that the lapse-time period will not expire until April 2002. Under our review of thе record, we cannot understand the indication or such a belief. Under the plain wording of the August 1999 order awarding PTD benefits, the lapse-time period began running on June 16, 1997 (the last date TTD was paid) and would end about mid-February 2000.
. For the pertinent terms of 85 O0.S. Supp.1999, § 172 (B) and (E) see note 14, infra.

. The full text of 85 0.S. Supp.1999, § 172 (B) provides:
B. If such combined disabilities constitute [PTD], as defined in section 3 of this title, then the employee shall receive full compensation as now provided by law for the disability resulting directly and specifically from the subsequent injury. In addition, the employee shall receive full compensation for the combined disability, as above defined, all of which shall be computed upon the schedule and provisions of the Workеrs' Compensation Act. The employer shall be liable only for the degree of per cent of disability which would have resulted from the subsequent injury if there had been no preexisting impairment. After all [PPD] payments by the employer or the insurance carrier of the employer have ceased, the remainder of the compensation shall be paid out of the [] Fund provided for in Section 173 of this title, in periodic installments. In [PTD] cases the same shall be paid in periodic payments, as set forth in Section 22 of this title, and shall not be commutеd to a lump-sum payment. The compensation rate for permanent total awards from the [] Fund shall be the compensation rate for [PPD] paid by the employer in the last combinable compensable injury. Permanent total awards from the [] Fund shall be payable for a period of five (5) years or until the employee reaches sixty-five (65) years of age, whichever period is the longer. [] Fund awards shall accrue from the file date of the court order finding the claimant to be permanently and totally disabled.
Subsection (E) of § 172 was also amended by 1999 legislation. Title 85 0.S. Supp.1999, § 172 (E) provides:
"Reopening any prior injury claim other than the last employer injury claim shall not give a claimant the right to additional [] Fund benefits. All weekly payments by the last employer or the insurance carrier of the employer for [PPD] shall be paid before any claim for benefits against the [] Fund may be paid."
As can be seen, the formula-based lapse-time period was deleted from § 172(E).
. Our opinion in Stidkam, note 10, supra, refers to 85 0.S. Supp.1994, § 172 (B), rather than to the 1995 Oklahoma Statutes Supplement. As set out in notе 2, supra, subsection (E) became effective on November 4, 1994; it was added to § 172 in a Second Extraordinary Session of the Oklahoma Legislature; and was the only change made at that time to § 172. It first appears in the 1995 Oklahoma Statutes Supplement, rather than the 1994 Supplement.
. Stidham, note 10, supra, also recognized that 85 O.S. Supp.1995, § 172 (E) abrogated the teaching of Special Indemnity Fund v. Bryant,
. Claimant, in essence, argues in his merit brief of June 20, 2000 that because 85 O.S. Supp. 1995, § 172 (B) contains the following sentence, "[in [PTD] cases the same shall be paid in periodic payments, as set forth in [85 O.S. Supp. 1995, § 221, and shall not be commuted to a lump-sum{,]" and § 22(1) generally provides that PTD shall be paid during the continuance of the total disability, that benefits from the Fund are owed-even if not immediately payable-from the date of the PTD order. The argument is unavailing. Section 172(B)'s referеnce to § 22 is merely meant to point to that section of the Workers' Compensation Act, 85 0.$.1991, § 1 et seq., as amended, to be consulted for the amount of PTD periodic weekly payments to be made by the Fund. It is 85 O.S. Supp.1995, § 172 (B) and (E) which control the duration of the statutory liability of the Fund to claimant, not § 22(1). The time restrictions found therein are controlling. See Multiple Injury Trust Fund v. Hill,
. According to the August 1999 PTD order Barnhill was born in April 1964 and he will be eligible for Fund PTD benefits from approximately February 2000 [expiration of the lapse-time period of 85 0.8. Supp.1995, § 172 (E) ] until he reaches the age of sixty-five (65) years old; ie. for about thirty (30) years, as he was thirty-five (35) years old when Fund benefits were to begin in February 2000. If he was granted PTD benefits from the date of the PTD order his total PTD benefits from Fund would obviously be increased by approximately six months of benefits.
. In today's pronouncement it is unnecessary for us to definitively reach the meaning of the 1999 amendments to § 172. In the case of Multiple Injury Trust Fund v. Pullum,
. Our ruling in this cause is consistent with the generally applicable statutory rule in workers' compensation cases that: '"[blenefits for an injury shall be determined by the law in effect at the time of the injury...." 85 O.S. Supp.1997, 3.6 (F).
